‘Not available in your region’: what is a VPN and how can I use one safely?

<div class="theconversation-article-body"> <p>“This video is not available in your location”. It’s a message familiar to many people trying to watch global content online. But beneath this frustration lies a deeper question – how do we navigate digital borders safely and ethically?</p> <p>As our digital lives expand, so too does our desire for access. Maybe you want to see the latest streaming shows before they arrive in your country. Maybe you’re a sports fan wanting to watch live broadcasts of international events. Or perhaps you need to log into your company’s secure intranet while at home or overseas.</p> <p>Enter the virtual private network (VPN) – a technology that’s become as essential as antivirus software for many. With many commercial and free VPN providers on the market, interest in these services <a href="https://www.comparitech.com/vpn/vpn-statistics/">has grown in recent years</a>.</p> <h2>How does a VPN work?</h2> <p>A <a href="https://computingaustralia.com.au/5-minute-helpdesk-what-is-a-vpn-and-why-should-i-use-one/">VPN</a> is like a secure tunnel between your device and the internet. When you use a VPN, your <a href="https://www.esafety.gov.au/key-topics/online-tools-and-features/encryption">internal traffic is scrambled into unreadable data</a> and routed through a remote server, which also masks your real IP address.</p> <p>Think of it like this: instead of sending a postcard with your return address, you send it in an envelope to a trusted friend overseas who mails it on your behalf. To anyone looking at the envelope, it looks like the message came from your friend and not you.</p> <p>This technique shields your identity, protects your data from snoopers, and tricks websites into thinking you are browsing from another location.</p> <p>While often marketed as <a href="https://www.le-vpn.com/australia-cyber-privacy-vpn/">tools for online privacy</a>, VPNs have grown popular for another reason: access.</p> <p>Many people use VPNs to access geo-blocked content, secure their internet activity, work remotely – <a href="https://www.cyber.gov.au/protect-yourself/staying-secure-online/security-tips-remote-working">especially when handling sensitive data</a> – and protect against online tracking and targeted advertising.</p> <h2>VPNs are legal, if a bit grey</h2> <p>VPN services are offered by dozens of providers globally. Companies such as NordVPN, ProtonVPN, ExpressVPN and Surfshark offer paid subscriptions with strong security guarantees. Free VPNs also exist but come with caveats (more on this in a moment).</p> <p>In <a href="https://us.norton.com/blog/privacy/are-vpns-legal">most countries</a>, including <a href="https://www.cyber.gov.au/protect-yourself/staying-secure-online/connecting-to-public-wi-fi">Australia</a>, using a VPN is completely legal.</p> <p>However, what makes it murky is what one might use it <em>for</em>. While using a VPN is legal, engaging in illegal activities while using one remains prohibited.</p> <p>Streaming services like Netflix or Disney+ license content by region. Using a VPN to access a foreign catalogue may violate their terms of service and potentially be grounds for account suspension.</p> <p>Australian law does not criminalise accessing geo-blocked content via VPN, but the copyright act does prohibit circumventing “technological protection measures” in certain cases.</p> <p>The grey area lies in enforcement. Technically, copyright law does ban getting around certain protections. However, the <a href="https://www.copyright.org.au/browse/book/ACC-Geoblocking%2C-VPNs-%26-Copyright-INFO127">latest advice does not mention</a> any cases where regular users have been taken to court for this kind of behaviour.</p> <p>So far, enforcement has mostly targeted websites and platforms that host or enable large-scale copyright infringement; not everyday viewers who want to watch a show a bit early.</p> <h2>Beware of ‘free’ VPNs</h2> <p>Not all VPNs are created equal. While premium services invest in strong encryption and privacy protections, free VPNs often make money by collecting user data – <a href="https://www.choice.com.au/electronics-and-technology/internet/connecting-to-the-internet/buying-guides/vpn-services">the very thing you may be trying to avoid</a>.</p> <p>Risks of unsafe VPNs include data leaks, injection of ads or trackers into your browsing, and malware and spyware, <a href="https://www.abc.net.au/news/2017-01-25/viruses-spyware-found-in-alarming-number-of-android-vpn-apps/8210796">especially in free mobile apps</a> that claim to provide a VPN service.</p> <p>Using a poorly designed or dishonest VPN is like hiring a bodyguard who sells your location. It might give the impression of safety, but you may actually be more vulnerable than before.</p> <h2>Okay, so how do I choose a VPN?</h2> <p>With so many VPNs available, both free and paid, it can be hard to know which one to trust. If you are considering a VPN, here are five things to look for.</p> <p><strong><a href="https://www.expressvpn.com/what-is-vpn/policy-towards-logs">No-log policy</a>.</strong> A trustworthy VPN should have a strict no-log policy, meaning it does not store any records of your internet activity, connection time or IP address. This ensures even if the VPN provider is hacked, subpoenaed or pressured by a government, they have nothing to hand over.</p> <p><strong>Strong encryption standards.</strong> Encryption is what makes your data unreadable to anyone snooping on your connection, such as hackers on public WiFi or your internet provider. A somewhat technical thing to look out for is <a href="https://www.kiteworks.com/risk-compliance-glossary/aes-256-encryption/">AES 256-bit encryption</a> – it’s extremely secure and is used by banks and governments.</p> <p><strong>Independent audits.</strong> Reliable VPN services <a href="https://vpncentral.com/nordvpn-reaffirms-no-log-claims-with-fifth-deloitte-audit/">voluntarily undergo third-party audits</a> to verify their privacy claims and the security of their infrastructure.</p> <p><strong>Kill switch.</strong> A kill switch is a critical safety feature that automatically blocks internet traffic if the VPN connection drops. This prevents your real IP address and data from being exposed, even momentarily.</p> <p><strong>Jurisdiction.</strong> VPNs are subject to the laws of the country they are based in. The countries in the <a href="https://cyberinsider.com/5-eyes-9-eyes-14-eyes/">Five Eyes intelligence alliance</a> (Australia, Canada, United Kingdom, United States and New Zealand) may legally compel providers to hand over user data. If a VPN service has a strict no-log policy and does not collect information about what you do online, then even under legal pressure, there is nothing to hand over. So, you are safe.</p> <p>In an era of growing surveillance, cybercrime and corporate data collection, VPNs are essential tools for reclaiming your online privacy and data.</p> <p>But like any tool, the effectiveness (and ethics) of VPNs depend on how you use them. Next time you fire up your VPN, ask yourself – am I just dodging a digital border, or actively protecting my online freedom?<!-- Below is The Conversation's page counter tag.

Technology

Most of us will leave behind a large ‘digital legacy’ when we die. Here’s how to plan what happens to it

<div class="theconversation-article-body"> <p>Imagine you are planning the funeral music for a loved one who has died. You can’t remember their favourite song, so you try to login to their Spotify account. Then you realise the account login is inaccessible, and with it has gone their personal history of Spotify playlists, annual “wrapped” analytics, and liked songs curated to reflect their taste, memories, and identity.</p> <p>We tend to think about inheritance in physical terms: money, property, personal belongings. But the vast volume of digital stuff we accumulate in life and leave behind in death is now just as important – and this “<a href="https://digitallegacyassociation.org">digital legacy</a>” is probably more meaningful.</p> <p>Digital legacies are increasingly complex and evolving. They include now-familiar items such as social media and banking accounts, along with our stored photos, videos and messages. But they also encompass virtual currencies, behavioural tracking data, and even AI-generated avatars.</p> <p>This digital data is not only fundamental to our online identities in life, but to our inheritance in death. So how can we properly plan for what happens to it?</p> <h2>A window into our lives</h2> <p>Digital legacy is commonly classified into two categories: <a href="https://www.esafety.gov.au/key-topics/digital-wellbeing/what-happens-to-your-digital-accounts-after-you-die">digital assets and digital presence</a>.</p> <p>Digital assets include items with economic value. For example, domain names, financial accounts, monetised social media, online businesses, virtual currencies, digital goods, and personal digital IP. Access to these is spread across platforms, hidden behind passwords or restricted by privacy laws.</p> <p>Digital presence includes content with no monetary value. However, it may have great personal significance. For example, our photos and videos, social media profiles, email or chat threads, and other content archived in cloud or platform services.</p> <p>There is also data that might not seem like content. It may not even seem to belong to us. This includes analytics data such as health and wellness app tracking data. It also includes behavioural data such as location, search or viewing history collected from platforms such as Google, Netflix and Spotify.</p> <p>This data reveals patterns in our preferences, passions, and daily life that can hold intimate meaning. For example, knowing the music a loved one listened to on the day they died.</p> <p>Digital remains now also include scheduled <a href="https://go-paige.com/memories/">posthumous messages</a> or <a href="https://www.hereafter.ai">AI-generated avatars</a>.</p> <p>All of this raises both practical and ethical questions about identity, privacy, and corporate power over our digital afterlives. Who has the right to access, delete, or transform this data?</p> <h2>Planning for your digital remains</h2> <p>Just as we prepare wills for physical possessions, we need to plan for our digital remains. Without clear instructions, important digital data may be lost and inaccessible to our loved ones.</p> <p>In 2017, I helped develop key recommendations for <a href="https://accan.org.au/files/Grants/Death%20and%20the%20Internet_2017-web.pdf">planning your digital legacy</a>. These include:</p> <ul> <li>creating an inventory of accounts and assets, recording usernames and login information, and if possible, downloading personal content for local storage</li> <li>specifying preferences in writing, noting wishes about what content should be preserved, deleted, or shared – and with whom</li> <li>using password managers to securely store and share access to information and legacy preferences</li> <li>designating a <a href="https://www.tonkinlaw.com/resources/digital-estate-planning-victoria-safeguarding-online-assets/">digital executor</a> who has legal authority to carry out your digital legacy wishes and preferences, ideally with legal advice</li> <li>using legacy features on available platforms, such as <a href="https://www.facebook.com/help/1070665206293088">Facebook’s Legacy Contact</a>, <a href="https://support.google.com/accounts/answer/3036546?hl=en">Google’s Inactive Account Manager</a>, or <a href="https://digital-legacy.apple.com">Apple’s Digital Legacy</a>.</li> </ul> <h2>What if your loved one left no plan?</h2> <p>These steps may sound uncontroversial. But digital wills remain uncommon. And without them, managing someone’s digital legacy can be fraught with legal and technical barriers.</p> <p>Platform terms of service and privacy rules often prevent access by anyone other than the account holder. They can also require official documentation such as a death certificate before granting limited access to download or close an account.</p> <p>In such instances, gaining access will probably only be possible through imperfect workarounds, such as searching online for traces of someone’s digital life, attempting to use account recovery tools, or scouring personal documents for login information.</p> <figure><iframe src="https://www.youtube.com/embed/WmQH27MNLz8?wmode=transparent&start=0" width="440" height="260" frameborder="0" allowfullscreen="allowfullscreen"></iframe></figure> <h2>The need for better standards</h2> <p>Current platform policies have clear limitations for handling digital legacies. For example, policies are inconsistent. They are also typically limited to memorialising or deleting accounts.</p> <p>With no unified framework, service providers often prioritise data privacy over family access. Current tools prioritise visible content such as profiles or posts. However, they exclude less visible yet equally valuable (and often more meaningful) behavioural data such as listening habits.</p> <p>Problems can also arise when data is removed from its original platform. For example, photos from Facebook can lose their social and relational meaning without their associated comment threads, reactions, or interactivity.</p> <p>Meanwhile, emerging uses of posthumous data, especially AI-generated avatars, raise urgent issues about digital personhood, ownership, and possible harms. These “digital remains” may be stored indefinitely on commercial servers without standard protocols for curation or user rights.</p> <p>The result is a growing tension between personal ownership and corporate control. This makes digital legacy not only a matter of individual concern but one of digital governance.</p> <p><a href="https://www.archivists.org.au/community/representation/standards-australias-committee-it-21-records-management-and-archives">Standards Australia</a> and the <a href="https://dcj.nsw.gov.au/news-and-media/media-releases-archive/2022/reform-to-allow-data-access-after-death.html">New South Wales Law Reform Commission</a> have recognised this. Both organisations are seeking <a href="https://lawreform.nsw.gov.au/documents/Current-projects/Digital%20assets/Preliminary%20submissions/PDI10.pdf">consultation</a> to develop frameworks that address inconsistencies in platform standards and user access.</p> <p>Managing our digital legacies demands more than practical foresight. It compels critical reflection on the infrastructures and values that shape our online afterlives.<!-- Below is The Conversation's page counter tag.

Why do some people need less sleep than others?

<div class="theconversation-article-body"> <p>Have you ever noticed how some people bounce out of bed after just a few hours of sleep, while others can barely function without a solid eight hours?</p> <p>Take Margaret Thatcher, for example. The former British prime minister was known for sleeping <a href="https://www.bbc.com/news/magazine-22084671">just four hours a night</a>. She worked late, rose early, and seemed to thrive on little sleep.</p> <p>But for most of us, that kind of sleep schedule would be disastrous. We’d be groggy, unfocused, and reaching for sugary snacks and caffeinated drinks by mid-morning.</p> <p>So why do some people seem to need less sleep than others? It’s a question that’s fascinated scientists for years. Here’s what we know so far.</p> <h2>Natural short sleepers</h2> <p>There is a small group of people who don’t need much sleep. We call them <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6879540/">natural short sleepers</a>. They can function perfectly well on just four to six hours of sleep each night, often for their entire lives.</p> <p>Generally they <a href="https://academic.oup.com/sleep/article/44/Supplement_2/A154/6260529">don’t feel tired</a>, they don’t nap, and they don’t suffer the usual negative consequences of sleep deprivation. Scientists call this the natural short sleep phenotype – a biological trait that allows people to get all the benefits of sleep in less time.</p> <p>In 2010 researchers discovered genetic mutations that help explain this phenomenon. Natural short sleepers carry rare variants <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2884988/">in certain genes</a>, which seem to make their sleep more efficient.</p> <p>More recently, a <a href="https://www.pnas.org/doi/epub/10.1073/pnas.2500356122">2025 study</a> assessed a woman in her 70s with one of these rare mutations. Despite sleeping just six hours a night for most of her life, she remained physically healthy, mentally sharp, and led a full, active life. Her body, it seems, was simply wired to need less sleep.</p> <p>We’re still learning about how common these genetic mutations are and why they occur.</p> <h2>Not everyone who sleeps less is a natural short sleeper</h2> <p>But here’s the catch: most people who think they’re natural short sleepers aren’t. They’re just chronically sleep-deprived. Often, their short sleep is due to long work hours, social commitments, or a belief sleeping less is a sign of strength or productivity.</p> <p>In today’s hustle culture, it’s common to hear people boast about getting by on only a few hours of sleep. But for the average person, that’s not sustainable.</p> <p>The effects of short sleep build up over time, creating what’s known as a “sleep debt”. This <a href="https://www.sciencedirect.com/science/article/pii/S0149763417301641">can lead to</a> poor concentration, mood swings, micro-sleeps (brief lapses into sleep), reduced performance and even <a href="https://www.sciencedirect.com/science/article/pii/S1389945716301381">long-term health risks</a>. For example, short sleep has been linked to an increased risk of obesity, diabetes, high blood pressure and cardiovascular disease (heart disease and stroke).</p> <h2>The weekend catch-up dilemma</h2> <p>To make up for lost sleep during the week, many people try to “catch up” on weekends.</p> <p>This can help repay some of the sleep debt that has accumulated in the short term. Research <a href="https://www.sciencedirect.com/science/article/pii/S2352721823001663?via%3Dihub">suggests</a> getting one to two extra hours of sleep on the weekend or taking naps when possible may help reduce the negative effects of short sleep.</p> <p>However, it’s not a perfect fix. Weekend catch-up sleep and naps may not fully resolve sleep debt. The topic remains one of ongoing scientific debate.</p> <p>A recent <a href="https://academic.oup.com/sleep/article/47/11/zsae135/7696120">large study</a> suggested weekend catch-up sleep may not offset the cardiovascular risks associated with chronic short sleep.</p> <p>What’s more, large swings in sleep timing can disrupt your body’s <a href="https://www.nature.com/articles/s41598-017-03171-4">internal clock</a>, and sleeping in too much on weekends may make it harder to fall asleep on Sunday night, which can mean starting the working week less rested.</p> <p>Increasing evidence indicates <a href="https://academic.oup.com/sleep/article/47/1/zsad253/7280269">repeated cycles of irregular sleep</a> may have an important influence on general health and the risk of early death, potentially even more so than how long we sleep for.</p> <p>Ultimately, while moderate catch-up sleep might offer some benefits, it’s no substitute for consistent, high-quality sleep throughout the week. That said, maintaining such regularity can be particularly challenging for people with non-traditional schedules, such as shift workers.</p> <h2>So, was Thatcher a true natural short sleeper?</h2> <p>It’s hard to say. Some reports suggest <a href="https://www.theguardian.com/lifeandstyle/2021/aug/27/from-aristotle-to-einstein-a-brief-history-of-power-nappers">she napped during the day</a> in the back of a car between meetings. That could mean she was simply sleep-deprived and compensating for an accumulated sleep debt when she could.</p> <p>Separate to whether someone is a natural short sleeper, there are a range of other reasons people may need more or less sleep than others. Factors <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">such as age</a> and underlying health conditions can significantly influence sleep requirements.</p> <p>For example, older adults often experience changes in their circadian rhythms and are more likely to suffer from fragmented sleep due to conditions <a href="https://link.springer.com/article/10.1007/s00702-019-02067-z">such as arthritis</a> or <a href="https://link.springer.com/article/10.1007/s11886-023-01939-x">cardiovascular disease</a>.</p> <p>Sleep needs vary from person to person, and while a lucky few can thrive on less, most of us need <a href="https://www.sleephealthfoundation.org.au/sleep-topics/how-much-sleep-do-you-really-need">seven to nine hours</a> a night to feel and function our best. If you’re regularly skimping on sleep and relying on weekends to catch up, it might be time to rethink your routine. After all, sleep isn’t a luxury – it’s a biological necessity.<!-- Below is The Conversation's page counter tag.

What is mantle cell lymphoma? Magda Szubanski’s ‘rare and fast-moving’ cancer explained

<div class="theconversation-article-body"><em><a href="https://theconversation.com/institutions/wehi-walter-and-eliza-hall-institute-of-medical-research-822"> </a></em>Beloved Australian actor Magda Szubanski has revealed she’s been diagnosed with a “very rare, very aggressive, very serious” blood cancer called mantle cell lymphoma.</p> <p>In a <a href="https://www.instagram.com/magda_szubanski/reel/DKOM_tZSuO2/">post on social media</a>, Szubanski said she would be starting treatment in a few weeks for the stage 4 cancer, which she called “one of the nasty ones, unfortunately”.</p> <p>So, what is mantle cell lymphoma? And how is it treated?</p> <h2>What is mantle cell lymphoma?</h2> <p>There are more than 100 subtypes of blood cancers, but they are commonly divided into one of two groups. These are <a href="https://medschool.ucla.edu/news-article/leukemia-vs-lymphoma-what-is-the-difference">based on</a> where they originate: leukaemias develop in the bone marrow, and lymphomas develop in the lymphatic system.</p> <p>Lymphomas develop from white blood cells (lymphocytes), which circulate in the blood and lymphatic system and help fight infection.</p> <p>You may not have heard of the <a href="https://cancer.ca/en/cancer-information/what-is-cancer/lymphatic-system">lymphatic system</a>, but it plays a key role in your immune response.</p> <p>The lymphatic circulatory system is responsible for transporting fluids (lymph) around your body. <a href="https://www.cancer.gov/publications/dictionaries/cancer-terms/def/lymph#:%7E:text=Listen%20to%20pronunciation,the%20body%20in%20lymph%20vessels.">Lymph</a> comes from blood plasma, and helps remove waste from your tissues.</p> <p>As part of the lymphatic system, tissues like the spleen and thymus help produce many of the immune cells you use to fight infections.</p> <p>These cells are then housed in specialised organs called lymph nodes – small pea-sized glands located throughout your body.</p> <p>Lymph nodes are kind of like the “war room” of your <a href="https://www.ncbi.nlm.nih.gov/books/NBK279395/">immune</a> <a href="https://www.ncbi.nlm.nih.gov/books/NBK279396/">system</a>.</p> <p>Your body contains hundreds of lymph nodes, and each contains millions of lymphocytes. These include the T and B cells – the main fighting cells in adaptive immunity.</p> <p>If B cells in an area of the lymph node known as the “<a href="https://www.lymphoma.org.au/types-of-lymphoma/non-hodgkin-lymphoma/aggressive-fast-growing-b-cell-nhl/mantle-cell-lymphoma-mcl/">mantle zone</a>” become cancerous, it is called mantle cell lymphoma.</p> <h2>How rare is it?</h2> <p>In 2020, <a href="https://www.aihw.gov.au/reports/cancer/cancer-data-in-australia/contents/blood-cancer-incidence-and-survival-by-histology-e">there were 330 cases</a> of mantle cell lymphoma diagnosed in Australia, accounting for a small fraction (5%) of lymphoma cases.</p> <p>Overall, lymphomas account for around <a href="https://www.canceraustralia.gov.au/cancer-types/lymphoma/lymphoma-australia-statistics">one in twenty</a> new cancer diagnoses. This makes mantle cell lymphoma quite rare.</p> <p>Mantle cell lymphoma is about <a href="https://www.aihw.gov.au/reports/cancer/cancer-data-in-australia/contents/blood-cancer-incidence-and-survival-by-histology-e">three times more common in men than in women</a>, and mostly affects people over the age of 60.</p> <h2>Is there a cure?</h2> <p>Unfortunately, mantle cell lymphoma is largely <a href="https://onlinelibrary.wiley.com/doi/full/10.1002/ajh.26523">considered incurable</a> with the therapies currently available.</p> <p>Like many cancers, mantle cell lymphoma can vary in how quickly it develops and its severity.</p> <p>As Szubanski’s cancer has been described as “fast-moving” and is already stage 4, it appears that it is a more serious case.</p> <p>Stage 4 is the most advanced stage – meaning the <a href="https://theconversation.com/how-does-cancer-spread-to-other-parts-of-the-body-219616">cancer has spread</a> (metastasised) to other tissues.</p> <p>Treatment at this stage can be more complicated than when the cancer is caught earlier. But treatment can still help people go on to live for many years.</p> <h2>What does treatment involve?</h2> <p>In her social media post, Szubanski said she will be receiving “one of the best treatments available (the Nordic protocol)”.</p> <p>This is one of the most common treatments for an aggressive lymphoma.</p> <p>The main component is “R-CHOP” – a <a href="https://www.cancer.gov/about-cancer/treatment/drugs/r-chop">combination therapy</a>. It involves a mixture of different drugs, including chemotherapy, to attack the cancer from multiple angles at the same time.</p> <p>Different strengths of the drugs can be used (the maximum strength is sometimes called R-maxi-CHOP).</p> <p>A stem cell transplantation may also be included in the regimen.</p> <p>How effective this treatment is will depend on many different factors, including the type and stage of the lymphoma.</p> <p>The aim is to kill as many cancer cells as possible, and therefore extend a patient’s life for as long as possible.</p> <p>Therapy also focuses on providing a high quality-of-life for patients.</p> <h2>How is it diagnosed?</h2> <p>Szubanski’s mantle cell lymphoma was detected during a breast cancer screen where, <a href="https://www.instagram.com/magda_szubanski/reel/DKOM_tZSuO2/">she says</a>, “they found my lymph nodes were up”.</p> <p>Imaging techniques, such as a mammogram or MRI, may detect tell-tale signs of lymphoma, such as swollen lymph nodes.</p> <p>However a biopsy – <a href="https://www.mayoclinic.org/diseases-conditions/cancer/in-depth/biopsy/art-20043922">a small sample of tissue from the affected area</a> – would then be required to confirm the presence of cancer cells and identify what type.</p> <p>Blood cancer symptoms can be vague, but it’s good to know what to look for.</p> <p>As well as swollen lymph nodes, <a href="https://www.leukaemia.org.au/blood-cancer/blood-cancer-signs-and-symptoms/">symptoms of lymphoma</a> include nausea, tiredness, loss of appetite, fevers, gastrointestinal issues, unexplained weight loss, and night sweats.</p> <p>If you have any concerns, you should consult a doctor.<!-- Below is The Conversation's page counter tag.

What’s the difference between ageing and frailty?

<div class="theconversation-article-body"> <p>Ageing is a normal part of the life course. It doesn’t matter how many green smoothies you drink, or how many “anti-ageing” skin care products you use, you can’t stop the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2685272/">ageing process</a>.</p> <p>But while we’re all getting older, not everyone who ages will necessarily become frail. Ageing and frailty are closely related, but they’re not the same thing.</p> <p>Let’s break down the difference between the two.</p> <h2>What is ageing?</h2> <p>On a biological level, ageing is the result of the build-up of <a href="https://www.who.int/news-room/fact-sheets/detail/ageing-and-health">cellular and molecular damage</a> in the body over time.</p> <p>The ageing process causes a gradual decline in physical and mental function, a higher risk of disease, and eventual (and unavoidable) death.</p> <p>Still, some people think they can cheat the system, <a href="https://fortune.com/well/article/bryan-johnson-live-longer-unrecognizable-anti-aging-procedure/">spending millions</a> trying to stay young forever. While we may be able to reduce the <a href="https://theconversation.com/do-these-three-popular-anti-ageing-skincare-ingredients-work-heres-what-the-evidence-says-182200">appearance of ageing</a>, ultimately there’s <a href="https://www.nature.com/articles/s44324-024-00040-3">no magic pill</a> to <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC2685272/">increase our longevity</a>.</p> <p>Around one in six Australians are over the age of 65 (<a href="https://www.aihw.gov.au/reports/older-people/older-australians/contents/demographic-profile">16% of the total population</a>). Yet <a href="https://www.tandfonline.com/doi/full/10.1080/03601277.2024.2402056">as individuals</a> and <a href="https://theconversation.com/fear-of-ageing-is-really-a-fear-of-the-unknown-and-modern-society-is-making-things-worse-220925">a society</a> many of us still have a <a href="https://www.smh.com.au/lifestyle/health-and-wellness/we-ve-been-constructed-to-think-a-certain-way-the-psychology-of-ageing-20231213-p5er6a.html">fear of ageing</a>.</p> <p>But what is it about ageing we are so afraid of? When it comes down to it, many people are probably less afraid of ageing, and more afraid of becoming frail.</p> <h2>What is frailty?</h2> <p><a href="https://www.afn.org.au/what-is-frailty/">Frailty</a> is defined as a state of vulnerability characterised by a loss of reserve across multiple parts of the body.</p> <p>Frailty is generally characterised by <a href="https://www1.racgp.org.au/newsgp/clinical/frailty-declared-a-medical-condition">several physical symptoms</a>, such as weakness, slow walking speed, exhaustion, unintentional weight loss, and low activity level.</p> <p>Lower bone density and osteoporosis (a condition where the bones become weak and brittle) are also <a href="https://josr-online.biomedcentral.com/articles/10.1186/s13018-024-04875-w">associated with frailty</a>, increasing the risk of <a href="https://www.sciencedirect.com/science/article/pii/S1279770723020250">falls and fractures</a>.</p> <p>Notably, someone who is frail is less able to “bounce back” (or recover) after a stressor event compared to someone who is not frail. A stressor event could be, for example, having a fall, getting a urinary infection, or even being admitted to hospital.</p> <p>Frailty is more common in older people. But in some cases, frailty can affect younger people too. For example, people with advanced chronic diseases, such as <a href="https://academic.oup.com/eurjcn/article/22/4/345/6775229">heart failure</a>, can <a href="https://onlinelibrary.wiley.com/doi/full/10.5694/mja15.00801">develop frailty</a> much younger.</p> <p>Frailty is dynamic. While it can get worse over time, in some cases <a href="https://www.sciencedirect.com/science/article/pii/S037851221830478X">frailty can also be reversed</a> or even prevented through health and lifestyle changes.</p> <p>For example, we know physical inactivity and a sedentary lifestyle can <a href="https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(19)31786-6/abstract">significantly increase a person’s risk</a> of becoming frail. On the flip side, evidence shows doing more exercise can <a href="https://pubmed.ncbi.nlm.nih.gov/36746389/">reduce frailty in older adults</a>.</p> <p>There are other lifestyle modifications we can make too. And the earlier we make these changes, the better.</p> <h2>Preventing frailty</h2> <p>Here are some <a href="https://youtu.be/41cMkvsaOOM">key things</a> you can do to <a href="https://www.self.com/story/how-to-avoid-frailty-old-age">help prevent frailty</a>:</p> <p><strong>1. Get moving</strong></p> <p>Exercise more, including resistance training (such as squats and lunges, or grab some stretchy resistance bands). Many of these sorts of exercises can be done at home. YouTube has some <a href="https://youtu.be/XDQo4wslr7I?si=FAoyHLDZgSG5AN1r">great resources</a>.</p> <p>You might also consider joining a gym, or asking your GP about seeing an accredited exercise physiologist or physiotherapist. Medicare <a href="https://www9.health.gov.au/mbs/fullDisplay.cfm?type=item&amp;q=10953&amp;qt=item">subsidies may be available</a> for these specialists.</p> <p>The <a href="https://www.health.gov.au/topics/physical-activity-and-exercise/physical-activity-and-exercise-guidelines-for-all-australians/for-older-australians-65-years-and-over">physical activity guidelines</a> for older Australians recommend at least 30 minutes of moderate intensity physical activity on most days or preferably every day.</p> <p>The guidelines also highlight the importance of incorporating different types of activities (such as resistance, balance or flexibility exercises) and reducing the time you spend sitting down.</p> <p><strong>2. Stay socially active</strong></p> <p>Social isolation and loneliness can <a href="https://academic.oup.com/gerontologist/article-abstract/64/10/gnae114/7734069">contribute to the progression of frailty</a>. Reach out to friends and family for support or contact local community groups that you may be able to join. This might include your local Zumba class or bridge club.</p> <p><strong>3. Ask your doctor or pharmacist to regularly check your medications</strong></p> <p>“Polypharmacy” (when someone is prescribed <a href="https://www.safetyandquality.gov.au/our-work/healthcare-variation/fourth-atlas-2021/medicines-use-older-people/61-polypharmacy-75-years-and-over">five or more medications</a>) is associated with an increased <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6005607/">risk of frailty</a>. The presence of frailty can also interfere with how the <a href="https://www.sciencedirect.com/science/article/pii/S0047637419300387">body absorbs medicines</a>.</p> <p><a href="https://www.healthdirect.gov.au/home-medicines-review">Home medicine reviews</a> are available for older adults with a <a href="https://www9.health.gov.au/mbs/fullDisplay.cfm?type=item&amp;q=900">chronic medical condition or a complex medication regimen</a>.

Eat a protein-rich diet with plenty of fruit and vegetables</strong></p> <p><a href="https://academic.oup.com/biomedgerontology/article/61/6/589/589472?login=true#9578331">Low nutrient intake</a> can negatively impact physical function and may increase your risk of becoming frail. There’s some evidence to suggest eating more protein may <a href="https://academic.oup.com/ageing/article/49/1/32/5618813">delay the onset of frailty</a>.</p> <p>A food-first approach is best when looking to increase the <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC7598653/#:%7E:text=Many%20studies%20have%20described%20an,are%20necessary%20to%20prevent%20frailty.">protein in your diet</a>.

What makes somebody a narcissist?

<div class="theconversation-article-body"> <p>Narcissism has become the armchair diagnosis of the decade. Social media is awash with people flinging the label around. Everyone’s ex seems to be a narcissist, some of our parents are under suspicion, and that office villain? They definitely tick the box, too.</p> <p>The accuracy of these rampant diagnoses warrants scepticism. But the reality is narcissists do exist. At its extreme, narcissism is a rare mental health diagnosis, known as <a href="https://www.ncbi.nlm.nih.gov/books/NBK556001/">narcissistic personality disorder</a>. But narcissism also describes a cluster of personality traits, which we all display to varying degrees.</p> <p>For those of us who have been in close quarters with someone high in narcissistic traits, we rarely walk away unscathed. And we may be left with lingering questions. For example, what made them this way?</p> <p>In a recent <a href="https://doi.org/10.1016/j.paid.2025.113255">meta-analysis</a>, my colleagues and I pulled together studies examining the link between narcissism and adult attachment styles. Our findings offer an important clue – especially when it comes to the potential roots of vulnerable narcissism.</p> <h2>Types of narcissism</h2> <p>There are two main types of <a href="https://doi.org/10.1111/j.1467-6494.2010.00711.x">narcissism</a>.</p> <p>Grandiose narcissism is what typically comes to mind. It is characterised by an overtly grandiose, aggressive and dominant interpersonal style. In contrast, vulnerable narcissism is marked by introversion, hypersensitivity to criticism, and a defensive, insecure grandiosity that masks fragile self-esteem.</p> <p>Antagonistic traits such as entitlement, manipulation, and a lack of empathy lie at the core of both narcissism types. This helps to explain the <a href="https://doi.org/10.1037/abn0000298">interpersonal difficulties</a> linked to each.</p> <p>Vulnerable narcissism, in particular, has been linked to a range of harmful behaviours in romantic relationships. Individuals high in this trait are more likely to engage in <a href="https://www.respectvictoria.vic.gov.au/news/red-flags-what-love-bombing-and-why-it-bad">love bombing</a>, <a href="https://doi.org/10.1016/j.tele.2023.101985">ghosting and breadcrumbing</a>.</p> <p>They also tend to report <a href="https://doi.org/10.1080/15298868.2019.1707272">lower relationship satisfaction</a>, hold more permissive attitudes towards <a href="https://doi.org/10.1037/fam0001126">infidelity</a> and perpetrate <a href="https://doi.org/10.1177/15248380231196115">intimate partner violence</a> at higher rates.</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/DIyj175t6iV/?utm_source=ig_embed&utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DIyj175t6iV/?utm_source=ig_embed&utm_campaign=loading" target="_blank" rel="noopener">A post shared by Amanda E. White, LPC, LMHC (@therapyforwomen)</a></p> </div> </blockquote> <h2>Secure versus insecure attachment</h2> <p>Researchers have turned to <a href="https://theconversation.com/attachment-theory-what-people-get-wrong-about-pop-psychologys-latest-trend-for-explaining-relationships-195034">attachment styles</a> to help explain how individuals high in narcissism behave in romantic relationships.</p> <p><a href="https://doi.org/10.1002/9781118938119.ch2">Attachment theory</a> proposes that early experiences with primary caregivers shape our beliefs about ourselves and others. These beliefs are thought to persist into adulthood and influence how we experience and navigate adult relationships.</p> <p>If we felt safe, loved and supported as children, we are more likely to have a positive view of our self and others. This is the hallmark of secure attachment, which lays the foundation for healthy, stable relationships in adulthood.</p> <p>But when early relationships are marked by neglect, inconsistency or abuse, they can give rise to insecure attachment styles. <a href="https://psycnet.apa.org/record/1991-33075-001">Adult attachment models</a> generally identify three types of insecure attachment.</p> <p>Preoccupied attachment develops from a negative view of the self and a positive view of others. Individuals with this style often feel unworthy of love and seek constant reassurance in relationships, fearing rejection and abandonment.</p> <p>Dismissive attachment is rooted in a positive view of the self but a negative view of others. These individuals tend to prioritise independence over intimacy. As a result, they often struggle to form deep connections.</p> <p>Fearful attachment involves negative views of both the self and others. Those with this style typically crave connection while at the same time fearing it, leading to push-pull dynamics in relationships.</p> <h2>An interesting pattern</h2> <p>In our meta-analysis, we combined the results of 33 previous studies comprising more than 10,000 participants to examine how narcissism relates to each of the four adult attachment styles. Overall, narcissism was linked to each of the three insecure attachment styles.</p> <p>But when we looked at the two types of narcissism separately, an interesting pattern emerged. Vulnerable narcissism was consistently linked to insecure attachment styles – with associations of moderate strength for preoccupied and fearful attachment styles.</p> <p>In contrast, grandiose narcissism showed no such link.</p> <p>Does this mean insecure attachment causes vulnerable narcissism? Not necessarily. The studies we reviewed were “correlational”, which means they looked at connections, not causes. So we can’t say attachment styles cause vulnerable narcissism. To answer that, we’d need longitudinal research tracking people over time.</p> <p>Still, our findings suggest that insecure attachment – particularly preoccupied and fearful attachment styles – may be an important risk factor in the development of vulnerable narcissism.</p> <p>Of course, not everyone with an insecure attachment style has high levels of vulnerable narcissism. However, for some, vulnerable narcissism may emerge as a defensive coping strategy that arises when early attachments were marked by inconsistency, neglect or abuse.</p> <h2>Healing childhood wounds</h2> <p>Attachment styles tend to be <a href="https://doi.org/10.1207/S15327957PSPR0602_03">fairly consistent throughout a person’s life</a>, however change is possible. Attachment-focused therapies, such as <a href="https://theconversation.com/im-a-failure-how-schema-therapy-tackles-the-deep-rooted-beliefs-that-affect-our-mental-health-250789">schema therapy</a> and <a href="https://www.psychologytoday.com/au/therapy-types/emotionally-focused-therapy">emotionally focussed therapy</a>, can help individuals heal attachment wounds and build more secure relationship patterns.

RBA cuts interest rate - so what happens now?

<div class="theconversation-article-body"> <p>The Reserve Bank of Australia <a href="https://www.rba.gov.au/media-releases/2025/mr-25-13.html">cut the official interest rate</a> for the second time this year, as it lowered forecasts for Australian economic growth and pointed to increasing uncertainty in the world economy.</p> <p>The bank lowered the <a href="https://www.rba.gov.au/cash-rate-target-overview.html">cash rate target</a> by 0.25%, from 4.1% to 3.85%, saying inflation is expected to remain in the target band.</p> <p>All the big four banks swiftly passed the cut on to households with mortgages. This will save a household with a $500,000 loan about $80 a month.</p> <p>Announcing the cut, the Reserve Bank <a href="https://www.rba.gov.au/media-releases/2025/mr-25-13.html">stressed</a> in its accompanying statement it stands ready to reduce rates again if the economic outlook deteriorates sharply.</p> <blockquote> <p>The Board considered a severe downside scenario and noted that monetary policy is well placed to respond decisively to international developments if they were to have material implications for activity and inflation in Australia.</p> </blockquote> <h2>Inflation is back under control</h2> <p>The latest <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/consumer-price-index-australia/latest-release">Consumer Price Index</a> showed that inflation remained around the middle of the Reserve Bank’s <a href="https://www.rba.gov.au/education/resources/explainers/australias-inflation-target.html">medium-term target band of 2-3%</a> in the March quarter.</p> <p>The Reserve Bank was also comforted by the underlying inflation measure called the “trimmed mean”. This measure excludes items with the largest price movements up or down.</p> <p>The bank noted that it has returned to the 2–3% target band for the first time since 2021. This suggests inflation is not just temporarily low due to temporary factors such as the electricity price rebates.</p> <p><iframe id="QQ6io" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/QQ6io/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>In February, Reserve Bank Governor Michele Bullock <a href="https://parlinfo.aph.gov.au/parlInfo/download/committees/commrep/28670/toc_pdf/Economics%20Committee_2025_02_21_Official.pdf;fileType=application%2Fpdf">conceded</a> the bank had arguably been “late raising interest rates on the way up”. It did not want to be late on the way down.</p> <p>Perhaps Bullock is being unduly modest. The central bank looks to have judged well the extent of monetary tightening. It did not raise interest rates as much as its peers, but still got inflation back to the target.</p> <p><iframe id="ZIcUE" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/ZIcUE/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <h2>Unemployment remains low</h2> <p>Last week, we got an <a href="https://www.abs.gov.au/statistics/labour/employment-and-unemployment/labour-force-australia/latest-release">update</a> on the strength of the labour market. Unemployment stayed at 4.1%. It has now been around 4% since late 2023, a remarkable achievement.</p> <p>This is below the 4.5% the Reserve Bank had <a href="https://www.rba.gov.au/speeches/2019/sp-ag-2019-06-12-2.html">regarded</a> as the level consistent with steady inflation (in economic jargon, the <a href="https://www.rba.gov.au/education/resources/explainers/nairu.html">NAIRU</a>). But neither prices nor <a href="https://www.abs.gov.au/statistics/economy/price-indexes-and-inflation/wage-price-index-australia/latest-release">wages</a> have accelerated.</p> <p><iframe id="WYjUU" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/WYjUU/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <h2>Households and businesses may turn cautious</h2> <p>In its updated <a href="https://www.rba.gov.au/publications/smp/2025/may/pdf/statement-on-monetary-policy-2025-05.pdf">forecasts</a>, the bank sees headline inflation dropping to 2.1% by mid-year but going back to 3.0% by the end of the year, as the electricity subsidies are removed. By mid-2027, it will be back near the middle of the 2-3% target.</p> <p>Underlying inflation is forecast to stay around the middle of the target band throughout.</p> <p>The Reserve Bank cut its forecast for gross domestic product (GDP) to 2.1% by December, down from its previous forecast of 2.4% made in February. It said:</p> <blockquote> <p>Economic policy uncertainty has increased sharply alongside recent global developments, and this is expected to prompt some households to increase their precautionary savings and some businesses to postpone some investment decisions.</p> </blockquote> <p>The unemployment rate is expected to increase to 4.3% by the end of the year and remain there through 2026.</p> <p>Cost of living pressures look set to ease, as real household disposable income grows faster than population.</p> <p>As the Reserve Bank governor told a media conference on Tuesday:</p> <blockquote> <p>There’s now a new set of challenges facing the economy, but with inflation declining and the unemployment rate relatively low, we’re well positioned to deal with them. The board remains prepared to take further action if that is required.</p> </blockquote> <h2>Economic and policy ‘unpredictability’</h2> <p>The main uncertainty in the global economy is how the trade war instigated by US President Donald Trump will play out. <a href="https://www.washingtonpost.com/business/2025/05/14/trump-tariffs-china-trade/">According to one count</a>, he has announced new or revised tariff policies about 50 times.</p> <p>“The outlook for the global economy has deteriorated since the February statement. This is due to the adverse impact on global growth from higher tariffs and widespread economic and policy unpredictability,” the bank noted.</p> <p>The US tariff pauses on the highest rates on China and most other nations are due to be in place for 90 days. But more measures may be announced before then.</p> <p>This uncertainty is likely to be stifling trade, and even more so investment decisions by companies in the face of rapidly changing policies. And it will weaken the global economy.</p> <p>In her <a href="https://rba.livecrowdevents.tv/MediaConferenceMonetaryPolicyDecision20May2025/stream">press conference</a>, Bullock said the board’s judgement was that “global trade developments will overall be disinflationary for Australia”. Not only is the global outlook weaker, but some goods no longer being sold to the US could be diverted to Australia.</p> <h2>Where will interest rates go from here?</h2> <p>The Reserve Bank’s updated <a href="https://www.rba.gov.au/publications/smp/2025/may/pdf/statement-on-monetary-policy-2025-05.pdf">forecasts</a> assume interest rates will fall further, to 3.4% by the end of the year.</p> <p>But this is just a reflection of what <a href="https://www.rba.gov.au/statistics/cash-rate/assumptions/index.html">financial markets are implying</a>. It is not necessarily what the bank itself <em>expects</em> to do. It is certainty not a <em>promise</em> of what they will do.</p> <p>But the Reserve Bank still regards its stance as “restrictive”, or weighing on growth. So if it continues to believe inflation will stay within the target band, or the global outlook deteriorates, it will cut rates further.<!-- Below is The Conversation's page counter tag.

Why do some people get a curved back as they age and what can we do to avoid it?

<div class="theconversation-article-body"> <p>As we age, it’s common to notice posture changes: shoulders rounding, head leaning forward, back starting to curve. You might associate this with older adults and wonder: will this happen to me? Can I prevent it?</p> <p>It’s sometimes called “hunchback” or “roundback”, but the medical term for a curved back is kyphosis.</p> <p>When the curve is beyond what’s considered normal (greater than 40 degrees), we refer to this as hyperkyphosis. In more <a href="https://www.jospt.org/doi/10.2519/jospt.2010.3099#_i12:%7E:text=gold%2Dstandard%20radiograph.-,Clinical%20Consequences%20of%20Hyperkyphosis,-Functional%20Limitations">severe cases</a>, it may lead to pain, reduced mobility and physical function, or lower quality of life.</p> <p>Here’s how it happens, and how to reduce your risk.</p> <h2>What causes a curved back?</h2> <p>A healthy spine has an elongated s-shape, so a curve in the upper spine is completely normal.</p> <p>But when that curve becomes exaggerated and fixed (meaning you can’t stand up straight even if you try), it can signal a problem.</p> <p>One common cause of a curved back is poor posture. This type, called postural kyphosis, usually develops over time due to muscle imbalances, particularly in younger people who spend hours:</p> <ul> <li>hunched over a desk</li> <li>slouched in a chair, or</li> <li>looking down at a phone.</li> </ul> <p>Fortunately, this kind of curved back is often reversible with the right exercises, stretches and posture awareness.</p> <p>Older adults often develop a curved back, known as age-related kyphosis or hyperkyphosis.</p> <p>This is usually due to wear and tear in the spine, including vertebral compression fractures, which are tiny cracks in the bones of the spine (vertebrae).</p> <p>These cracks are most often caused by osteoporosis, a condition that makes bones more fragile with age.</p> <p>In these cases, it’s not just bad posture – it’s a structural change in the spine.</p> <h2>How can you tell the difference?</h2> <p>Signs of age-related hyperkyphosis include:</p> <ul> <li>your back curves even when you try to stand up straight</li> <li>back pain or stiffness</li> <li>a loss of height (anything greater than 3-4 centimetres compared to your peak adult height may be considered outside of “normal” ageing).</li> </ul> <p>Other causes of a curved back include:</p> <ul> <li><a href="https://pubmed.ncbi.nlm.nih.gov/30407981/">Scheuermann’s kyphosis</a> (which often develops during adolescence when the bones in the spine grow unevenly, leading to a forward curve in the upper back)</li> <li><a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC4347150/">congenital kyphosis</a> (a rare condition present from birth, caused by improper formation of the spinal bones. It can result in a more severe, fixed curve that worsens as a child grows)</li> <li>scoliosis (where the spine curves sideways into a c- or s-shape when viewed from behind), and</li> <li>lordosis (an excessive inward curve in the lower back, when viewed from the side).</li> </ul> <p>In addition to these structural conditions, arthritis, and in rare cases, spinal injuries or infections, can also play a role.</p> <h2>Should I see a doctor about my curved back?</h2> <p>Yes, especially if you’ve noticed a curve developing, have ongoing back pain, or have lost height over time.</p> <p>These can be signs of vertebral fractures, which can occur in the absence of an obvious injury, and are often painless.</p> <p>While one in five older adults have a vertebral fracture, as many as two-thirds of these fractures are <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002934315010128?casa_token=DzXngmS6GIoAAAAA:3ub0V4PuHbKjrqO9xYDo8vx2m9k6tbOtmz4yIVzkQvH-VylhgO_KnKaTYDLXpiHc9_4Jz0iNdQ">not diagnosed and treated</a>.</p> <p>In Australia, the Royal Australian College of General Practitioners and Healthy Bones Australia <a href="https://healthybonesaustralia.org.au/wp-content/uploads/2022/12/oa-racgp-osteoporosis-clinical-guidelines-2nd-ed.pdf">recommend</a> a spine x-ray for:</p> <ul> <li>people with kyphosis</li> <li>height loss equal to or more than 3 centimetres, or</li> <li>unexplained back pain.</li> </ul> <h2>What can I do to reduce my risk?</h2> <p>If you’re young or middle-aged, the habits you build today matter.</p> <p>The best way to prevent a curved back is to keep your bones strong, muscles active, and posture in check. That means:</p> <ul> <li>doing regular resistance training, especially targeting upper back muscles</li> <li>staying physically active, aiming for at least <a href="https://www.who.int/initiatives/behealthy/physical-activity">150 minutes per week</a></li> <li>getting enough protein, calcium, and vitamin D to support bone and muscle health</li> <li>avoiding smoking and limiting alcohol to reduce risk factors that worsen bone density and overall wellbeing</li> </ul> <p>Pay attention to your posture while sitting and standing. Position your head over your shoulders and shoulders over your hips. This reduces strain on your spine.</p> <h2>What exercises help prevent and manage a curved back?</h2> <p>Focus on <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5112023/">exercises that strengthen the muscles</a> that support an upright posture, particularly the upper back and core, while improving mobility in the chest and shoulders.</p> <p>In general, you want to prioritise extension-based movements. These involve straightening or lifting the spine and pulling the shoulders back.</p> <p>Repeated forward-bending (or flexion) movements may make things worse, especially in people with osteoporosis or spinal fractures.</p> <p>Good exercises include:</p> <ul> <li>back extensions (gently lift your chest off the floor while lying face down)</li> <li>resistance exercises targeting the muscles between your shoulder blades</li> <li>weight-bearing activities (such as brisk walking, jogging, stair climbing, or dancing) to keep bones strong and support overall fitness</li> <li>stretching your chest and hip flexors to open your posture and relieve tightness.</li> </ul> <p>Flexibility and balance training (such as yoga and pilates) can be <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC3700806/">beneficial</a>, particularly for posture awareness, balance, and mobility. But <a href="https://pubmed.ncbi.nlm.nih.gov/31034509/">research</a> increasingly supports muscle strengthening as the cornerstone of prevention and management.</p> <p>Muscle strengthening exercises, such as weight lifting or resistance training, reduces spinal curvature while enhancing muscle and bone mass.</p> <p>If you suspect you have kyphosis or already have osteoporosis or a vertebral fracture, consult a health professional before starting an exercise program. There may be some activities to avoid.</p> <h2>Can a curved back be reversed?</h2> <p>If it’s caused by poor posture and muscle weakness, then yes, it’s possible.</p> <p>But if it’s caused by bone changes, especially vertebral fractures, then full reversal is unlikely. However, treatment can reduce pain, improve function, and slow further progression.</p> <p>Protecting your posture isn’t just about appearance. It’s about staying strong, mobile and independent as you age.<!-- Below is The Conversation's page counter tag.

What is a blood cholesterol ratio? And what should yours be?

<div class="theconversation-article-body"> <p>Have you had a blood test to check your cholesterol level? These check the different blood fat components:</p> <ul> <li>total cholesterol</li> <li>LDL (low-density lipoprotein), which is sometimes called “bad cholesterol”</li> <li>HDL (high-density lipoprotein), which is sometimes called “good cholesterol”</li> <li>triglycerides.</li> </ul> <p>Your clinician then compares your test results to normal ranges – and may use ratios to compare different types of cholesterol.</p> <p><iframe id="8KC9s" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/8KC9s/6/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <p>High blood cholesterol is a major risk factor for cardiovascular disease. This is a broad term that includes disease of blood vessels throughout the body, arteries in the heart (known as coronary heart disease), heart failure, heart valve conditions, arrhythmia and stroke.</p> <p>So what does cholesterol do? And what does it mean to have a healthy cholesterol ratio?</p> <h2>What are blood fats?</h2> <p>Cholesterol is a waxy type of fat made in the liver and gut, with a small amount of pre-formed cholesterol coming from food.</p> <p>Cholesterol is found in all cell membranes, contributing to their structure and function. Your body <a href="https://www.ncbi.nlm.nih.gov/books/NBK513326/">uses cholesterol to make</a> vitamin D, bile acid, and hormones, including oestrogen, testosterone, cortisol and aldosterone.</p> <p>When there is too much cholesterol in your blood, it gets deposited into artery walls, making them hard and narrow. This process is called <a href="https://en.wikipedia.org/wiki/Atherosclerosis">atherosclerosis</a>.</p> <p>Cholesterol is <a href="https://www.ncbi.nlm.nih.gov/books/NBK513326/">packaged with</a> <a href="https://en.wikipedia.org/wiki/Triglyceride">triglycerides</a> (the most common type of fat in the body) and specific <a href="https://en.wikipedia.org/wiki/Apolipoprotein">“apo” proteins</a> into “lipo-proteins” as a package called “very-low-density” lipoproteins (VLDLs).</p> <p>These are transported via the blood to body tissue in a form called low-density lipoprotein (LDL) cholesterol.</p> <p>Excess cholesterol can be transported back to the liver by high-density lipoprotein, the HDL, for removal from circulation.</p> <p>Another less talked about blood fat is Lipoprotein-a, or Lp(a). This is determined by your genetics and <a href="https://www.victorchang.edu.au/heart-disease/high-cholesterol">not influenced by lifestyle factors</a>. About one in five (<a href="https://www1.racgp.org.au/ajgp/2021/may/lipid-management-and-implications-for-australian-g">20%</a>) of Australians are carriers.</p> <p>Having a high Lp(a) level is an independent cardiovascular disease risk factor.</p> <h2>Knowing your numbers</h2> <p>Your blood fat levels <a href="https://www.heartfoundation.org.au/your-heart/high-blood-cholesterol">are affected by</a> both modifiable factors:</p> <ul> <li>dietary intake</li> <li>physical activity</li> <li>alcohol</li> <li>smoking</li> <li>weight status.</li> </ul> <p>And non-modifiable factors:</p> <ul> <li>age</li> <li>sex</li> <li>family history.</li> </ul> <p><iframe id="S7Xp4" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/S7Xp4/1/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <h2>What are cholesterol ratios?</h2> <p>Cholesterol ratios are sometimes used to provide more detail on the balance between different types of blood fats and to evaluate risk of developing heart disease.</p> <p>Commonly used ratios include:</p> <h2>1. Total cholesterol to HDL ratio</h2> <p>This ratio is used in Australia to <a href="https://www.cvdcheck.org.au/calculator">assess risk of heart disease</a>. It’s calculated by dividing your total cholesterol number by your HDL (good) cholesterol number.</p> <p>A higher ratio (<a href="https://www.medicalnewstoday.com/articles/cholesterol-ratio-calculator#how-to-calculate">greater than 5</a>) is associated with a higher risk of heart disease, whereas a lower ratio is associated with a lower risk of heart disease.</p> <p>A <a href="https://pubmed.ncbi.nlm.nih.gov/36589799/">study</a> of 32,000 Americans over eight years found adults who had either very high, or very low, total cholesterol/HDL ratios were at 26% and 18% greater risk of death from any cause during the study period.</p> <p>Those with a ratio of greater than 4.2 had a 13% higher risk of death from heart disease than those with a ratio lower than 4.2.</p> <h2>2. Non-HDL cholesterol to HDL cholesterol ratio (NHHR)</h2> <p>Non-HDL cholesterol is the total cholesterol minus HDL. Non-HDL cholesterol includes all blood fats such as LDL, triglycerides, Lp(a) and others. This ratio is abbreviated as NHHR.</p> <p>This ratio has been used more recently because it compares the ratio of “bad” blood fats that can contribute to atherosclerosis (hardening and narrowing of the arteries) to “good” or anti-atherogenic blood fats (HDL).</p> <p>Non-HDL cholesterol is a <a href="https://pubmed.ncbi.nlm.nih.gov/31170997/">stronger predictor of cardiovascular disease risk</a> than LDL alone, while <a href="https://pubmed.ncbi.nlm.nih.gov/37228232/">HDL is associated with</a> lower cardiovascular disease risk.</p> <p>Because this ratio removes the “good” cholesterol from the non-HDL part of the ratio, it is not penalising those people who have really high amounts of “good” HDL that make up their total cholesterol, which the first ratio does.</p> <p>Research has suggested this ratio may be a stronger <a href="https://pubmed.ncbi.nlm.nih.gov/39949279/">predictor of atherosclerosis in women than men</a>, however more research is needed.</p> <p>Another <a href="https://pubmed.ncbi.nlm.nih.gov/39415313">study</a> followed more than 10,000 adults with type 2 diabetes from the United States and Canada for about five years. The researchers found that for each unit increase in the ratio, there was around a 12% increased risk of having a heart attack, stroke or death.</p> <p>They identified a risk threshold of 6.28 or above, after adjusting for other risk factors. Anyone with a ratio greater than this is at very high risk and would require management to lower their risk of heart disease.</p> <h2>3. LDL-to-HDL cholesterol ratio</h2> <p>LDL/HDL is calculated by dividing your LDL cholesterol number by the HDL number. This gives a ratio of “bad” to “good” cholesterol.</p> <p>A lower ratio (<a href="https://www.medicalnewstoday.com/articles/cholesterol-ratio-calculator#how-to-calculate">ideal is less than 2.0</a>) is associated with a lower risk of heart disease.</p> <p>While there is lesser focus on LDL/HDL, these ratios have been shown to be predictors of occurrence and <a href="https://pubmed.ncbi.nlm.nih.gov/35843962/">severity of heart attacks</a> in patients presenting with chest pain.</p> <p>If you’re worried about your cholesterol levels or cardiovascular disease risk factors and are aged 45 and over (or over 30 for First Nations people), consider seeing your GP for a Medicare-rebated <a href="https://www.heartfoundation.org.au/your-heart/heart-health-checks">Heart Health Check</a>.<!-- Below is The Conversation's page counter tag.

"It's simple": Sussan Ley reveals stance on Welcome to Country

<p>Newly elected Liberal leader <a href="https://oversixty.com.au/finance/legal/sussan-ley-elected-first-female-leader-of-the-liberal-party" target="_blank" rel="noopener">Sussan Ley </a>has called on her party to modernise and reconnect with contemporary Australian values following one of its worst electoral defeats in history.</p> <p>In her first press conference since defeating Angus Taylor for the leadership, Ms Ley pledged a fresh approach to politics, saying the Liberal Party must "respect, reflect, and represent modern Australia".</p> <p>“We have to meet the people where they are. And that’s what I am committed to doing and what I am determined to do,” she said. “I want to do things differently, and we have to have a fresh approach.”</p> <p>Ley described her election to the party’s top job as an “enormous privilege”, adding: “I am humbled. I am honoured. And I am up for the job.”</p> <p>The leadership transition follows a bruising election campaign that saw the Liberals suffer significant losses, prompting calls for renewal and deeper engagement with a changing electorate.</p> <p>Cultural recognition also emerged as a flashpoint during the campaign’s final days, with controversy over audience reactions to Welcome to Country ceremonies. Addressing the issue head-on, Ms Ley called for authenticity in cultural acknowledgements.</p> <p>“With respect to Welcome to Country, it’s simple: if it’s meaningful, if it matters, if it resonates, then it’s in the right place,” she said. “If it is done in a way that is ticking a box on a Teams meeting then I don’t think it is relevant. It actually diminishes the value of what it is.”</p> <p>On the issue of national symbols, Ms Ley said she frequently stands in front of the Indigenous flag but would prefer to see Australians united under a single banner.</p> <p>“We should unite under the one Australian flag, that is my firm view,” she stated.</p> <p>Ms Ley now faces the challenge of steering a divided and diminished Liberal Party toward renewal, with pressure mounting to appeal to a broader, more diverse Australia. Her leadership marks a potential turning point for the party as it seeks to rebuild and redefine its identity in opposition.</p> <p><em>Image: Instagram</em></p>

What is grounding and can it improve your sleep?

<div class="theconversation-article-body">Have you ever felt an unexpected sense of calm while walking barefoot on grass? Or noticed your stress begin to fade as you stood ankle deep in the ocean? If so, you may have unknowingly “grounded” yourself to the earth.</p> <p>Grounding, <a href="https://www.sciencedirect.com/science/article/pii/S2319417022001573">also known as earthing</a>, is the practice of making direct physical contact with the Earth’s surface. Our ancestors embraced this trend without knowing it. But with the invention of indoor homes, footpaths, roads, and even shoes, we have become <a href="https://onlinelibrary.wiley.com/doi/10.1155/2012/291541">less physically connected with the earth</a>.</p> <p>Grounding has been suggested to have <a href="https://www.healthline.com/health/grounding">a number of benefits</a>, such as improving mood, and reducing stress and pain. But overall, there’s limited conclusive evidence on the benefits of grounding.</p> <p>Somewhat ironically, the concept of grounding in 2025 is heavily influenced by technology, rather than getting out into nature. Consumers are being hit with social media reels promoting a range of technologies that ground us, and improve our health.</p> <p>Among the most common are promises of improved sleep with the use of a grounding sheet or mat. But is this just another TikTok trend, or could these products really help us get a better night’s sleep?</p> <blockquote class="instagram-media" style="background: #FFF; border: 0; border-radius: 3px; box-shadow: 0 0 1px 0 rgba(0,0,0,0.5),0 1px 10px 0 rgba(0,0,0,0.15); margin: 1px; max-width: 540px; min-width: 326px; padding: 0; width: calc(100% - 2px);" data-instgrm-captioned="" data-instgrm-permalink="https://www.instagram.com/reel/DHne7CasELA/?utm_source=ig_embed&amp;utm_campaign=loading" data-instgrm-version="14"> <div style="padding: 16px;"> <div style="display: flex; flex-direction: row; align-items: center;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 40px; margin-right: 14px; width: 40px;"> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 100px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 60px;"> </div> </div> </div> <div style="padding: 19% 0;"> </div> <div style="display: block; height: 50px; margin: 0 auto 12px; width: 50px;"> </div> <div style="padding-top: 8px;"> <div style="color: #3897f0; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: 550; line-height: 18px;">View this post on Instagram</div> </div> <div style="padding: 12.5% 0;"> </div> <div style="display: flex; flex-direction: row; margin-bottom: 14px; align-items: center;"> <div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(0px) translateY(7px);"> </div> <div style="background-color: #f4f4f4; height: 12.5px; transform: rotate(-45deg) translateX(3px) translateY(1px); width: 12.5px; flex-grow: 0; margin-right: 14px; margin-left: 2px;"> </div> <div style="background-color: #f4f4f4; border-radius: 50%; height: 12.5px; width: 12.5px; transform: translateX(9px) translateY(-18px);"> </div> </div> <div style="margin-left: 8px;"> <div style="background-color: #f4f4f4; border-radius: 50%; flex-grow: 0; height: 20px; width: 20px;"> </div> <div style="width: 0; height: 0; border-top: 2px solid transparent; border-left: 6px solid #f4f4f4; border-bottom: 2px solid transparent; transform: translateX(16px) translateY(-4px) rotate(30deg);"> </div> </div> <div style="margin-left: auto;"> <div style="width: 0px; border-top: 8px solid #F4F4F4; border-right: 8px solid transparent; transform: translateY(16px);"> </div> <div style="background-color: #f4f4f4; flex-grow: 0; height: 12px; width: 16px; transform: translateY(-4px);"> </div> <div style="width: 0; height: 0; border-top: 8px solid #F4F4F4; border-left: 8px solid transparent; transform: translateY(-4px) translateX(8px);"> </div> </div> </div> <div style="display: flex; flex-direction: column; flex-grow: 1; justify-content: center; margin-bottom: 24px;"> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; margin-bottom: 6px; width: 224px;"> </div> <div style="background-color: #f4f4f4; border-radius: 4px; flex-grow: 0; height: 14px; width: 144px;"> </div> </div> <p style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; line-height: 17px; margin-bottom: 0; margin-top: 8px; overflow: hidden; padding: 8px 0 7px; text-align: center; text-overflow: ellipsis; white-space: nowrap;"><a style="color: #c9c8cd; font-family: Arial,sans-serif; font-size: 14px; font-style: normal; font-weight: normal; line-height: 17px; text-decoration: none;" href="https://www.instagram.com/reel/DHne7CasELA/?utm_source=ig_embed&amp;utm_campaign=loading" target="_blank" rel="noopener">A post shared by Grounding (@groundingofficial)</a></p> </div> </blockquote> <h2>Bringing the outdoors in</h2> <p>The <a href="https://www.sciencedirect.com/science/article/pii/S2319417022001585">human body is conductive</a>, which means it can exchange electricity with Earth and artificial sources, such as electronic devices or objects.

It provides a direct connection to earth via your building’s wiring, diverting excess or unsafe voltage into the ground.

The researchers used a “double-blind” protocol, meaning neither the participants nor the researchers knew which participants were given grounding mats.</p> <p>All participants wore sleep trackers and were asked to use their mat (that is, sit or lie on it) for six hours per day. The researchers found that after 31 days, participants in the grounding mat group slept longer on average (as measured by their sleep trackers) than those in the control group.</p> <p>The researchers also used questionnaires to collect measures of insomnia, sleep quality, daytime sleepiness, and stress. After 31 days, participants in both groups improved on all measures.</p> <p>There were no differences between the grounded and ungrounded groups for sleep quality, daytime sleepiness, and stress. And while grounded participants showed significantly lower insomnia severity after the intervention, this difference was also present at the start of the study. So it’s unclear if grounding had a tangible impact on sleep.</p> <p>In another double-blind study, published in 2022, researchers in Taiwan examined the effectiveness of using grounding mats to improve sleep among patients with Alzheimer’s disease. The findings indicated that spending <a href="https://www.mdpi.com/2227-9032/10/3/581">30 minutes on a grounding mat</a> five times per week resulted in improved sleep quality.</p> <p>While previous research has suggested using grounding technologies may lead to <a href="https://pubmed.ncbi.nlm.nih.gov/25748085/">improvements in mood</a>, no differences were seen in measures of anxiety and depression in this study.</p> <h2>Grounding for gains?</h2> <p>Grounding technology has also been touted as <a href="https://www.tiktok.com/@down_to_ground/video/7310937768811597074?q=grounding%20mattress&amp;t=1742787657768">having other benefits</a>, such as reducing pain and inflammation.</p> <p>A <a href="https://doi.org/10.3389/fphys.2019.00035">2019 study</a> found participants who slept on a grounding mat after intense exercise felt less sore and showed lower levels of inflammation in their blood compared to those who were ungrounded.</p> <p>Grounding after a workout may help you feel better and recover faster, but it’s still unclear whether and how grounding affects long-term training results or fitness gains.</p> <h2>Add to cart?</h2> <p>So should you cash in on your favourite influencer’s discount code and grab a grounding mat? At the risk of spouting a common cliche of cautious scientists, our answer is that we don’t know yet.</p> <p>What we do know is the existing research, albeit emerging, has shown no evidence grounding technology can negatively affect your sleep or recovery after exercise. So if you love your grounding mat or grounding sheet, or want to see if grounding works for you, feel free to give it a go.</p> <p>Keep in mind, grounding products can retail for anywhere from around A$30 to $300 or more.</p> <p>On the other hand, grounding on the grass in the great outdoors is free. While there’s limited evidence that grounding outdoors can improve sleep, spending time in outdoor light may itself benefit <a href="https://pubmed.ncbi.nlm.nih.gov/34488088/">sleep, regulate circadian rhythms</a>, and improve mood.</p> <p>Finally, while grounding could be an interesting strategy to try, if you’re experiencing ongoing problems with your sleep, or suspect you may have a sleep disorder, the first step should be reaching out to a medical professional, such as your GP.<!-- Below is The Conversation's page counter tag.

What’s the difference between osteoarthritis and rheumatoid arthritis?

<div class="theconversation-article-body"> <p><a href="https://www.arthritis.org/health-wellness/about-arthritis/understanding-arthritis/what-is-arthritis">Arthritis</a> – an umbrella term for around <a href="https://www.arthritis.org/health-wellness/healthy-living/managing-pain/understanding-pain/sources-of-arthritis-pain">100 conditions</a> that damage the joints – affects <a href="https://pubmed.ncbi.nlm.nih.gov/39647490/">4.1 million</a> Australians. This is expected <a href="https://pubmed.ncbi.nlm.nih.gov/39647490/">to rise</a> by 31% to 5.4 million by 2040 and cost the Australian health-care system an estimated $12 billion each year.</p> <p>The two most common types, osteoarthritis and rheumatoid arthritis, can both cause joint pain, swelling and stiffness. Both are more common in <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/arthritis">women</a>. Neither can be cured.</p> <p>But their causes, risk factors and treatments are different – here’s what you need to know.</p> <h2>What is osteoarthritis?</h2> <p>Osteoarthritis is the most common form of arthritis. It affects <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/osteoarthritis">2.1 million Australians</a>, mostly older people. About a third of <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/osteoarthritis">Australians</a> aged 75 and older have the condition.</p> <p>It can affect any joint but is most common in the knees, hips, fingers, thumbs and big toes.</p> <p>The main symptom is pain, especially during movement. Other symptoms may include swelling, stiffness and changes to the shape of joints.</p> <p>The <a href="https://www.who.int/news-room/fact-sheets/detail/osteoarthritis">main risk factors</a> are ageing and obesity, as well as previous injuries or surgery. For osteoarthritis in the hands, <a href="https://pubmed.ncbi.nlm.nih.gov/35843480/">genetics</a> also play a big role.</p> <p>Signs of osteoarthritis can appear on knee scans from around <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">age 45</a> and become more common with age.</p> <p>However, this type of arthritis not simply the “wear and tear” of ageing. Osteoarthritis is a complex disease that affects the <a href="https://www.nature.com/articles/nrdp201672">whole joint</a>. This includes the <a href="https://my.clevelandclinic.org/health/body/23173-cartilage">cartilage</a> (“shock-absorbing” connective tissue protecting your bones), bones, <a href="https://my.clevelandclinic.org/health/body/21604-ligament">ligaments</a> (connective tissue holding bones and body parts in place) and joint lining.</p> <h2>How is it diagnosed?</h2> <p>Diagnosis is <a href="https://www.nice.org.uk/guidance/ng226/chapter/Recommendations#diagnosis">based on</a> symptoms (such as pain and restricted movement) and a physical exam.</p> <p>The disease generally worsens over time and cannot be reversed. But the severity of damage does not always <a href="https://pubmed.ncbi.nlm.nih.gov/21281726/">correlate with pain</a> levels.</p> <p>For this reason, x-rays and <a href="https://pubmed.ncbi.nlm.nih.gov/29886437/">MRI scans</a> are usually unhelpful. Some people with early osteoarthritis experience severe pain, but the damage won’t show up on a scan. Others with advanced and visible osteoarthritis may have few symptoms or none at all.</p> <h2>What about rheumatoid arthritis?</h2> <p>Unlike osteoarthritis, rheumatoid arthritis is an autoimmune disease. This means the immune system attacks the joint lining, causing inflammation and damage.</p> <p>Common symptoms include pain, joint swelling and stiffness, <a href="https://arthritis-research.biomedcentral.com/articles/10.1186/ar4146">especially in the morning</a>.</p> <p>Rheumatoid arthritis is less common than osteoarthritis, affecting <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/rheumatoid-arthritis">around 514,000 Australians</a>. It mostly impacts the wrists and small joints in the hands and feet, though larger joints such as the elbows, shoulders, knees and ankles can also be involved.</p> <p>It can also affect other organs, including the skin, lungs, eyes, heart and blood vessels. Fortunately, disease outside the joint has become <a href="https://pubmed.ncbi.nlm.nih.gov/38240831/">less common</a> in recent years, likely due to better and earlier treatment.</p> <p><a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/rheumatoid-arthritis?request=smoothstate">Rheumatoid arthritis</a> often develops earlier than osteoarthritis but can occur at any age. Onset is most frequent in those aged <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/musculoskeletal-conditions/contents/rheumatoid-arthritis">35–64</a>. <a href="https://pubmed.ncbi.nlm.nih.gov/21149499/">Smoking</a> increases your risk.</p> <h2>How is it diagnosed?</h2> <p>As with osteoarthritis, your doctor will diagnose rheumatoid arthritis based on your symptoms and a physical exam.</p> <p>Some other tests can be useful. Blood tests may pick up specific <a href="https://www.nature.com/articles/nrdp20181">antibodies</a> that indicate rheumatoid arthritis, although you can still have the condition <a href="https://arthritisaustralia.com.au/managing-arthritis/medical-management/blood-test-for-arthritis/">with negative results</a>.</p> <p>X-rays may also reveal joint damage if the disease is advanced. If there is uncertainty, an <a href="https://pubmed.ncbi.nlm.nih.gov/35022703/">ultrasound or MRI</a> can help detect inflammation.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=456&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/664530/original/file-20250429-56-okmp6o.jpg?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=573&amp;fit=crop&amp;dpr=3 2262w" alt="" /></a><figcaption><span class="attribution"><span class="source">The Conversation</span>, <a class="license" href="http://creativecommons.org/licenses/by-sa/4.0/">CC BY-SA</a></span></figcaption></figure> <h2>How is osteoarthritis treated?</h2> <p>No treatment can stop osteoarthritis progressing.

Q+A descends into acrimony over Welcome to Country debate

<p>The ABC’s flagship program <em>Q+A</em> erupted into heated exchanges on Monday night as panellists clashed over the role and frequency of Welcome to Country ceremonies, amid growing national debate sparked by political and community divisions.</p> <p>The discussion was triggered when audience member Peter asked how tensions over the ceremonies could be resolved "amicably" and "in the interest of all parties", following escalating disagreement between Prime Minister Anthony Albanese and Opposition Leader Peter Dutton during the current federal election campaign.</p> <p>Liberal MP Paul Fletcher argued from the Q+A panel that while it was important to recognise the “distinctive place” of Indigenous Australians, many in the community felt there were now too many ceremonial acknowledgements.</p> <p>The issue has been further inflamed after neo-Nazis booed a Welcome to Country delivered by Bunurong man Uncle Mark Brown during the Anzac Day Dawn Service at Melbourne’s Shrine of Remembrance – a move that was swiftly condemned by both major political parties.</p> <p>However, Mr Dutton later suggested that Welcome to Country ceremonies were being overused and questioned their appropriateness for solemn occasions like Anzac Day.</p> <p>On <em>Q+A</em>, Environment Minister Tanya Plibersek defended the tradition, particularly at Anzac Day events, arguing it was "perfectly appropriate" to acknowledge the service of Indigenous Australians in the military.</p> <p>Fletcher countered that veterans should be consulted on the issue, prompting a sharp exchange when Plibersek retorted that he was speaking as if Indigenous veterans did not exist. Fletcher accused her of using “straw man rhetoric”, insisting, “The role of Indigenous people in defending Australia over many conflicts has been very significant. Nobody is contesting that for a second.”</p> <p>Greens leader Adam Bandt also weighed in, launching a scathing attack on Dutton’s handling of the matter. “It’s gutter politics from an Opposition leader whose campaign is in free fall and he’s starting to punch down,” Bandt said. He accused Dutton of spreading misinformation during the Voice referendum campaign and likened his tactics to those of US President Donald Trump.</p> <p>“He’s playing from the Trump play book as his campaign is in free fall. Punching down. Playing from the Trump play book and we’ll call it out," Bandt said.</p> <p><em>Image: ABC's Q+A</em></p>

What every parent should read before becoming the bank of mum and dad

<p><span style="font-family: Calibri, sans-serif;">In late 2023, economists Jarden estimated </span><a style="color: #467886;" href="https://www.afr.com/companies/financial-services/the-bank-of-mum-and-dad-is-good-for-70-000-new-analysis-concludes-20231129-p5enpp"><span style="font-family: Calibri, sans-serif;">15 per cent of mortgage borrowers received some form of financial support</span></a><span style="font-family: Calibri, sans-serif;"> from their parents. A separate poll by comparison site Finder around the same time </span><a style="color: #467886;" href="https://au.finance.yahoo.com/news/first-home-buyers-reveal-huge-amount-aussie-parents-gifted-them-201221909.html"><span style="font-family: Calibri, sans-serif;">put the figure at 11 per cent</span></a><span style="font-family: Calibri, sans-serif;">. Fast forward to February this year, with a UBS survey </span><a style="color: #467886;" href="https://www.abc.net.au/news/2025-02-06/cost-of-living-sting-lessened-by-bank-of-mum-and-dad/104882754"><span style="font-family: Calibri, sans-serif;">suggesting almost half of first home buyers receive parental assistance</span></a><span style="font-family: Calibri, sans-serif;">. Clearly, the Bank of Mum and Dad is a rapidly growing source of funds for younger people seeking to purchase property. However, some older Australians are now paying a hefty price for having done so without adequate planning and protections.</span></p> <p><strong><span style="font-family: Calibri, sans-serif;">On the hook</span></strong></p> <p><span style="font-family: Calibri, sans-serif;">Amid the excitement of homebuying, many parents overlook the fact they could be left on the hook to cover any shortfall. The worst-case scenario here is losing your own home, as well as your child losing theirs, if you went guarantor on their loan and they defaulted and you didn’t have a backup plan. If you loaned them money which they subsequently can’t repay, the principal amount goes unrepaid and you also miss out on the interest/compound growth that money could have earned if invested elsewhere. You may even be asked to fork out more in future if your child needs help to keep the property or to subsequently buy a replacement property. Unlike for a real bank, there is no public bailout for the Bank of Mum and Dad.</span></p> <p><strong><span style="font-family: Calibri, sans-serif;">Financial shortfall</span></strong></p> <p><span style="font-family: Calibri, sans-serif;">A common problem that I and other financial advisors are now seeing is parents inadvertently giving their children more than they can actually afford. Take people who acted as Bank of Mum and Dad before the pandemic hit. They budgeted how much they would need for retirement and then gave their adult kids money towards buying a home of their own. Then COVID-19 arrived. Countless jobs were lost and businesses shuttered. Many would-be retirees were forced to stay in the workforce for longer than planned. Next came the inflation crisis, with mortgages and living costs soaring. Retirement budgets blew-out as more money was suddenly needed for everyday expenses, particularly energy, insurance and food. Meanwhile ballooning house prices over the pandemic years saw first homebuyers needing even larger deposits. That all translated to significant financial shortfalls for the Bank of Mum and Dad.</span></p> <p><strong><span style="font-family: Calibri, sans-serif;">Elder abuse</span></strong></p> <p><a style="color: #467886;" href="https://www.aihw.gov.au/family-domestic-and-sexual-violence/population-groups/older-people#abuse"><span style="font-family: Calibri, sans-serif;">Government figures from 2023</span></a><span style="font-family: Calibri, sans-serif;"> estimate one in six older Australians suffer elder abuse in some form, with 2.1 per cent experiencing financial abuse – undue control, pressure or restricted access to their own money and financial decisions. Half (53 per cent) of elder abuse perpetrators are family members, with adult children the most common offenders.</span></p> <p><span style="font-family: Calibri, sans-serif;">Given the amount of money involved in property purchases, and the stresses associated with housing affordability, the potential for the Bank of Mum and Dad to suffer elder abuse is alarmingly high.</span></p> <p><strong><span style="font-family: Calibri, sans-serif;">Relationship breakdowns</span></strong></p> <p><span style="font-family: Calibri, sans-serif;">Money is perhaps the greatest source of tension in relationships. Usually that is between partners, yet these can multiply for the Bank of Mum and Dad and its stakeholders. Some examples include:</span></p> <ul> <li><span style="font-family: Calibri, sans-serif;">You and your partner disagree on what or how much assistance to provide.</span></li> <li><span style="font-family: Calibri, sans-serif;">Your other children feel disadvantaged if they don’t receive the same financial assistance.</span></li> <li><span style="font-family: Calibri, sans-serif;">Having provided the finances, you then interfere in how your child manages the property or their general finances, causing resentment to build.</span></li> <li><span style="font-family: Calibri, sans-serif;">A marriage breakdown (yours or your child’s) affects the repayment of a loan or the nature of a mortgage guarantee.</span></li> </ul> <p><strong><span style="font-family: Calibri, sans-serif;">Protect yourself</span></strong></p> <p><span style="font-family: Calibri, sans-serif;">While supporting children is the foremost concern of the Bank of Mum and Dad, it is important to protect yourself too. A written agreement outlining the nature of the support, conditions and contingencies is crucial to keep every aligned. Independent advice from your financial adviser, lawyer, mortgage broker and accountant ensures you fully understand what you are on the hook for, how much you can afford to contribute, and whether there are less-risky options.</span></p> <p><span style="font-family: Calibri, sans-serif;">Finally, be sure that the decision to support your child’s property ambitions is your own and that you aren’t coerced into it. If you’re concerned that you may be experiencing elder abuse, call the free </span><a style="color: #467886;" href="https://www.health.gov.au/contacts/elder-abuse-phone-line"><span style="font-family: Calibri, sans-serif;">elder abuse line on 1800 353 374</span></a><span style="font-family: Calibri, sans-serif;">.</span></p> <p><strong><span style="line-height: 18.4px; font-family: Calibri, sans-serif; color: #242424;">Helen Baker is a licensed Australian financial adviser and author of the new book, <em>Money For Life: How to build financial security from firm foundations (Major Street Publishing $32.99).</em> Helen is among the 1% of financial planners who hold a master’s degree in the field.

A simple, science-backed way to sharpen thinking and improve memory – and it's not what you think

<div class="theconversation-article-body">Many of us turn to Sudoku, Wordle or brain-training apps to sharpen our minds. But research is increasingly showing one of the best ways to boost memory, focus and brain health is exercise.</p> <p>Our <a href="https://bjsm.bmj.com/content/early/2025/03/06/bjsports-2024-108589">new research</a> reviewed data from more than 250,000 participants across 2,700 studies. We found exercise helps boost brain function – whether it’s walking, cycling, yoga, dancing, or even playing active video games such as Pokémon GO.</p> <p>Moving your body improves how we think, make decisions, remember things and stay focused – no matter your age.</p> <h2>What the science says</h2> <p>Our review adds to a growing body of research that shows regular physical activity <a href="https://bjsm.bmj.com/content/early/2025/03/06/bjsports-2024-108589">improves</a> three key areas of brain function:</p> <ul> <li> <p>cognition, which is your overall ability to think clearly, learn and make decisions</p> </li> <li> <p>memory, especially short-term memory and the ability to remember personal experiences</p> </li> <li> <p>executive function, which includes focus, planning, problem-solving and managing emotions.</p> </li> </ul> <p>We conducted an umbrella review, which means we looked at the results of more than 130 high-quality research reviews that had already combined findings from many exercise studies. These studies usually involved people starting a new, structured exercise program, not just tracking the exercise they were already doing.</p> <p>To assess the effects on cognition, memory and executive function, the original studies used a range of brain function tests. These included things like remembering word lists, solving puzzles, or quickly switching between tasks – simple activities designed to reliably measure how well the brain is working.</p> <p>The improvements were small to moderate. On average, exercise led to a noticeable boost in cognition, with slightly smaller but still meaningful gains in memory and executive function.</p> <p>The benefits showed up across all age groups, though children and teens saw major gains in memory.</p> <p>People with attention-deficit hyperactivity disorder (ADHD) showed greater improvements in executive function after physical activity than other population groups.</p> <p>The brain started responding fairly quickly – many people experienced improvements after just 12 weeks of starting regular exercise.</p> <p>Generally, the greatest benefits were seen in those doing at least 30 minutes of exercise on most days of the week, aiming for a total of about 150 minutes per week.</p> <h2>What’s happening in the brain?</h2> <p>Activities such as walking or cycling can <a href="https://www.pnas.org/doi/abs/10.1073/pnas.1015950108">increase the size of the hippocampus</a>, the part of the brain responsible for memory and learning.</p> <p>In <a href="https://www.pnas.org/doi/full/10.1073/pnas.1015950108">one study</a>, older adults who did aerobic exercise for a year grew their hippocampus by 2%, effectively reversing one to two years of age-related brain shrinkage.</p> <p>More intense workouts, such as running or high-intensity interval training, can further <a href="https://onlinelibrary.wiley.com/doi/full/10.1155/2017/8305287">boost neuroplasticity</a> – the brain’s ability to adapt and rewire itself. This helps you learn more quickly, think more clearly and stay mentally sharp with age.</p> <h2>Another reason to get moving</h2> <p>The world’s population is ageing. By 2030, <a href="https://www.who.int/news-room/fact-sheets/detail/ageing-and-health">one in six of people will be aged over 60</a>. With that comes a rising risk of dementia, Alzheimer’s disease and cognitive decline.</p> <p>At the same time, many adults aren’t moving enough. One in three adults <a href="https://www.who.int/news-room/fact-sheets/detail/physical-activity">aren’t meeting the recommended levels</a> of physical activity.</p> <p>Adults <a href="https://www.who.int/initiatives/behealthy/physical-activity">should aim for</a> at least 150 of moderate exercise – such as brisk walking – each week, or at least 75 minutes of more vigorous activity, like running.</p> <p>It’s also important to incorporate muscle-strengthening exercises, such as lifting weights, into workouts at least twice a week.</p> <h2>Everyday movement counts</h2> <p>You don’t need to run marathons or lift heavy weights to benefit. Our study showed lower-intensity activities such as yoga, tai chi and “exergames” (active video games) can be just as effective – sometimes even more so.</p> <p>These activities engage both the brain and body. Tai chi, for instance, requires focus, coordination and memorising sequences.</p> <p>Exergames often include real-time decision-making and rapid response to cues. This trains attention and memory.</p> <p>Importantly, these forms of movement are inclusive. They can be done at home, outdoors, or with friends, making them a great option for people of all fitness levels or those with limited mobility.</p> <p>Although you may already be doing a lot through daily life – like walking instead of driving or carrying shopping bags home – it’s still important to find time for structured exercise, such as lifting weights at the gym or doing a regular yoga class, to get the full benefits for your brain and body.</p> <h2>Real-life applications</h2> <p>If you’re a grandparent, consider playing Wii Sports virtual tennis or bowling with your grandchild. If you’re a teenager with signs of ADHD, try a dance class, and see if it impacts your concentration in class. If you’re a busy parent, you might be more clear-headed if you can squeeze a 20-minute yoga video session between meetings.</p> <p>In each of these cases, you’re not just being active, you’re giving your brain a valuable tune-up. And unlike most brain-training apps or supplements, exercise delivers far reaching benefits, including improved <a href="https://www.sciencedirect.com/science/article/pii/S1389945721002914?casa_token=pXaOJcQJ7d0AAAAA:0i4BjaxqJ21AQ2bGXI4DfQ6twKNybrg7c2f0_Xs7t-hWyDOH0SuKGTfruy-JlC_rMokUM3iWdlSQ">sleep</a> and <a href="https://bjsm.bmj.com/content/57/18/1203">mental health</a>.</p> <p>Workplaces and schools are starting to take note. <a href="https://onlinelibrary.wiley.com/doi/10.1002/smi.2654">Short movement breaks</a> are being introduced during the workday to improve employee focus.</p> <p>Schools that incorporate <a href="https://ijbnpa.biomedcentral.com/articles/10.1186/s12966-017-0569-9">physical activity</a> into the classroom are seeing improvements in students’ attention and academic performance.</p> <p>Exercise is one of the most powerful and accessible tools we have for supporting brain health.

What would – and should – happen to the ABC under the next federal government?

<div class="theconversation-article-body">Who could possibly argue with the idea that the ABC should be efficiently run and produce excellent programs?</p> <p>No one, you would think. So why, then, has there been immediate resistance to Opposition Leader Peter Dutton’s <a href="https://www.smh.com.au/politics/federal/dutton-tells-abc-to-show-excellence-or-face-funding-razor-gang-20250402-p5lofu.html">statement</a> that, if elected next month, a Coalition government would “reward excellence” and “keep funding in place” if the ABC is “being run efficiently”?</p> <p>The fact that Coalition governments – and Dutton himself – have historically been deeply hostile to the public broadcaster is part of it. Many have picked up on the implicit threat that if his government did not find “excellence”, its funding would be cut.</p> <p>But there’s more than that. For example, who defines “excellence” and “efficiency”?</p> <p>Second, the ABC is set up by statute to be run independent of government.</p> <p>Third, the ABC has been subjected to a slew of efficiency reviews, in 1988, 1997, <a href="https://www.abc.net.au/news/2006-03-15/abc-efficient-under-funded-kpmg-report/8183700">2006</a>, <a href="https://www.infrastructure.gov.au/sites/default/files/ABC_and_SBS_efficiency_report_Redacted.pdf?acsf_files%20_redirect">2014</a> and <a href="https://www.infrastructure.gov.au/sites/default/files/2018-national-broadcasters-efficiency-review-redacted.pdf">2018</a>. Overwhelmingly, they found the ABC does more with fewer resources than its counterparts in the commercial media.</p> <p>For example, in 2006, at the behest of the Coalition government led by John Howard, KPMG found the ABC was a “broadly efficient organisation” providing a “high volume of outputs and quality relative to the level of funding it receives”.</p> <p>Let’s translate the consulting-speak. The ABC’s annual budget of $1.2 billion costs $43 per person in Australia. The cheapest subscription to Netflix costs more than twice that amount - $95.88 – and of course the ABC provides much more than a single streaming service.</p> <p>Fourth, Coalition governments’ record of antipathy towards the ABC is most obvious in how they fund it.</p> <hr /> <p><iframe id="WOgDZ" class="tc-infographic-datawrapper" style="border: 0;" src="https://datawrapper.dwcdn.net/WOgDZ/" width="100%" height="400px" frameborder="0" scrolling="no"></iframe></p> <hr /> <p>As ABC chair Kim Williams said <a href="https://www.abc.net.au/about/media-centre/speeches-and-articles/abc-chair-kim-williams-am-address-to-the-melbourne-press-club/105132866">last week</a>, in real terms the ABC’s funding is $150 million less than it was in 2013 when the coalition last came to power. This is notwithstanding the current Labor government’s restoring of at least some lost funding.</p> <p>Add to this the fear that Dutton is seeking to emulate Donald Trump. Amid the tempest of economic and social measures the US president has brought in since his inauguration in January, his attacks on public and international broadcasting have passed unnoticed by many.</p> <p>By executive order, Trump has <a href="https://mailchi.mp/poynter/president-trumps-latest-press-target-voice-of-america?e=1e851c3327">abolished Voice of America </a>(VOA), which began during the second world war. VOA has provided news to nearly 50 countries, including those that did not have press freedom. Its broadcasts are by statute meant to be accurate and objective. It has been an arm of soft power diplomacy for the US.</p> <p>Trump has also threatened to defund the public broadcasters, National Public Radio (NPR) and the Public Broadcasting Service (PBS), labelling them “radical left monsters”.</p> <p>The difference between public broadcasting in the US and Australia is that for the former, the government provides only a small percentage of its funding. Most of it comes from donations from citizens, grants from foundations and corporate sponsorship, according to <a href="https://www.forbes.com/sites/antoniopequenoiv/2025/03/27/will-trump-defund-npr-and-pbs-heres-what-we-know-as-president-attacks-the-broadcasters/">a recent report</a> in Forbes.</p> <p>PBS and NPR occupy a smaller part of the overall US media landscape than the ABC and SBS in Australia, but NPR’s reporters in particular have been actively, if dispassionately, reporting on the Trump Mark II administration’s tumultuous first few months.</p> <p>Like the VOA, the ABC’s international broadcasting arm is largely invisible to audiences in its host country. This means any cuts could well pass unnoticed, unlike, say, if the ABC said it could no longer afford to air the children’s TV series, Bluey.</p> <p>Through radio, TV, and now online, the ABC has broadcast to Australia’s neighbours since the second world war, initially as an agent to spread democratic value, but in more recent decades to model effective public interest journalism. The ABC, like the BBC, has a charter of independence.</p> <p>The ABC’s work in the international arena, through Radio Australia and ABC Australia, is vital, not only to bolster national security by providing trusted news and information about Australia and its allies, but by working alongside and supporting local Indo-Pacific news organisations.</p> <p>The Albanese Labor government appears to have understood this threat, providing some extra funding for the international services mostly in response to China’s increased presence in the region, as Alexandra Wake argued in her <a href="https://link.springer.com/book/10.1007/978-3-031-47571-9">2024 book</a> Transnational Broadcasting in the Indo-Pacific.</p> <p>Labor’s funding boost remains inadequate, though, to properly broadcast an Australian voice to the region because, she argued, of increasingly fraught relations between nations, and a complex political and media environment.</p> <p>One of the most pressing priorities now is to extend the Labor government’s Pacific Security and Engagement Initiatives (the original $8 million per year) which is due to end in June 2026. Without this, the ABC will have transmission to the region, but next to no appropriate content.</p> <p>Australia needed to rectify past mistakes by increasing international broadcast funding and protecting that funding from future government cuts. Australia also needed to adopt the long-term thinking that China displayed if it was to counteract China’s strategic ambitions for the region.</p> <p>By closing VOA, Trump and his government efficiency wrecking ball, Elon Musk, have actually left open an opportunity for Australia to lean into the unique strategic advantage granted by Australia’s economic and geographical place in the region.</p> <p>The move to cut US aid supporting journalism extends to smaller outfits such as Benar News Pacific, which recently <a href="https://www.benarnews.org/english/news/philippine/letter-from-editors-benarnews-pauses-operations-04022025104657.html">told its audience</a> it was “pausing operations”.</p> <p>For the past decade, Benar News (and its parent Radio Free Asia) has been reporting across the region on security, politics and human rights. “The US administration has withheld the funding that we rely on to bring our readers and viewers the news from Indonesia, Malaysia, Thailand, Bangladesh, the Philippines and island-states and territories in the Pacific,” it said in a letter from the editors.</p> <p>Such local news services may be small but are a vital bulwark in the multi-polar world Trump seeks to shape.<!-- Below is The Conversation's page counter tag.

Our ancestors didn’t eat 3 meals a day. So why do we?

<div class="theconversation-article-body"> <p>Pop quiz: name the world’s most famous trio? If you’re a foodie, then your answer might have been breakfast, lunch and dinner. It’s an almost universally accepted trinity – particularly in the Western world.</p> <p>But how did it come about?</p> <h2>The first meals</h2> <p><a href="https://theconversation.com/when-did-we-become-fully-human-what-fossils-and-dna-tell-us-about-the-evolution-of-modern-intelligence-143717#:%7E:text=Fossils%20and%20DNA%20suggest%20people,%3A%2050%2C000%2D65%2C000%20years%20ago">Early humans</a> were nomadic. Forming small communities, they would travel with the seasons, following local food sources.</p> <p>While we can only guess what daily mealtimes rhythms looked like, evidence dating back <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">30,000 years</a> from the South Moravia region, Czech Republic, shows people visited specific settlements time and again. They gathered around hearths, cooking and sharing food: the first signs of human “commensality”, the practice of eating together.</p> <p>One of the best-preserved hunter-gatherer sites we’ve found is <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">Ohalo II</a> – located on the shores of the modern-day Sea of Galilee (also called Lake Tiberias or Lake Kinneret) in Israel, and dating back some 23,000 years.</p> <p>In addition to several small dwellings with hearths, it provides evidence of diverse food sources, including more than 140 types of seeds and nuts, and various birds, fish and mammals.</p> <p>The development of <a href="https://education.nationalgeographic.org/resource/development-agriculture/">agricultural knowledge</a> some 12,000 years ago gave rise to permanent settlements. The earliest were in the Levant region (across modern-day Iraq, southwestern Iran and eastern Turkey), in an area called the “Fertile Crescent”.</p> <p>Permanent agriculture led to the production of a <a href="https://www.nationalgeographic.com/foodfeatures/evolution-of-diet/">surplus of food</a>. The ability to stay in one place with food on-hand meant the time it took to cook no longer mattered as much.</p> <p>It quickly became common to eat one <a href="https://www.bloomsbury.com/us/history-of-the-world-in-6-glasses-9780802718594/">light meal</a> early in the day, followed by a larger <a href="https://global.oup.com/academic/product/feast-9780199209019?cc=nz&lang=en&">hearth-prepared meal</a> later on. The specific timings would have varied between groups.</p> <h2>Eating together as a rule</h2> <p>The communal nature of foraging and hunting, and later farming, meant humans almost always ate their meals in the <a href="https://doi.org/10.1525/gfc.2009.9.3.42">company of others</a>. In the ancient city-state of Sparta, in the <a href="https://doi.org/10.2307/293895">4th century BCE</a>, these practices were codified as common main meals called <a href="https://doi.org/10.1525/gfc.2017.17.2.51"><em>syssitia</em></a> (meaning “eating together”).</p> <p>These meals were consumed at the end of the day in communal dining halls. Food was served by young boys to tables of 15 or so men who lived together and fought in the same <a href="https://www.perseus.tufts.edu/hopper/text?doc=Perseus%3Atext%3A1999.04.0063%3Aalphabetic+letter%3DS%3Aentry+group%3D5%3Aentry%3Dsyssitia-cn">military division</a>. The men gradually shared generational knowledge with the young boys, who themselves would join the tables by age 20.</p> <p>In the 5th century BCE, Greek historian Herodotus <a href="https://www.penguin.co.nz/books/the-histories-9780140455397">wrote about</a> how <em>syssitia</em> evolved from a Spartan military practice to having deep political meaning in society. Similarly, <a href="https://www.penguin.co.nz/books/the-republic-9780140455113">Plato</a> <a href="https://www.penguin.co.nz/books/the-laws-9780140449846">wrote</a> common meals were an integral component of civil society, and that missing a meal without good reason was a civic offence.</p> <p>By dining in <a href="https://doi.org/10.2307/293895">full view</a> of the rest of society, citizens were compelled to maintain self-discipline. Mealtime was also an opportunity for social linkage, and <a href="https://doi.org/10.1525/gfc.2017.17.2.51">important discussions</a> ranging from business deals to politics.</p> <p>The eating habits of Spartan women are missing in the texts, although it is implied they <a href="https://doi.org/10.1525/gfc.2017.17.2.51">ate at home</a>.</p> <h2>Bunches of lunches</h2> <p>Counter to the tough Spartan way of life, the Romans enjoyed their main meal, <a href="https://www.press.jhu.edu/books/title/1550/everyday-life-ancient-rome?srsltid=AfmBOooVPsJL24HR9woTdVNQwEG1uCU7q0k7r2beD-KD13m0KX-l1dSY"><em>cena</em></a>, earlier in the day, followed by a lighter meal just before bed.</p> <p>The northern European tribes tended towards two larger meals per day, as more <a href="https://doi.org/10.1002/ajpa.23071">sustenance</a> is required in colder climes. To the Vikings, these meals were known as <a href="https://www.historyonthenet.com/what-did-vikings-eat"><em>dagmal</em> and <em>nattmal</em></a>, or day meal and night meal. <em>Nattmal</em> was the cooked evening meal, while <em>dagmal</em> usually consisted of leftover <em>nattmal</em> with the addition of bread and beer or mead.</p> <p>In Australia, evidence suggests Aboriginal peoples tended toward a <a href="https://www.tandfonline.com/doi/full/10.1080/03122417.2022.2089395">daily single meal</a>, which aligns with the predominant method of cookery: slow-cooking with hot coals or rocks in an <a href="https://doi.org/10.1080/03122417.2022.2089395">earth oven</a>. This underground oven, used by Aboriginal and also Torres Strait Islander communities, was referred to as a <a href="https://www.facebook.com/watch/?v=745326709638881&t=0"><em>kup murri</em></a> or <a href="https://www.sbs.com.au/food/the-cook-up-with-adam-liaw/recipe/slow-cooker-kap-mauri/lfza7eqs4"><em>kap mauri</em></a> by some groups.</p> <p>This is similar to other Indigenous preparations throughout the Pacific, such as the New Zealand Māori <a href="https://doi.org/10.1080/15528014.2024.2381305"><em>hāngī</em></a>, Hawaiian <a href="https://www.jstor.org/stable/20707103?seq=1"><em>imu</em></a>, Fijian <a href="https://www.proquest.com/docview/1021389307?accountid=8440&parentSessionId=605Pt1iTclBEC77VSlZvrnxxY%2Bdc7e%2Bx9pT4MgRLPqQ%3D&sourcetype=Dissertations%20&%20Theses"><em>lovo</em></a>, and even the Mayan <a href="https://doi.org/10.1007/s12231-012-9207-2"><em>píib</em></a>.</p> <p>The once-daily meal would have been supplemented with snacks throughout the day.</p> <h2>Three’s the magic number</h2> <p>The timing of meals was heavily influenced by class structure, local climate and people’s <a href="https://www.wiley.com/en-us/Cuisine+and+Culture%3A+A+History+of+Food+and+People%2C+3rd+Edition-p-9780470403716">daily activities</a>. Practicality also played a part. Without reliable lighting, meals had to be prepared and eaten before dark. In settled parts of Northern Europe, this could be as early as 3pm.</p> <p>So how did we go from one or two main meals, to three? The answer may lie with the British Royal Navy.</p> <p>Since its inception in the 16th century, the navy served <a href="https://www.historyhit.com/what-did-sailors-in-the-georgian-royal-navy-eat/">three regular meals</a> to align with the shipboard routine. This included a simple breakfast of ship’s biscuits, lunch as the main meal, and dinner as more of a light supper.</p> <p>Some sources suggest the term “<a href="https://www.grammar-monster.com/sayings_proverbs/square_meal.htm">square meal</a>” may have come from the square wooden trays meals were served in.</p> <figure class="align-center zoomable"><a href="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=1000&fit=clip"><img src="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=600&h=455&fit=crop&dpr=1 600w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=600&h=455&fit=crop&dpr=2 1200w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=600&h=455&fit=crop&dpr=3 1800w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=45&auto=format&w=754&h=572&fit=crop&dpr=1 754w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=30&auto=format&w=754&h=572&fit=crop&dpr=2 1508w, https://images.theconversation.com/files/660040/original/file-20250407-56-xgt2pm.jpg?ixlib=rb-4.1.0&q=15&auto=format&w=754&h=572&fit=crop&dpr=3 2262w" alt="" /></a><figcaption><span class="caption">Initially, sailors recieved a daily gallon of beer with meals.

A new COVID variant is on the rise: what you need to know

<div class="theconversation-article-body"> <p>More than five years since COVID was <a href="https://www.who.int/europe/emergencies/situations/covid-19">declared a pandemic</a>, we’re still facing the regular emergence of new variants of the virus, SARS-CoV-2.</p> <p>The latest variant on the rise is LP.8.1. It’s <a href="https://www.health.gov.au/resources/collections/australian-respiratory-surveillance-reports-2025">increasing in Australia</a>, making up close to <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20250322.pdf">one in five COVID cases</a> in New South Wales.</p> <p>Elsewhere it’s become even more dominant, comprising at least three in five cases <a href="https://inews.co.uk/news/health/lp-covid-variant-cases-future-waves-3598768">in the United Kingdom</a>, for example.</p> <p>So what is LP.8.1? And is it cause for concern? Let’s look at what we know so far.</p> <h2>An offshoot of Omicron</h2> <p>LP.8.1 was first <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">detected in July 2024</a>. It’s a descendant of Omicron, specifically of KP.1.1.3, which is descended from <a href="https://theconversation.com/the-emergence-of-jn-1-is-an-evolutionary-step-change-in-the-covid-pandemic-why-is-this-significant-220285">JN.1</a>, a subvariant that caused large waves of COVID infections around the world in late 2023 and early 2024.</p> <p>The <a href="https://www.who.int/activities/tracking-SARS-CoV-2-variants">World Health Organization</a> (WHO) designated LP.8.1 as a <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">variant under monitoring</a> in January. This was in response to its significant growth globally, and reflects that it has genetic changes which may allow the virus to spread more easily and pose a greater risk to human health.</p> <p>Specifically, LP.8.1 has mutations at six locations in its spike protein, the protein which allows SARS-CoV-2 to attach to our cells. One of these mutations, V445R, is thought to allow this variant to spread more easily relative to other circulating variants. V445R has been shown to increase binding to human lung cells in <a href="https://www.thelancet.com/journals/laninf/article/PIIS1473-3099(25)00015-5/fulltext">laboratory studies</a>.</p> <figure class="align-center "><img src="https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" sizes="(min-width: 1466px) 754px, (max-width: 599px) 100vw, (min-width: 600px) 600px, 237px" srcset="https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=600&amp;h=468&amp;fit=crop&amp;dpr=1 600w, https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=600&amp;h=468&amp;fit=crop&amp;dpr=2 1200w, https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=600&amp;h=468&amp;fit=crop&amp;dpr=3 1800w, https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;h=588&amp;fit=crop&amp;dpr=1 754w, https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=30&amp;auto=format&amp;w=754&amp;h=588&amp;fit=crop&amp;dpr=2 1508w, https://images.theconversation.com/files/658901/original/file-20250401-56-eywcgb.png?ixlib=rb-4.1.0&amp;q=15&amp;auto=format&amp;w=754&amp;h=588&amp;fit=crop&amp;dpr=3 2262w" alt="A chart showing the distribution of different COVID variants in different colours." /><figcaption><span class="caption">The proportion of COVID cases caused by LP.8.1 has been rising in New South Wales.</span> <span class="attribution"><a class="source" href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20250322.pdf">NSW Health</a></span></figcaption></figure> <p>Notably, the symptoms of LP.8.1 don’t appear <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">to be any more severe</a> than other circulating strains.

What’s more, LP.8.1 remains a variant under monitoring, rather than a variant of interest or a variant of concern.</p> <p>In other words, these changes to the virus with LP.8.1 are small, and not likely to make a big difference to the trajectory of the pandemic.</p> <h2>That doesn’t mean cases won’t rise</h2> <p>COVID as a whole is still a major national and international health concern. So far this year there have been close to <a href="https://www.health.gov.au/resources/collections/australian-respiratory-surveillance-reports-2025">45,000 new cases recorded in Australia</a>, while around <a href="https://covidlive.com.au/report/daily-hospitalised/aus">260 people are currently in hospital</a> with the virus.</p> <p>Because many people are no longer testing or reporting their infections, the real number of cases is probably far higher.</p> <p>In <a href="https://www.health.gov.au/resources/collections/australian-respiratory-surveillance-reports-2025">Australia</a>, LP.8.1 has become the <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20250322.pdf">third most dominant strain in NSW</a> (behind <a href="https://theconversation.com/xec-is-now-in-australia-heres-what-we-know-about-this-hybrid-covid-variant-239292">XEC</a> and KP.3).</p> <p>It <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Documents/respiratory-surveillance-20250322.pdf">has been growing</a> over the past couple of months and this trend looks set to continue.</p> <p>This is not to say it’s not growing similarly in other states and territories, however NSW Health publishes <a href="https://www.health.nsw.gov.au/Infectious/covid-19/Pages/reports.aspx">weekly respiratory surveillance</a> with a breakdown of different COVID variants in the state.</p> <p>Sequences of LP.8.1 in the <a href="https://gisaid.org/">GISAID database</a>, used to track the prevalence of variants around the world, increased from <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">around 3%</a> at the end of 2024 to 38% of global sequences as of <a href="https://x.com/Mike_Honey_/status/1905816340331728914">mid March</a>.</p> <p>In some countries it’s climbed particularly high. In the United States LP.8.1 is responsible for <a href="https://covid.cdc.gov/covid-data-tracker/#variant-proportions">55% of cases</a>. In <a href="https://inews.co.uk/news/health/lp-covid-variant-cases-future-waves-3598768">the UK</a>, where LP.8.1 is making up at least 60% of cases, scientists fear <a href="https://inews.co.uk/news/science/new-covid-wave-cases-hospitalisations-3611459?srsltid=AfmBOor_V7pQrPMPhUYQA2KCZgRfsI_CpxTwIRiHDFJHIJhq2kbAmD42">it may be driving a new wave</a>.</p> <h2>Will COVID vaccines work against LP.8.1?</h2> <p>Current COVID vaccines, including the most recently available <a href="https://theconversation.com/new-covid-vaccines-may-be-coming-to-australia-heres-what-to-know-about-the-jn-1-shots-237652">JN.1 shots</a>, are still expected to <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">offer good protection</a> against symptomatic and severe disease with LP.8.1.</p> <p>Nonetheless, due to its designation as a variant under monitoring, WHO member countries will continue to study the behaviour <a href="https://www.who.int/publications/m/item/risk-evaluation-for-sars-cov-2-variant-under-monitoring-lp81">of the LP.8.1 variant</a>, including any potential capacity to evade our immunity.</p> <p>While there’s no cause for panic due to LP.8.1 variant at this stage, COVID can still be a severe disease for some. Continued vigilance and vaccination, particularly <a href="https://www.health.gov.au/our-work/covid-19-vaccines/getting-your-vaccination">for medically vulnerable groups</a>, is essential in minimising the impact of the disease.<!-- Below is The Conversation's page counter tag.

Refinancing your home later in life – what you need to know

<p>There are many reasons why you may look to refinance your home. The obvious one is to lower mortgage repayments with a better rate. However, other reasons people refinance later in life include:</p> <ul> <li>unlocking equity to invest</li> <li>paying down other debts</li> <li>buying a holiday home</li> <li>funding extended travel</li> <li>launching a new business</li> <li>supporting children with a property deposit</li> </ul> <p>Regardless of why you want to refinance, the points below will help you navigate your options.</p> <p><strong>Changing lenders</strong></p> <p>It may have been a while since you last revisited your mortgage, meaning you may not be aware of current lending options and traps.</p> <p>A common trick lenders use is the so-called “headline rate” to grab your attention. However, this interest rate is typically not what you end up paying. It may only be an introductory rate for the first few months, or hefty fees attached may wipe out any savings.</p> <p>Banks aren’t the only ones offering loans nowadays. Registered non-bank lenders, fintechs and online lenders can refinance your mortgage and provide other credit services the same as any bank; they just don’t take cash deposits. Alternatively, you could explore credit unions and mutual societies.</p> <p>Also consider any shareholder benefits you may have. Most banks have done away with them now but may still honour pre-existing ones. If you change lenders, you could lose this entitlement – permanently.</p> <p><strong>Reverse mortgages</strong></p> <p>Generally, only available to people aged 60-plus, a reverse mortgage effectively allows you to unlock equity in your home without you needing to make immediate repayments.</p> <p>However, they often have strict conditions including:</p> <ul> <li>minimum borrowing amounts</li> <li>maximum borrowing ratios</li> <li>higher interest rates than standard mortgages</li> </ul> <p>Crucially, the interest accrues over time and is repaid when you sell, move or pass away. As such, your debt liability grows over time – potentially impacting your future living arrangements and how much is left for beneficiaries in your will.  The Govt has the “loan equity scheme” as another option to lenders.  I just want to highlight the need to be careful with reverse mortgages.</p> <p><strong>Changing homes</strong></p> <p>Rather than selling, downsizing could involve making an investment property your primary residence and then renting out your existing home.</p> <p>This approach may require you to refinance both loans simultaneously. There will also be tax considerations to work through – including Capital Gains Tax liabilities when you do sell, negative gearing, depreciation, and changes to your income tax.</p> <p>Then there are the lifestyle factors to weigh up, especially if you are moving to a different area:</p> <ul> <li>living expenses</li> <li>insurance and travel costs</li> <li>access to healthcare</li> <li>rental income</li> <li>property management expenses</li> </ul> <p>Remember that if you have a Self Managed Super Fund (SMSF), it CANNOT own any property that you directly use yourself, including your home.</p> <p><strong>Becoming Bank of Mum and Dad</strong></p> <p>Refinancing can unlock equity to support adult children with their first property deposit. However, it isn’t without its risks.</p> <p>Ask yourself honestly:</p> <ul> <li>Will this be a gift or loan?</li> <li>If a loan, under what terms? Will interest be applied? How and when will repayments be made? What if they default?</li> <li>What happens if their relationship breaks down, will you get your money back?</li> <li>How does going without that money affect your retirement?</li> <li>Do you have alternative assets to support you if your circumstances change?</li> <li>How does this affect inheritances or deposit contributions to your other children?</li> <li>Can you assist them another way without using your home equity?</li> </ul> <p>Draw up a written agreement outlining all conditions and scenarios to avoid disagreements in the future.</p> <p><strong>Pension impacts</strong></p> <p>Don’t overlook how refinancing your home could impact your pension. While your home is exempt from the means test, any income or assets you generate from unlocking equity is not.</p> <p>You could inadvertently see your pension amount reduced or your eligibility voided altogether. This would come as a nasty shock if you haven’t pre-budgeted for such a change!</p> <p><strong>Getting advice</strong></p> <p>To ensure you get the best bang for your buck when refinancing, be sure to enlist the help of a good:</p> <ul> <li>mortgage broker to source the best loans for your circumstances</li> <li>insurance broker to ensure your cover is right sized for your needs, risk and budget</li> <li>accountant to work through any tax implications</li> <li>estate planner to manage any changes</li> <li>financial adviser to keep your investments and financial strategy working for you</li> </ul> <p>Ultimately, decisions – including about refinancing – are only as good the information you have at hand. So, make sure you have all the relevant facts before signing on the dotted line.</p> <p><em><span style="line-height: 18.4px; font-family: Calibri, sans-serif; color: #242424;">Helen Baker is a licensed Australian financial adviser and author of the new book, Money For Life: How to build financial security from firm foundations (Major Street Publishing $32.99). Helen is among the 1% of financial planners who hold a master’s degree in the field.

Do stem cell injections for knee osteoarthritis actually work?

<div class="theconversation-article-body">More than 500 million people around the world <a href="https://www.thelancet.com/journals/lanrhe/article/PIIS2665-9913(23)00163-7/fulltext">live with osteoarthritis</a>. The knee is affected more often than any other joint, with symptoms (such as pain, stiffness and reduced movement) affecting work, sleep, sport and <a href="https://www.aihw.gov.au/reports/chronic-musculoskeletal-conditions/osteoarthritis">daily activities</a>.</p> <p>Knee osteoarthritis is often thought of as thinning of the protective layer of cartilage within the joint. But we now understand it affects all the structures of the joint, including the bones, muscles and nerve endings.</p> <p>While there are things that <a href="https://www.safetyandquality.gov.au/standards/clinical-care-standards/osteoarthritis-knee-clinical-care-standard/information-consumers-osteoarthritis-knee-clinical-care-standard">can be done to manage</a> the symptoms of knee osteoarthritis, there is no cure, and many people experience persistent pain. As a result, an opportunity exists for <a href="https://www.rheuma.com.au/stem-cell-therapy-good-bad-ugly/174">as yet unproven treatments</a> to enter the market, often before regulatory safeguards can be put in place.</p> <p>Stem cell injections are one such treatment. A <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013342.pub2">new review</a> my colleagues and I published this week finds that evidence of their benefits and harms remains elusive.</p> <h2>Stem cell treatments</h2> <p>Stem cells are already established as treatments for some diseases – <a href="https://www.lymphoma.org.au/lymphoma/treatments/stem-cell-transplants/autologous-stem-cell-transplant/">mostly disorders of the blood</a>, bone marrow or immune system – which has led to suggestions they could be used for a much wider array of conditions.</p> <p>Stem cells have been touted as promising treatments for osteoarthritis because they have special properties which allow them to replicate and develop into the mature healthy cells that make up our body’s organs and other tissues, including cartilage.</p> <p>Stem cell treatments for osteoarthritis generally involve <a href="https://www.aboutstemcells.org/treatments">taking a sample of tissue</a> from a site that is rich in stem cells (such as bone marrow or fat), treating it to increase the number of stem cells, then injecting it into the joint.</p> <p>The hope is that if the right type of stem cells can be introduced into an osteoarthritic joint in the right way and at the right time, they may help to repair damaged structures in the joint, or have other effects such as reducing inflammation.</p> <p>But no matter how convincing the theory, we need good evidence for effectiveness and safety before a new therapy is adopted into practice.</p> <p>Stem cell injections have not been approved by Australia’s <a href="https://www.tga.gov.au/news/news/stem-cell-treatments-and-regulation-quick-guide-consumers#:%7E:text=Does%20the%20TGA%20regulate%20stem,does%20not%20regulate%20medical%20practice">Therapeutic Goods Administration</a> for the treatment of osteoarthritis. Nonetheless, some clinics in Australia and around the world still offer them.</p> <p>Because of the regulatory restrictions, we don’t have reliable numbers on how many procedures are being done.</p> <p>They’re not covered by Medicare, so the procedure can cost the consumer thousands of dollars.</p> <p>And, as with any invasive procedure, both the <a href="https://coroners.nsw.gov.au/documents/findings/2016/Findings%20Drysdale.pdf">harvest of stem cells</a> and the joint injection procedure may carry the potential for harm, such as infection.</p> <h2>What we found</h2> <p>Our <a href="https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD013342.pub2">new review</a>, published by the independent, international group the Cochrane Collaboration, looks at all 25 randomised trials of stem cell injections for knee osteoarthritis that have been conducted worldwide to date. Collectively, these studies involved 1,341 participants.</p> <p>We found stem cell injections may slightly improve pain and function compared with a placebo injection, but the size of the improvement may be too small for the patient to notice.</p> <p>The evidence isn’t strong enough to determine whether there is any improvement in quality of life following a stem cell injection, whether cartilage regrows, or to estimate the risk of harm.</p> <p>This means we can’t confidently say yet whether any improvement that might follow a stem cell injection is worth the risk (or the cost).</p> <h2>Hope or hype?</h2> <p>It’s not surprising we invest hope in finding a transformative treatment for such a common and disabling condition. Belief in the benefits of stem cells is widespread – more than <a href="https://www.arthroscopyjournal.org/article/S0749-8063(21)00571-5/abstract">three-quarters of Americans</a> believe stem cells can relieve arthritis pain and more than half believe this treatment to be curative.</p> <p>But what happens if a new treatment is introduced to practice before it has been clearly proven to be safe and effective?</p> <p>The use of an unproven, invasive therapy is not just associated with the risks of the intervention itself. Even if the treatment were harmless, there is the risk of unnecessary cost, inconvenience, and a missed opportunity for the patient to use existing therapies that are known to be effective.</p> <p>What’s more, if we need to play catch-up to try to establish an evidence base for a treatment that’s already in practice, we risk diverting scarce research resources towards a therapy that may not prove to be effective, simply because the genie is out of the bottle.</p> <h2>Working towards a clearer answer</h2> <p>Several more large <a href="https://anzctr.org.au/Trial/Registration/TrialReview.aspx?ACTRN=12620000870954">clinical trials</a> are currently underway, and should increase our understanding of whether stem cell injections are safe and effective for knee osteoarthritis.</p> <p>Our review incorporates “<a href="https://www.cochrane.org/news/cochranes-pioneering-role-living-evidence">living evidence</a>”. This means we will continue to add the results of new trials as soon as they’re published, so the review is always up to date, and offers a comprehensive and trustworthy summary to help people with osteoarthritis and their health-care providers to make informed decisions.</p> <p>In the meantime, there are a number of <a href="https://www.racgp.org.au/clinical-resources/clinical-guidelines/key-racgp-guidelines/view-all-racgp-guidelines/knee-and-hip-osteoarthritis/summary-plain-language">evidence-based treatment options</a>. Non-drug treatments such as physiotherapy, regular exercise, maintaining a healthy weight, and cognitive behavioural therapy can be more effective than you think. Anti-inflammatory and pain medications can also play a supporting role.</p> <p>Importantly, it’s not inevitable that osteoarthritic joints get worse with time. So, even though <a href="https://aoanjrr.sahmri.com/background">joint replacement surgery</a> is often highly effective, it’s the last resort and fortunately, many people never need to take this step.<!-- Below is The Conversation's page counter tag.
