At 10almonds we talk often of the health benefits of walking, so what’s new here?
As the subtitle suggests: a new scientific exploration!
Dr. Shane O’Mara is a professor of experimental brain research—and a keen walker. Combining his profession and his passion, he offers us a uniquely well-grounded perspective.
While the writing style is very readable, there’s a lot of science referenced here, with many studies cited. We love that!
We begin our journey by learning what we have in common with sea squirts, and what we have different from all other apes. What we can learn from other humans, from toddlers to supercentenarians.
As one might expect from a professor of experimental brain research, we learn a lot more about what walking does for our brain, than for the rest of our body. We’ve previously talked about walking and cardiovascular health, and brown adipose tissue, and benefits to the immune system, but this book remains steadfastly focused on the brain.
Which just goes to show, what a lot there is to say for the science-based benefits to our brain health, both neurologically and psychologically!
One of the things at which Dr. O’Mara excels that this reviewer hasn’t seen someone do so well before, is neatly tie together the appropriate “why” and “how” to each “what” of the brain-benefits of walking. Not just that walking boosts mood or creativity or problem-solving, say, but why and how it does so.
Often, understanding that can be the difference between being motivated to actually do it or not!
Bottom line: if there’s a book that’ll get you lacing up your walking shoes, this’ll be the one.

Thriving Beyond Fifty – by Will Harlow
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We’ve featured this author sometimes in our video section; he’s an over-50s specialist physiotherapist with a lot of very functional advice to offer.
In this book, Harlow focusses heavily on three things: mobility, strength, endurance.
You may not want to be a gymnast, powerlifter, or marathon-runner, but these things are important for us all to maintain to at least a fair degree:
- Mobility can be the difference between tweaking one’s shoulder getting something from a high shelf, or not
- Strength can be the difference between being able to get back up, or not
- Endurance can be the difference between coming back from a long day on your feet and thinking “that was a good day; I’m looking forward to tomorrow now”, or not
One of the greatest strengths of this book is its comprehensive troubleshooting aspect; if you have a weak spot, chances are this book has the remedy.
As for the style, it’s quite casual/conversational in tone, but without skimping on science and detail. It’s clear, explanatory, and helpful throughout.
Bottom line: if you’d like to maintain/improve mobility, strength, and endurance, then this book is a very recommendable resource.

Tell Yourself a Better Lie – by Marissa Peer
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
As humans, we generally lie to ourselves constantly. Or perhaps we really believe some of the things we tell ourselves, even if they’re not objectively necessarily true:
- I’ll always be poor
- I’m destined to be alone
- I don’t deserve good things
- Etc.
Superficially, it’s easy to flip those, and choose to tell oneself the opposite. But it feels hollow and fake, doesn’t it? That’s where Marissa Peer comes in.
Our stories that we tell ourselves don’t start where we are—they’re generally informed by things we learned along the way. Sometimes good lessons, sometimes bad ones. Sometimes things that were absolutely wrong and/or counterproductive.
Peer invites the reader to ask “What if…”, unravel how the unhelpful lessons got wired into our brains in the first place, and then set about untangling them.
“Tell yourself a better lie” does not mean self-deceit. It means that we’re the authors of our own stories, so we might as well make them work for us. Many things in life are genuinely fixed; others are open to interpretation.
Sorting one from the other, and then treating them correctly in a way that’s helpful to us? That’s how we can stop hurting ourselves, and instead bring our own stories around to uplift and fortify us.

An unbroken night’s sleep is a myth. Here’s what good sleep looks like
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
What do you imagine a good night’s sleep to be?
Often when people come into our sleep clinic seeking treatment, they share ideas about healthy sleep.
Many think when their head hits the pillow, they should fall into a deep and restorative sleep, and emerge after about eight hours feeling refreshed. They’re in good company – many Australians hold the same belief.
In reality, healthy sleep is cyclic across the night, as you move in and out of the different stages of sleep, often waking up several times. Some people remember one or more of these awakenings, others do not. Let’s consider what a healthy night’s sleep looks like.
Bricolage/Shutterstock Sleep cycles are a roller-coaster
As an adult, our sleep moves through different cycles and brief awakenings during the night. Sleep cycles last roughly 90 minutes each.
We typically start the night with lighter sleep, before moving into deeper sleep stages, and rising again into rapid eye movement (REM) sleep – the stage of sleep often linked to vivid dreaming.
If sleeping well, we get most of our deep sleep in the first half of the night, with REM sleep more common in the second half of the night.
Deepest sleep usually happens during the first half of the night. Verin/Shutterstock Adults usually move through five or six sleep cycles in a night, and it is entirely normal to wake up briefly at the end of each one. That means we might be waking up five times during the night. This can increase with older age and still be healthy. If you’re not remembering these awakenings that’s OK – they can be quite brief.
What does getting a ‘good’ sleep actually mean?
You’ll often hear that adults need between seven and nine hours of sleep per night. But good sleep is about more than the number of hours – it’s also about the quality.
For most people, sleeping well means being able to fall asleep soon after getting into bed (within around 30 minutes), sleeping without waking up for long periods, and waking feeling rested and ready for the day.
You shouldn’t be feeling excessively sleepy during the day, especially if you’re regularly getting at least seven hours of refreshing sleep a night (this is a rough rule of thumb).
But are you noticing you’re feeling physically tired, needing to nap regularly and still not feeling refreshed? It may be worthwhile touching base with your general practitioner, as there a range of possible reasons.
Common issues
Sleep disorders are common. Up to 25% of adults have insomnia, a sleep disorder where it may be hard to fall or stay asleep, or you may wake earlier in the morning than you’d like.
Rates of common sleep disorders such as insomnia and sleep apnoea – where your breathing can partially or completely stop many times during the night – also increase with age, affecting 20% of early adults and 40% of people in middle age. There are effective treatments, so asking for help is important.
Beyond sleep disorders, our sleep can also be disrupted by chronic health conditions – such as pain – and by certain medications.
There can also be other reasons we’re not sleeping well. Some of us are woken by children, pets or traffic noise during the night. These “forced awakenings” mean we may find it harder to get up in the morning, take longer to leave bed and feel less satisfied with our sleep. For some people, night awakenings may have no clear cause.
A good way to tell if these awakenings are a problem for you is by thinking about how they affect you. When they cause feelings of frustration or worry, or are impacting how we feel and function during the day, it might be a sign to seek some help.
If waking up in the night is interfering with your normal day-to-day activities, it may indicate a problem. BearFotos/Shutterstock We also may struggle to get up in the morning. This could be for a range of reasons, including not sleeping long enough, going to bed or waking up at irregular times – or even your own internal clock, which can influence the time your body prefers to sleep.
If you’re regularly struggling to get up for work or family needs, it can be an indication you may need to seek help. Some of these factors can be explored with a sleep psychologist if they are causing concern.
Can my smart watch help?
It is important to remember sleep-tracking devices can vary in accuracy for looking at the different sleep stages. While they can give a rough estimate, they are not a perfect measure.
In-laboratory polysomnography, or PSG, is the best standard measure to examine your sleep stages. A PSG examines breathing, oxygen saturation, brain waves and heart rate during sleep.
Rather than closely examining nightly data (including sleep stages) from a sleep tracker, it may be more helpful to look at the patterns of your sleep (bed and wake times) over time.
Understanding your sleep patterns may help identify and adjust behaviours that negatively impact your sleep, such as your bedtime routine and sleeping environment.
And if you find viewing your sleep data is making you feel worried about your sleep, this may not be useful for you. Most importantly, if you are concerned it is important to discuss it with your GP who can refer you to the appropriate specialist sleep health provider.

What will aged care look like for the next generation? More of the same but higher out-of-pocket costs
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Aged care financing is a vexed problem for the Australian government. It is already underfunded for the quality the community expects, and costs will increase dramatically. There are also significant concerns about the complexity of the system.
In 2021–22 the federal government spent A$25 billion on aged services for around 1.2 million people aged 65 and over. Around 60% went to residential care (190,000 people) and one-third to home care (one million people).
The final report from the government’s Aged Care Taskforce, which has been reviewing funding options, estimates the number of people who will need services is likely to grow to more than two million over the next 20 years. Costs are therefore likely to more than double.
The taskforce has considered what aged care services are reasonable and necessary and made recommendations to the government about how they can be paid for. This includes getting aged care users to pay for more of their care.
But rather than recommending an alternative financing arrangement that will safeguard Australians’ aged care services into the future, the taskforce largely recommends tidying up existing arrangements and keeping the status quo.
No Medicare-style levy
The taskforce rejected the aged care royal commission’s recommendation to introduce a levy to meet aged care cost increases. A 1% levy, similar to the Medicare levy, could have raised around $8 billion a year.
The taskforce failed to consider the mix of taxation, personal contributions and social insurance which are commonly used to fund aged care systems internationally. The Japanese system, for example, is financed by long-term insurance paid by those aged 40 and over, plus general taxation and a small copayment.
Instead, the taskforce puts forward a simple, pragmatic argument that older people are becoming wealthier through superannuation, there is a cost of living crisis for younger people and therefore older people should be required to pay more of their aged care costs.
Separating care from other services
In deciding what older people should pay more for, the taskforce divided services into care, everyday living and accommodation.
The taskforce thought the most important services were clinical services (including nursing and allied health) and these should be the main responsibility of government funding. Personal care, including showering and dressing were seen as a middle tier that is likely to attract some co-payment, despite these services often being necessary to maintain independence.
The task force recommended the costs for everyday living (such as food and utilities) and accommodation expenses (such as rent) should increasingly be a personal responsibility.
Aged care users will pay more of their share for cooking and cleaning.
Lizelle Lotter/ShutterstockMaking the system fairer
The taskforce thought it was unfair people in residential care were making substantial contributions for their everyday living expenses (about 25%) and those receiving home care weren’t (about 5%). This is, in part, because home care has always had a muddled set of rules about user co-payments.
But the taskforce provided no analysis of accommodation costs (such as utilities and maintenance) people meet at home compared with residential care.
To address the inefficiencies of upfront daily fees for packages, the taskforce recommends means testing co-payments for home care packages and basing them on the actual level of service users receive for everyday support (for food, cleaning, and so on) and to a lesser extent for support to maintain independence.
It is unclear whether clinical and personal care costs and user contributions will be treated the same for residential and home care.
Making residential aged care sustainable
The taskforce was concerned residential care operators were losing $4 per resident day on “hotel” (accommodation services) and everyday living costs.
The taskforce recommends means tested user contributions for room services and everyday living costs be increased.
It also recommends that wealthier older people be given more choice by allowing them to pay more (per resident day) for better amenities. This would allow providers to fully meet the cost of these services.
Effectively, this means daily living charges for residents are too low and inflexible and that fees would go up, although the taskforce was clear that low-income residents should be protected.
Moving from buying to renting rooms
Currently older people who need residential care have a choice of making a refundable up-front payment for their room or to pay rent to offset the loans providers take out to build facilities. Providers raise capital to build aged care facilities through equity or loan financing.
However, the taskforce did not consider the overall efficiency of the private capital market for financing aged care or alternative solutions.
Instead, it recommended capital contributions be streamlined and simplified by phasing out up-front payments and focusing on rental contributions. This echoes the royal commission, which found rent to be a more efficient and less risky method of financing capital for aged care in private capital markets.
It’s likely that in a decade or so, once the new home care arrangements are in place, there will be proportionally fewer older people in residential aged care. Those who do go are likely to be more disabled and have greater care needs. And those with more money will pay more for their accommodation and everyday living arrangements. But they may have more choice too.
Although the federal government has ruled out an aged care levy and changes to assets test on the family home, it has yet to respond to the majority of the recommendations. But given the aged care minister chaired the taskforce, it’s likely to provide a good indication of current thinking.

Is owning a dog good for your health?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Australia loves dogs. We have one of the highest rates of pet ownership in the world, and one in two households has at least one dog.
But are they good for our health?
Mental health is the second-most common reason cited for getting a dog, after companionship. And many of us say we “feel healthier” for having a dog – and let them sleep in our bedroom.
Here’s what it means for our physical and mental health to share our homes (and doonas) with our canine companions.
Pogodina Natalia/Shutterstock Are there physical health benefits to having a dog?
Having a dog is linked to lower risk of death over the long term. In 2019, a systematic review gathered evidence published over 70 years, involving nearly four million individual medical cases. It found people who owned a dog had a 24% lower risk of dying from any cause compared to those who did not own a dog.
Having a dog may help lower your blood pressure through more physical activity. Barnabas Davoti/Pexels Dog ownership was linked to increased physical activity. This lowered blood pressure and helped reduce the risk of stroke and heart disease.
The review found for those with previous heart-related medical issues (such as heart attack), living with a dog reduced their subsequent risk of dying by 35%, compared to people with the same history but no dog.
Another recent UK study found adult dog owners were almost four times as likely to meet daily physical activity targets as non-owners. Children in households with a dog were also more active and engaged in more unstructured play, compared to children whose family didn’t have a dog.
Exposure to dirt and microbes carried in from outdoors may also strengthen immune systems and lead to less use of antibiotics in young children who grow up with dogs.

However, dogs can also pose risks to our physical health. One of the most common health issues for pet owners is allergies.
Dogs’ saliva, urine and dander (the skin cells they shed) can trigger allergic reactions resulting in a range of symptoms, from itchy eyes and runny nose to breathing difficulties.
A recent meta-analysis pooled data from nearly two million children. Findings suggested early exposure to dogs may increase the risk of developing asthma (although not quite as much as having a cat does). The child’s age, how much contact they have with the dog and their individual risk all play a part.
Slips, trips and falls are another risk – more people fall over due to dogs than cats.
Having a dog can also expose you to bites and scratches which may become infected and pose a risk for those with compromised immune systems. And they can introduce zoonotic diseases into your home, including ring worm and Campylobacter, a disease that causes diarrhoea.
For those sharing the bed there is an elevated the risk of allergies and picking up ringworm. It may result in lost sleep, as dogs move around at night.
On the other hand some owners report feeling more secure while co-sleeping with their dogs, with the emotional benefit outweighing the possibility of sleep disturbance or waking up with flea bites.
Proper veterinary care and hygiene practices are essential to minimise these risks.
Many of us don’t just share a home with a dog – we let them sleep in our beds. Claudia Mañas/Unsplash What about mental health?
Many people know the benefits of having a dog are not only physical.
As companions, dogs can provide significant emotional support helping to alleviate symptoms of anxiety, depression and post-traumatic stress. Their presence may offer comfort and a sense of purpose to individuals facing mental health challenges.
Loneliness is a significant and growing public health issue in Australia.
In the dog park and your neighbourhood, dogs can make it easier to strike up conversations with strangers and make new friends. These social interactions can help build a sense of community belonging and reduce feelings of social isolation.
For older adults, dog walking can be a valuable loneliness intervention that encourages social interaction with neighbours, while also combating declining physical activity.
However, if you’re experiencing chronic loneliness, it may be hard to engage with other people during walks. An Australian study found simply getting a dog was linked to decreased loneliness. People reported an improved mood – possibly due to the benefits of strengthening bonds with their dog.
Walking a dog can make it easier to talk to people in your neighbourhood. KPegg/Shutterstock What are the drawbacks?
While dogs can bring immense joy and numerous health benefits, there are also downsides and challenges. The responsibility of caring for a dog, especially one with behavioural issues or health problems, can be overwhelming and create financial stress.
Dogs have shorter lifespans than humans, and the loss of a beloved companion can lead to depression or exacerbate existing mental health conditions.
Lifestyle compatibility and housing conditions also play a significant role in whether having a dog is a good fit.
The so-called pet effect suggests that pets, often dogs, improve human physical and mental health in all situations and for all people. The reality is more nuanced. For some, having a pet may be more stressful than beneficial.
Importantly, the animals that share our homes are not just “tools” for human health. Owners and dogs can mutually benefit when the welfare and wellbeing of both are maintained.

How To Recover Quickly From A Stomach Bug
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
How To Recover Quickly From A Stomach Bug
Is it norovirus, or did you just eat something questionable? We’re not doctors, let alone your doctors, and certainly will not try to diagnose from afar. And as ever, if unsure and/or symptoms don’t go away or do get worse, seek professional medical advice.
That out of the way, we can give some very good general-purpose tips for this one…
Help your immune system to help you
So far as you can, you want a happy healthy immune system. For the most part, we’d recommend the following things:
Beyond Supplements: The Real Immune-Boosters!
…but you probably don’t want to be exercising with a stomach bug, so perhaps sit that one out. Exercise is the preventative; what you need right now is rest.
Hydrate—but watch out
Hydration is critical for recovery especially if you have diarrhea, but drinking too much water too quickly will just make things worse. Great options for getting good hydration more slowly are:
- Peppermint tea
- (peppermint also has digestion-settling properties)
- Ginger tea
- See also: Ginger Does A Lot More Than You Think
- Broths
- These will also help replenish your sodium and other nutrients, gently. Chicken soup for your stomach, and all that. A great plant-based option is sweetcorn soup.
- By broths, we mean clear(ish) water-based soups. This is definitely not the time for creamier soups.
❝Milk and dairy products should be avoided for 24 to 48 hours as they can make diarrhea worse.
Initial dietary choices when refeeding should begin with soups and broth.❞
Source: American College of Gastroenterology
Other things to avoid
Caffeine stimulates the digestion in a way that can make things worse.
Fat is more difficult to digest, and should also be avoided until feeling better.
To medicate or not to medicate?
Loperamide (also known by the brand name Imodium) is generally safe when used as directed.
Click here to see its uses, dosage, side effects, and contraindications
Antibiotics may be necessary for certain microbial infections, but should not be anyone’s first-choice treatment unless advised otherwise by your doctor/pharmacist.
Note that if your stomach bug is not something that requires antibiotics, then taking antibiotics can actually make it worse as the antibiotics wipe out your gut bacteria that were busy helping fight whatever’s going wrong in there:
- Facing a new challenge: the adverse effects of antibiotics on gut microbiota and host immunity
- Antibiotics as major disruptors of gut microbiota
- Microbiotoxicity: antibiotic usage and its unintended harm to the microbiome
A gentler helper
If you want to give your “good bacteria” a hand while giving pathogens a harder time of it, then a much safer home remedy is a little (seriously, do not over do it; we are talking 1–2 tablespoons, or around 20ml) apple cider vinegar, taken diluted in a glass of water.
❝Several studies indicate apple cider vinegar (ACV)’s usefulness in lowering postprandial glycemic response, specifically by slowing of gastric motility❞
(Slowing gastric motility is usually exactly what you want in the case of a stomach bug, and apple cider vinegar)
