Most of us learned to walk at a very young age and probably haven’t thought much about it since, except perhaps in a case where some injury made it difficult.

Annabel Streets provides a wonderful guide to not just taking up (or perhaps reclaiming) the joy of walking, but also the science of it in more aspects than most of us have considered:

  • The physical mechanics of walking—what’s best?
  • Boots or shoes? Barefoot?
  • Roads, grass, rougher vegetation… Mud?
  • Flora & fauna down to the microbiota that affect us
  • How much walking is needed, to be healthy?
  • Is there such a thing as too much walking?
  • What are the health benefits (or risks) of various kinds of weather?
  • Is it better to walk quickly or to walk far?
  • What about if we’re carrying some injury?
  • What’s going on physiologically when we walk?
  • And so much more…

Streets writes with a captivating blend of poetic joie-de-vivre coupled with scientific references.

One moment the book is talking about neuroradiology reports of NO-levels in our blood, the impact of Mycobacterium vaccae, and the studied relationship between daily steps taken and production of oligosaccharide 3′-sialyllactose, and the next it’s all:

“As if the newfound lightness in our limbs has crept into our minds, loosening our everyday cares and constraints…”

And all in all, this book helps remind us that sometimes, science and a sense of wonder can and do (and should!) walk hand-in-hand.

  • Planning Ahead For Better Sleep

    Sleep: 6 Dimensions And 24 Hours!

    A woman with dark hair, planning ahead for better sleep, against a white background.

    This is Dr. Lisa Matricciani, a sleep specialist from the University of South Australia, where she teaches in the School of Health Sciences.

    What does she want us to know?

    Healthy sleep begins before breakfast

    The perfect bedtime routine is all well and good, but we need to begin much earlier in the day, Dr. Matricciani advises.

    Specifically, moderate to vigorous activity early in the day plays a big part.

    Before breakfast is best, but even midday/afternoon exercise is associated with better sleep at night.

    Plan your time well to sleep—but watch out!

    Dr. Matricciani’s research has also found that while it’s important to plan around getting a good night’s sleep (including planning when this will happen), allocating too much time for sleep results in more restless sleep:

    ❝Allocating more time to sleep was associated with earlier sleep onsets, later sleep offsets, less efficient and more consistent sleep patterns for both children and adults.❞

    ~ Dr. Lisa Matricciani et al.

    (this was very large study involving 1,168 children and 1.360 adults, mostly women)

    What counts as good sleep quality? Is it just efficiency?

    It is not! Although that’s one part of it. You may remember our previous main feature:

    The 6 Dimensions Of Sleep (And Why They Matter)

    Dr. Matricciani agrees:

    ❝Everyone knows that sleep is important. But when we think about sleep, we mainly focus on how many hours of sleep we get, when we should also be looking at our sleep experience as a whole❞

    ~ Dr. Lisa Matricciani

    So, time to get planning for the best sleep!

  • What’s the difference between Alzheimer’s and dementia?

    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’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.

    Changes in thinking and memory as we age can occur for a variety of reasons. These changes are not always cause for concern. But when they begin to disrupt daily life, it could indicate the first signs of dementia.

    Another term that can crop up when we’re talking about dementia is Alzheimer’s disease, or Alzheimer’s for short.

    So what’s the difference?

    Lightspring/Shutterstock

    What is dementia?

    Dementia is an umbrella term used to describe a range of syndromes that result in changes in memory, thinking and/or behaviour due to degeneration in the brain.

    To meet the criteria for dementia these changes must be sufficiently pronounced to interfere with usual activities and are present in at least two different aspects of thinking or memory.

    For example, someone might have trouble remembering to pay bills and become lost in previously familiar areas.

    It’s less-well known that dementia can also occur in children. This is due to progressive brain damage associated with more than 100 rare genetic disorders. This can result in similar cognitive changes as we see in adults.

    So what’s Alzheimer’s then?

    Alzheimer’s is the most common type of dementia, accounting for about 60-80% of cases.

    So it’s not surprising many people use the terms dementia and Alzheimer’s interchangeably.

    Changes in memory are the most common sign of Alzheimer’s and it’s what the public most often associates with it. For instance, someone with Alzheimer’s may have trouble recalling recent events or keeping track of what day or month it is.

    We still don’t know exactly what causes Alzheimer’s. However, we do know it is associated with a build-up in the brain of two types of protein called amyloid-β and tau.

    While we all have some amyloid-β, when too much builds up in the brain it clumps together, forming plaques in the spaces between cells. These plaques cause damage (inflammation) to surrounding brain cells and leads to disruption in tau. Tau forms part of the structure of brain cells but in Alzheimer’s tau proteins become “tangled”. This is toxic to the cells, causing them to die. A feedback loop is then thought to occur, triggering production of more amyloid-β and more abnormal tau, perpetuating damage to brain cells.

    Alzheimer’s can also occur with other forms of dementia, such as vascular dementia. This combination is the most common example of a mixed dementia.

    Vascular dementia

    The second most common type of dementia is vascular dementia. This results from disrupted blood flow to the brain.

    Because the changes in blood flow can occur throughout the brain, signs of vascular dementia can be more varied than the memory changes typically seen in Alzheimer’s.

    For example, vascular dementia may present as general confusion, slowed thinking, or difficulty organising thoughts and actions.

    Your risk of vascular dementia is greater if you have heart disease or high blood pressure.

    Frontotemporal dementia

    Some people may not realise that dementia can also affect behaviour and/or language. We see this in different forms of frontotemporal dementia.

    The behavioural variant of frontotemporal dementia is the second most common form (after Alzheimer’s disease) of younger onset dementia (dementia in people under 65).

    People living with this may have difficulties in interpreting and appropriately responding to social situations. For example, they may make uncharacteristically rude or offensive comments or invade people’s personal space.

    Semantic dementia is also a type of frontotemporal dementia and results in difficulty with understanding the meaning of words and naming everyday objects.

    Dementia with Lewy bodies

    Dementia with Lewy bodies results from dysregulation of a different type of protein known as α-synuclein. We often see this in people with Parkinson’s disease.

    So people with this type of dementia may have altered movement, such as a stooped posture, shuffling walk, and changes in handwriting. Other symptoms include changes in alertness, visual hallucinations and significant disruption to sleep.

    Do I have dementia and if so, which type?

    If you or someone close to you is concerned, the first thing to do is to speak to your GP. They will likely ask you some questions about your medical history and what changes you have noticed.

    Sometimes it might not be clear if you have dementia when you first speak to your doctor. They may suggest you watch for changes or they may refer you to a specialist for further tests.

    There is no single test to clearly show if you have dementia, or the type of dementia. A diagnosis comes after multiple tests, including brain scans, tests of memory and thinking, and consideration of how these changes impact your daily life.

    Not knowing what is happening can be a challenging time so it is important to speak to someone about how you are feeling or to reach out to support services.

    Dementia is diverse

    As well as the different forms of dementia, everyone experiences dementia in different ways. For example, the speed dementia progresses varies a lot from person to person. Some people will continue to live well with dementia for some time while others may decline more quickly.

    There is still significant stigma surrounding dementia. So by learning more about the various types of dementia and understanding differences in how dementia progresses we can all do our part to create a more dementia-friendly community.

    The National Dementia Helpline (1800 100 500) provides information and support for people living with dementia and their carers. To learn more about dementia, you can take this free online course.

  • Scarcity Brain – by Michael Easter

    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.

    After a brief overview of theevolutionary psychology underpinnings of the scarcity brain, the author grounds the rest of this book firmly in the present. He explains how the scarcity loop hooks us and why we crave more, and what factors can increase or lessen its hold over us.

    As for what things we are wired to consider “potentially scarce any time now” no matter how saturated we are in them, he looks at an array of categories, each with their nuances. From the obvious such as “food” and “stuff“, to understandable “information” and “happiness“, to abstractions like “influence“, he goes to many sources—experts of various kinds from around the world—to explore how we can know “how much is enough”, and—which can be harder—act accordingly.

    The key, he argues, is not in simply wanting less, but in understanding why we crave more in the first place, get rid of our worst habits, and use what we already have, better.

    Bottom line: if you feel a gnawing sense of needing more “to be on the safe side”, this book can help you to be a little more strategic (and at the same time, less stressed!) about that.

    The title (and subtitle) is, of course, an appeal to vanity. However, the first-listed author is well-known as “The Glute Guy”, and he takes this very seriously, not just for aesthetic reasons but also for practical reasons.

    After all, when it comes to posture and stability, a lot rests on our hips, and hips, well, they rest on our butt and thighs. What’s more, the gluteus maximus is the largest muscle in the human body, so really, is it a good one to neglect? Probably not, and your lower back will definitely thank you for keeping your glutes in good order, too.

    That said, while it’s a focal point, it’s not the be-all-and-end-all, and this book does cover the whole body.

    The book takes the reader from “absolute beginner” to “could compete professionally”, with clearly-illustrated and well-described exercises. We also get a strong “crash course” in the relevant anatomy and physiology, and even a chapter on nutrition, which is a lot better than a lot of exercise books’ efforts in that regard.

    For those who like short courses, this book has several progressive 12-week workout plans that take the reader from a very clear starting point to a very clear goal point.

    Another strength of the book is that while a lot of exercises expect (and require) access to a gym, there are also whole sections of “at home / bodyweight” exercises, including 12-week workout plans for such, as described above.

    Bottom line: there’s really nothing bad that this reviewer can find to say about this one—highly recommendable to any woman who wants to get strong while keeping a feminine look.

  • The Bare-Bones Truth About Osteoporosis

    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.

    In yesterday’s issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:

    The Bare-bones Truth About Osteoporosis

    In yesterday’s issue of 10almonds, we asked you “at what age do you think it’s important to start worrying about osteoporosis?”, and here’s the spread of answers you gave us:

    At first glance it may seem shocking that a majority of respondents to a poll in a health-focused newsletter think it’ll never be an issue worth worrying about, but in fact this is partly a statistical quirk, because the vote of the strongest “early prevention” crowd was divided between “as a child” and “as a young adult”.

    This poll also gave you the option to add a comment with your vote. Many subscribers chose to do so, explaining your choices… But, interestingly, not one single person who voted for “never” had any additional thoughts to add.

    We loved reading your replies, by the way, and wish we had room to include them here, because they were very interesting and thought-provoking.

    Let’s get to the myths and facts:

    Top myth: “you will never need to worry about it; drink a glass of milk and you’ll be fine!”

    The body is constantly repairing itself. Its ability to do that declines with age. Until about 35 on average, we can replace bone mineral as quickly as it is lost. After that, we lose it by up to 1% per year, and that rate climbs after 50, and climbs even more steeply for those who go through (untreated) menopause.

    Losing 1% per year might not seem like a lot, but if you want to live to 100, there are some unfortunate implications!

    About that menopause, by the way… Because declining estrogen levels late in life contribute significantly to osteoporosis, hormone replacement therapy (HRT) may be of value to many for the sake of bone health, never mind the more obvious and commonly-sought benefits.

    On the topic of that glass of milk…

    • Milk is a great source of calcium, which is useless to the body if you don’t also have good levels of vitamin D and magnesium.
    • People’s vitamin D levels tend to directly correlate to the level of sun where they live, if supplementation isn’t undertaken.
    • Plant-based milks are usually fortified with vitamin D (and calcium), by the way.
    • Most people are deficient in magnesium, because green leafy things don’t form as big a part of most people’s diets as they should.

    See also: An update on magnesium and bone health

    Next most common myth: “bone health is all about calcium”

    We spoke a little above about the importance of vitamin D and magnesium for being able to properly use that. But potassium is also critical:

    Read more: The effects of potassium on bone health

    While we’re on the topic…

    People think of collagen as being for skin health. And it is important for that, but collagen’s benefits (and the negative effects of its absence) go much deeper, to include bone health. We’ve written about this before, so rather than take more space today, we’ll just drop the link:

    Let’s Bust Some Myths!

    It’s too late after puberty, hormones won’t change xyz

    While yes, many adult trans people dearly wish they’d been able to medically transition before going through the “wrong” puberty, the truth is that a lot of changes will still occur later… even to “unchangeable” things like the skeleton.

    The body is remaking itself throughout life, and hormones tell it how to do that. Some parts are just quicker or slower than others. Also: the skeleton is pulled-on constantly by our muscles, and in a battle of muscle vs bone, muscle will always win over time.

    Examples of this include:

    • trans men building bigger bones to support their bigger muscles
    • trans women getting smaller, with wider hips and a pelvic tilt

    Trans people have sporting advantages

    Assuming at least a year’s cross-sex hormonal treatment, there is no useful advantage to being trans when engaging in a sport. There are small advantages and disadvantages (which goes for any person’s body, really). For example:

    • Trans women will tend to be taller than cis women on average…
      • …but that larger frame is now being powered by smaller muscles, because they shrink much quicker than the skeleton.
    • Trans men taking T are the only athletes allowed to take testosterone…
      • …but they will still often be smaller than their fellow male competitors, for example.

    Read: Do Trans Women Athletes Have Advantages? (A rather balanced expert overview, which does also cover trans men)

    There’s a trans population explosion; it’s a social contagion epidemic!

    Source for figures: The Overall Rate Of Left-Handedness (Researchgate)

    Left-handed people used to make up around 3% of the population… Until the 1920s, when that figure jumped sharply upwards, before plateauing at around 12% in around 1960, where it’s stayed since. What happened?! Simple, schools stopped forcing children to use their right hand.

    Today, people ask for trans healthcare because they know it exists! Decades ago, it wasn’t such common knowledge.

    The same explanation can be applied to other “population explosions” such as for autism and ADHD.

    Fun fact: Mt. Everest was “discovered” in 1852, but scientists suspect it probably existed long before then! People whose ancestors were living on it long before 1852 also agree. Sometimes something exists for a long time, and only comes to wider public awareness later.

    Transgender healthcare is too readily available, especially to children!

    To believe some press outlets, you’d think:

    • HRT is available from school vending machines,
    • kids can get a walk-in top surgery at recess,
    • and there’s an after-school sterilization club.

    In reality, while availability varies from place to place, trans healthcare is heavily gatekept. Even adults have trouble getting it, often having to wait years and/or pay large sums of money… and get permission from a flock of doctors, psychologists, and the like. For those under the age of 18, it’s almost impossible in many places, even with parental support.

    Puberty-blockers shouldn’t be given to teenagers, as the effects are irreversible

    Quick question: who do you think should be given puberty-blockers? For whom do you think they were developed? Not adults, for sure! They were not developed for trans teens either, but for cis pre-teens with precocious puberty, to keep puberty at bay, to do it correctly later. Nobody argues they’re unsafe for much younger cis children, and only object when it’s trans teens.

    They’re not only safe and reversible, but also self-reversing. Stop taking them, and the normally scheduled puberty promptly ensues by itself. For trans kids, the desired effect is to buy the kid time to make an informed and well-considered decision. After all, the effects of the wrong puberty are really difficult to undo!

    A lot of people rush medical transition and regret it!

    Trans people wish it could be rushed! It’s a lot harder to get gender-affirming care as a trans person, than it is to get the same (or comparable) care as a cis person. Yes, cis people get gender-affirming care, from hormones to surgeries, and have done for a long time.

    As for regret… Medical transition has around a 1% regret rate. For comparison, hip replacement has a 4.8% regret rate and knee replacement has a 17.1% regret rate.

    A medical procedure with a 99% success rate would generally be considered a miracle cure!
