You probably know the following three things about squats:
- Squatting is great for the health in many ways
- There are many different ways to squat
- Not all of them are correct, and some may even do harm
Dr. Aaron Horschig makes the case for squats being a movement first, and an exercise second. To this end, he takes us on a joint-by-joint tour of the anatomy of squatting, so that we get it right from top to toe.
Or rather: from toe to top, since he starts with the best foundation.
What this means is that if you’ve struggled to squat because you find some discomfort in your ankles, or a weakness in the knees, or you can’t get your back quite right, Dr. Horschig will have a fix for you. He also takes a realistic look about how people’s anatomy varies from person to person, and what differences this makes to how we each should best squat.
The explanations are clear and so are the pictures—we recommend getting the color print edition (linked), as the image quality is better than the black and white and/or Kindle edition.
Bottom-line: squats are one of the single best exercises we can do for our health—but we can miss out on benefits (or even do ourselves harm) if we don’t do them well. This book is a comprehensive reference resource for making sure we get the most out of our squatting ability.

Superfood Soba Noodle Salad
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.
This Japanese dish is packed with nutrients and takes very little preparation time, involving only one cooked ingredient, and a healthy one at that!
You will need
- 8 oz dried soba noodles
- ½ bulb garlic, finely chopped
- 2 tbsp avocado oil
- 2 tsp soy sauce
- ¼ cucumber, cut into thin batons (don’t peel it first)
- ½ carrot, grated (don’t peel it first)
- 6 cherry tomatoes, halved (you wouldn’t peel these, right? Please don’t)
- ½ red onion, finely sliced (ok, this one you can peel first! Please do)
- 1 tbsp chia seeds
- 1 tsp crushed red chili flakes
- Garnish: fresh parsley, chopped
Method
(we suggest you read everything at least once before doing anything)
1) Cook the soba noodles (boil in water for 10 mins or until soft). Rinse with cold water (which lowers the glycemic index further, and also we want them cold anyway) and set aside.
2) Make the dressing by blending the garlic, avocado oil, and soy cauce. Set it aside.
3) Assemble the salad by thoroughly but gently mixing the noodles with the cucumber, carrot, tomatoes, and onion. Add the dressing, the chia seeds, and the chili flakes, and toss gently to combine.
4) Serve, adding the parsley garnish.
Enjoy!

How the stress of playing chess can be fatal
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.
The death of a chess player in the middle of a match at the world’s most prestigious competition may have shocked those who view the game as a relaxing pastime. Kurt Meier, 67, collapsed during his final match in the tournament and died in hospital later that day. But chess, like any other game or sport, can lead to an immense amount of stress, which can be bad for a competitor’s physical health too.
We tend to associate playing sport or games with good health and well-being. And there are a countless number of studies showing playing games has an association with feeling happier. While this argument is true for recreational players, the story can be different for the elite, where success and failure are won and lost by the finest margins and where winning can mean funding and a future, and losing can mean poverty and unemployment. If this is the case, can being successful at a sport or game actually be bad for you?
Competitive anxiety
Elite competition can be stressful because the outcome is so important to the competitors. We can measure stress using a whole range of physiological indicators such as heart rate and temperature, and responses such as changes in the intensity of our emotions.
Emotions provide a warning of threat. So if you feel that achieving your goal is going to be difficult, then expect to feel intense emotions. The leading candidate that signals we are experiencing stress is anxiety, characterised by thoughts of worry, fears of dread about performance, along with accompanying physiological responses such as increased heart rate and sweaty palms. If these symptoms are experienced regularly or chronically, then this is clearly detrimental to health.
This stress response is probably not restricted to elite athletes. Intense emotions are linked to trying to achieve important goals and while it isn’t the only situation where it occurs, it is just very noticeable in sport.
The causes of stress
It makes more sense to focus on what the causes of stress are rather than where we experience it. The principle is that the more important the goal is to achieve, then the greater the propensity for the situation to intensify emotions.
Emotions intensify also by the degree of uncertainty and competing, at whatever level of a sport, is uncertain when the opposition is trying its hardest to win the contest and also has a motivation to succeed. The key point is that almost all athletes at any level can suffer bouts of stress, partly due to high levels of motivation.
A stress response is also linked to how performance is judged and reported. Potentially stressful tasks tend to be ones where performance is public and feedback is immediate. In chess – as with most sporting contests – we see who the winner is and can start celebrating success or commiserating failure as soon as the game is over.
There are many tasks which have similar features. Giving a speech in public, taking an academic examination, or taking your driving test are all examples of tasks that can illicit stress. Stress is not restricted to formal tasks but can also include social tasks. Asking a potential partner for a date, hand in marriage, and meeting the in-laws for the first time can be equally stressful.
Winning a contest or going on a date relate to higher-order goals about how we see ourselves. If we define ourselves as “being a good player” or “being attractive or likeable” then contrasting information is likely to associate with unpleasant emotions. You will feel devastated if you are turned down when asking someone out on a date, for instance, and if this was repeated, it could lead to reduced self-esteem and depression.
The key message here is to recognise what your goals are and think about how important they are. If you want to achieve them with a passion and if the act of achieving them leads to intense and sometimes unwanted emotions, then it’s worth thinking about doing some work to manage these emotions.

Okra vs Asparagus – Which is Healthier?
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.
Our Verdict
When comparing okra to asparagus, we picked the okra.
Why?
Both are great! But…
In terms of macros, okra has more fiber and carbs, making it the more nutrient dense option, for a similar glycemic index.
In the category of vitamins, okra has more of vitamins B1, B3, B6, B9, and C, while asparagus has more of vitamins B2, B5, E, K, and choline, making for a 5:5 tie, with similar margins of difference too. Thus, definitely a tie on vitamins.
When it comes to minerals, okra has more calcium, magnesium, manganese, phosphorus, potassium, and zinc, while asparagus has more copper, iron, and selenium. An easy 6:3 win for okra.
Both of these on-the-cusp-of-being-pungent vegetables have beneficial antioxidant polyphenols (especially various forms of quercetin), but okra has more.
Adding up the sections makes for an overall win for okra, but by all means enjoy either both; diversity is good!

The Emperor’s New Klotho, Or Something More?
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.
Unzipping The Genes Of Aging?
Klotho is an enzyme encoded in humans’ genes—specifically, in the KL gene.
It’s found throughout all living parts of the human body (and can even circulate about in its hormonal form, or come to rest in its membranaceous form), and its subgroups are especially found:
- α-klotho: in the brain
- β-klotho: in the liver
- γ-klotho: in the kidneys
Great! Why do we care?
Klotho, its varieties and variants, its presence or absence, are very important in aging.
Almost every biological manifestation of aging in humans has some klotho-related indicator; usually the decrease or mutation of some kind of klotho.
Which way around the cause and effect go has been the subject of much debate and research: do we get old because we don’t have enough klotho, or do we make less klotho because we’re getting old?
Of course, everything has to be tested per variant and per system, so that can take a while (punctuated by research scientists begging for more grants to do the next one). Given that it’s about aging, testing in humans would take an incredibly long while, so most studies so far have been rodent studies.
The general gist of the results of rodent studies is “reduced klotho hastens aging; increased klotho slows it”.
(this can be known by artificially increasing or decreasing the level of klotho expression, again something easier in mice as it is harder to arrange transgenic humans for the studies)
Here’s one example of many, of that vast set of rodent studies:
Suppression of Aging in Mice by the Hormone Klotho
Relevance for Alzheimer’s, and a science-based advice
A few years ago (2020), an Alzheimer’s study was undertaken; they noted that the famous apolipoprotein E4 (apoE4) allele is the strongest genetic risk factor for Alzheimer’s, and that klotho may be another. FGF21 (secreted by the liver, mostly during fasting) binds to its own receptor (FGFR1) and its co-receptor β-klotho. Since this is a known neuroprotective factor, they wondered whether klotho itself may interact with β-amyloid (Aβ), and found:
❝Aβ can enhance the ability of klotho to draw FGF21 to regions of incipient neurodegeneration in AD❞
In other words: β-amyloid, the substance whose accumulation is associated with neurodegeneration in Alzheimer’s disease, is a mediator in klotho bringing a known neuroprotective factor, FGF21, to the areas of neurodegeneration
In fewer words: klotho calls the firefighters to the scene of the fire
Read more: Alignment of Alzheimer’s disease amyloid β-peptide and klotho
The advice based on this? Consider practicing intermittent fasting, if that is viable for you, as it will give your liver more FGF21-secreting time, and the more FGF21, the more firefighters arrive when klotho sounds the alarm.

…and while you’re at it:
Does intermittent fasting have benefits for our brain?
A more recent (2023) study with a slightly different (but connected) purpose, found results consistent with this:
Longevity factor klotho enhances cognition in aged nonhuman primates
…and, for that matter this (2023) study that found:
Associations between klotho and telomere biology in high stress caregivers
…which looks promising, but we’d like to see it repeated with a sounder method (they sorted caregiving into “high-stress” and “low-stress” depending on whether a child was diagnosed with ASD or not, which is by no means a reliable way of sorting this). They did ask for reported subjective stress levels, but to be more objective, we’d like to see clinical markers of stress (e.g. cortisol levels, blood pressure, heart rate changes, etc).
A very recent (April 2024) study found that it has implications for more aspects of aging—and this time, in humans (but using a population-based cohort study, rather than lab conditions):
Can I get it as a supplement?
Not with today’s technology and today’s paucity of clinical trials, you can’t. Maybe in the future!
However… The presence of senescent (old, badly copied, stumbling and staggering onwards when they should have been killed and eaten and recycled already) cells actively reduces klotho levels, which means that taking supplements that are senolytic (i.e., that kill those senescent cells) can increase serum klotho levels:
Orally-active, clinically-translatable senolytics restore α-Klotho in mice and humans
Ok, what can I take for that?
We wrote about a senolytic supplement that you might enjoy, recently:

How Emotions Are Made – by Dr. Lisa Feldman Barrett
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 previously reviewed Dr. Barrett’s (also good) book Seven And A Half Lessons About The Brain, and this one is very different, and of more practical use:
The main thrust of the book is: the bioessentialist model of emotions is flawed; there is also no Platonic perfect form of any given emotion, and in fact emotions are constructed by the brain as a learned adaptive response.
She argues this from the dual vectors of on the one hand hard sciences of affective neuroscience and clinical psychology, and on the other hand sociology and anthropology.
In the category of criticism: Dr. Barrett, a very well-known and well-respected cognitive neuroscientist, is not an expert on sociology and anthropology, and some of her claims there are verifiably false.
However, most of the book is given over the psychophysiology, which is entirely her thing, and she explains it clearly and simply while backing everything up with mountains of data.
The usefulness of this book is chiefly: if we understand that emotions are not innate and are instead constructed adaptive (and sometimes maladaptive) neurological responses to stimuli and associations, we can set about rewiring things a little in accord with what’s actually more beneficial to us. The book also outlines how.
Bottom line: if you’d like to be able to not merely manage emotions as they are, but also prune and/or grow them from the stem up, then this book provides a robustly scientific approach for doing that.

Dreams: Relevance, Meanings, Interpretations
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.
It’s Q&A Day at 10almonds!
Have a question or a request? We love to hear from you!
In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!
As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!
So, no question/request too big or small
❝I have a question or a suggestion for coverage in your “Psychology Sunday”. Dreams: their relevance, meanings ( if any) interpretations? I just wondered what the modern psychological opinions are about dreams in general.❞
We’ll indeed do that one of these Psychology Sundays! Thanks for suggesting it.
What we can say in advance is that there’s certainly not a single unified scientific consensus yet, but there are two or three prevailing views definitely worth covering, e.g. randomly generated, a by-product of reorganizing information in the brain, or expressions of subconscious thoughts/feelings.
There are also differences between a top-down/bottom-up approach to understanding dreaming, and efforts to tie those two together.
Watch this space!
