- We all know sleep is important.
- We all know that without it, we’ll suffer rapid cognitive decline.
- We all know approximately what we’re supposed to do to get good sleep.
So what does this book bring to the table? Mostly, deep understanding (written from the perspective of a career in sleep science) presented in such a way as to be applicable, by you, in your life. Stop sabotaging yourself before you even get out of your bed in the morning!
Hustle culture champions early mornings and late nights, and either or both of those might be difficult to avoid. But to make what you’re doing sustainable, you’re going to have to make some informed decisions about looking after your #1 asset—you!
Dr. Walker writes in a clear and accessible fashion, without skimping on the hard science, and always with practical application in mind. All in all, we can’t recommend this one enough.

Body by Science – by Dr. Doug McGuff & John Little
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 idea that you’ll get a re-sculpted body at 12 minutes per week is a bold claim, isn’t it? Medical Doctor Doug McGuff and bodybuilder John Little team up to lay out their case. So, how does it stand up to scrutiny?
First, is it “backed by rigorous research” as claimed? Yes… with caveats.
The book uses a large body of scientific literature as its foundation, and that weight of evidence does support this general approach:
- Endurance cardio isn’t very good at burning fat
- Muscle, even just having it without using it much, burns fat to maintain it
- To that end, muscle can be viewed as a fat-burning asset
- Muscle can be grown quickly with short bursts of intense exercise once per week
Why once per week? The most relevant muscle fibers take about that long to recover, so doing it more often will undercut gains.
So, what are the caveats?
The authors argue for slow reps of maximally heavy resistance work sufficient to cause failure in about 90 seconds. However, most of the studies cited for the benefits of “brief intense exercise” are for High Intensity Interval Training (HIIT). HIIT involves “sprints” of exercise. It doesn’t have to be literally running, but for example maxing out on an exercise bike for 30 seconds, slowing for 60, maxing out for 30, etc. Or in the case of resistance work, explosive (fast!) concentric movements and slow eccentric movements, to work fast- and slow-twitch muscle fibers, respectively.
What does this mean for the usefulness of the book?
- Will it sculpt your body as described in the blurb? Yes, this will indeed grow your muscles with a minimal expenditure of time
- Will it improve your body’s fat-burning metabolism? Yes, this will indeed turn your body into a fat-burning machine
- Will it improve your “complete fitness”? No, if you want to be an all-rounder athlete, you will still need HIIT, as otherwise anything taxing your under-worked fast-twitch muscle fibers will exhaust you quickly.
Bottom line: read this book if you want to build muscle efficiently, and make your body more efficient at burning fat. Best supplemented with at least some cardio, though!

Altered Traits – by Dr. Daniel Goleman & Dr. Richard Davidson
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 know that meditation helps people to relax, but what more than that?This book explores the available science.
We say “explore the available science”, but it’d be remiss of us not to note that the authors have also expanded the available science, conducting research in their own lab.
From stress tests and EEGs to attention tests and fMRIs, this book looks at the hard science of what different kinds of meditation do to the brain. Not just in terms of brain state, either, but gradual cumulative anatomical changes, too. Powerful stuff!
The style is very pop-science in presentation, easily comprehensible to all. Be aware though that this is an “if this, then that” book of science, not a how-to manual. If you want to learn to meditate, this isn’t the book for that.
Bottom line: if you’d like to understand more about how different kinds of meditation affect the brain differently, this is the book for you.

How Does Fat Actually Leave The Body? Where Does It Go?
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.
Fat loss is often misunderstood, with many believing it simply “vanishes” through exercise, is simply excreted in solid form in the bathroom, or materially disappears when converted for energy. However, the principle of conservation of mass plays out here, in that the mass in fat doesn’t disappear—it changes its arrangement:
In and out
Fat is composed of carbon, hydrogen, and oxygen atoms, with an example common form of fat in the body being C55H104O6. That’s a lot of Cs and Hs, and a few Os.
When fat leaves the body, it has been primarily converted into carbon dioxide (CO2) and water (H2O).
According to a 2014 study by the University of South Wales, 84% of the mass of fat exits the body as CO2 exhaled through breathing, while 16% leaves as water through sweat, urine, and other bodily fluids (all of which contain H2O).
You’ll notice there are a lot more Os going out, proportionally, than we originally had in the C55H104O6. For this reason, the process requires oxygen intake; for every 10 kilograms of fat burned, by simple mathematics the body needs around 29 kilograms of oxygen.
Physical activity plays a crucial role in fat loss. When the body exerts itself, it naturally switches to a higher oxygen metabolism necessary for fat breakdown. This effect is amplified during intermittent fasting, which boosts human growth hormone (HGH), a hormone that aids in fat metabolism.
However, simply hyperventilating won’t work; exercise is essential to activate these processes—otherwise it’s just a case of oxygen in, oxygen out, without involving the body’s chemical energy reserves.
Consequently, one of the best diet-and-exercise combinations for fat loss is intermittent fasting with high-intensity interval training.
And, as for what to eat, this video says raw vegan, but honestly, that’s not scientific consensus. However, a diet rich in unprocessed (or minimally processed) fruits and vegetables definitely is where it’s at, with the plant-heavy Mediterranean diet generally scoring highest—which can be further improved by skipping the mammals to make it pesco-Mediterranean. Current scientific consensus does not give any extra benefits for also omitting moderate consumption of fish and fermented dairy products, so include those if you want, or skip those if you prefer.

The Bates Method for Better Eyesight Without Glasses − by Dr. William Bates
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 is a very popular book and method, albeit not a very new one. It was first published in 1920; self-published by Dr. Bates, as the American Medical Association (AMA) considered it quackery.
Of course, our understanding of eyesight has improved a lot in the past 100 years, so, with the benefit of an extra century of ophthalmological research, who was on the right side of history?
As it turns out, all of Dr. Bates’ ideas have been firmly disproven, and eyes simply do not work the way he thought they do (for example, he believed that rather than adjusting the lens for focus, the muscles around the eye elongate the eyeball; this absolutely is not how focusing works, and while how much those muscles squeeze the eye does vary depending on some physiological factors, there are no known exercises that can change them).
Nevertheless, for the interested, his techniques include such things as:
- putting pressure on one’s eyes with one’s hands (which can increase glaucoma risk)
- visualization, rather than actual viewing, of an eye chart (this is ironic, because the book cover promises that an eye chart is included; it is not; perhaps it was hoped that we would visualize it more vividly and thus see it?)
- sunning, which is not only directly looking at the sun, but also using a burning glass to increase the focus of the sunlight onto one’s eye (please do not do this under any circumstances)
His primary thesis in this work, though, is that eyesight problems of all kinds (from short- and long-sightedness, to more serious things like cataracts and glaucoma) are caused by the tension produced by reading books, so relaxation exercises are his prescription for this.
The style is characteristic of its era and then some; bold claims are made with no evidence, there are no references, and the text is (ironically, given his opinions on tension being produced by reading books) quite dense. It certainly doesn’t lend itself well to skimming, for example, because something critical can easily be buried in a wall of text of what is, honestly, mostly waffle.
Bottom line: if you’d like to improve your eyesight and reduce your dependency on glasses, then we absolutely cannot recommend this book, and would direct you instead to Vision for Life, Revised Edition – by Dr. Meir Schneider, which is much more consistent with actual science.
Click here if you are, nonetheless, curious about Dr. Bates’ book and wish to check it out!
PS: Dr. Bates certainly was an interesting fellow; he disappeared mysteriously, but was found working as a medical assistant a few weeks later by his wife, whom he now claimed to not recognize. Then he disappeared again two days later (his wife never found him, this time, despite trying for many years), only to show up again, 13 years later, shortly after his wife’s death, whereupon he remarried (to his long-time personal assistant). None of this has anything to do with his fascinating opinions on eyesight, but it’s a story worth mentioning.

Daily, Weekly, Monthly: Habits Against Aging
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.
Dr. Anil Rajani has advice on restoring/retaining youthfulness. Two out of three of the sections are on skincare specifically, which may seem a vanity, but it’s also worth remembering that our skin is a very large and significant organ, and makes a big difference for the rest of our physical health, as well as our mental health. So, it’s worthwhile to look after it:
The recommendations
Daily: meditation practice
Meditation reduces stress, which reduction in turn protects telomere length, slowing the overall aging process in every living cell of the body.
Weekly: skincare basics
Dr. Rajani recommends a combination of retinol and glycolic acid. The former to accelerate cell turnover, stimulate collagen production, and reduce wrinkles; the latter, to exfoliate dead cells, allowing the retinol to do its job more effectively.
We at 10almonds would like to add: wearing sunscreen with SPF50 is a very good thing to do on any day that your phone’s weather app says the UV index is “moderate” or higher.
Monthly: skincare extras
Here are the real luxuries; spa visits, microneedling (stimulates collagen production), and non-ablative laser therapy. He recommends creating a home spa if possible for monthly skincare treatments, investing in high-quality devices for long-term benefits.

5 Things You Can Change About Your Personality (But: Should You?)
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.
There are many personality-typing systems that, with varying degrees of validity*, aim to describe a person’s personality.
*and often pseudoscience:
- sometimes obviously so like astrology
- sometimes dressed up in clinical words like the Meyers-Briggs
- sometimes openly, per “this is not science but you may find it useful to frame things this way”, like the Enneagram
There is currently one kind of personality-typing system (with some minor variations) that is used in the actual field of clinical psychology, specifically under the umbrella of “trait theory”, and that is…
The “Big Five” personality traits
Also called the OCEAN or CANOE model, based on its 5 components:
- openness to experience: inventive/curious rather than consistent/cautious
- conscientiousness: efficient/organized rather than extravagant/careless
- extroversion: outgoing/energetic rather than solitary/reserved
- agreeableness: friendly/compassionate rather than critical/judgmental
- neuroticism: sensitive/nervous rather than resilient/confident
The latter (neuroticism) is not to be confused with neurosis, which is very different and beyond the scope of today’s article.
Note that some of these seem more positive/negative than others at a glance, but really, any of these could be a virtue or a vice depending on specifics or extremity.
For scientific reference, here’s an example paper:
The Big Five Personality Factors and Personal Values
Quick self-assessment
There are of course many lengthy questionnaires for this, but in the interests of expediency:
Take a moment to rate yourself as honestly as you can, on a scale of 1–10, for each of those components, with 10 being highest for the named trait.
For example, this writer gives herself: O7, C6, E3, A8, N2 (in other words I’d say I’m fairly open, moderately conscientious, on the reserved side, quite agreeable, and quite resilient)
Now, put your rating aside (in your phone’s notes app is fine, if you hadn’t written it down already) and forget about it for the moment, because we want you to do the next exercise from scratch.
Who would you be, at your best?
Now imagine your perfect idealized self, the best you could ever be, with no constraints.
Take a moment to rate your idealized self’s personality, on a scale of 1–10, for each of those components, with 10 being highest for the named trait.
For example, this writer picks: O9, C10, E5, A8, N1.
Maybe this, or maybe your own idealized self’s personality, will surprise you. That some traits might already be perfect for you already; others might just be nudged a little here or there; maybe there’s some big change you’d like. Chances are you didn’t go for a string of 10s or 1s (though if you did, you do you; there are no wrong answers here as this one is about your preferences).
We become who we practice being
There are some aspects of personality that can naturally change with age. For example:
- confidence/resilience will usually gradually increase with age due to life experience (politely overlook teenagers’ bravado; they are usually a bundle of nerves inside, resulting in the overcompensatory displays of confidence)
- openness to experience may decrease with age, as we can get into a rut of thinking/acting a certain way, and/or simply consciously decide that our position on something is already complete and does not need revision.
But, we can decide for ourselves how to nudge our “Big Five” traits, for example:
- We can make a point of seeking out new experiences, and considering new ideas, or develop strategies for reining ourselves in
- We can use systems to improve our organization, or go out of our way to introduce a little well-placed chaos
- We can “put ourselves out there” socially, or make the decision to decline more social invitations because we simply don’t want to
- We can make a habit of thinking kindly of others and ourselves, or we can consciously detach ourselves and look on the cynical side more
- We can build on our strengths and eliminate our weaknesses, or lean into uncomfortable emotions
Some of those may provoke a “why would anyone want to…?” response, but the truth is we are all different. An artist and a police officer may have very different goals for who they want to be as a person, for example.
Interventions to change personality can and do work:
A systematic review of personality trait change through intervention
There are many ways to go about “being the change we want to see” in ourselves, and yes there can be a degree of “fake it until you make it” if that works for you, but it doesn’t have to be so. It can also simply be a matter of setting yourself reminders about the things that are most important to you.
Writer’s example: pinned above my digital workspace I have a note from my late beloved, written just under a week before death. The final line reads, “keep being the good person that you are” (on a human level, the whole note is uplifting and soothing to me and makes me smile and remember the love we shared; or to put it in clinical terms, it promotes high agreeableness, low neuroticism).
Other examples could be a daily practice of gratitude (promotes lower neuroticism), or going out of your way to speak to your neighbors (promotes higher extraversion), signing up for a new educational course (promotes higher openness) or downloading a budgeting app (promotes higher conscientiousness).
In short: be the person you want to be, and be that person deliberately, because you can.
