The brain is an amazing and powerful organ, with theoretically unlimited potential in some respects. So why doesn’t it feel that way a lot of the time?
The truth is that not only are we often tired, dehydrated, or facing other obvious physiological challenges to peak brain health, but also… We’re simply not making the best use of it!
What Dr. Davis does is outline for us how we can create the conditions for “two awesome hours” of effective mental performance by:
- Recognizing when to most effectively flip the switch on our automatic thinking
- Scheduling tasks based on their “processing demand” and recovery time
- Learning how to direct attention, rather than avoid distractions
- Feeding and moving our bodies in ways that prep us for success
- Identifying what matters in our environment to be at the top of our mental game
Why only two hours? Why not four, or eight, or more?
Well, our brains need recovery time too, so we can’t be “always on” and operating and peak efficiency. But, what we can do is optimize a couple of hours for absolute peak efficiency, and then enjoy the rest of time with lower cognitive-load activities.
Bottom line: if the idea of what you could accomplish if you could just be guaranteed two schedulable hours (your preference when!) of peak cognitive performance per day, then this is a great book for you.

Beyond Supplements: The Real Immune-Boosters!
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 Real Immune-Boosters
What comes to your mind when we say “immune support”? Vitamin C and maybe zinc? Those have their place, but there are things we can do that are a lot more important!
It’s just, these things are not talked about as much, because stores can’t sell them to you
Sleep
One of the biggest difference-makers. Get good sleep! Getting at least 7 hours decent sleep (not lying in bed, not counting interruptions to sleep as part of the sleep duration) can improve your immune system by three or four times.
Put another way, people are 3–4 times more likely to get sick if they get less sleep than that on average.
Check it out: Behaviorally Assessed Sleep and Susceptibility to the Common Cold
Eat an anti-inflammatory diet
In short, for most of us this means lots of whole plant foods (lots of fiber), and limited sugar, flour, alcohol.
For more details, you can see our main feature on this: Keep Inflammation At Bay!
You may wonder why eating to reduce inflammation (inflammation is a form of immune response) will help improve immune response. Put it this way:
If your town’s fire service is called out eleventy-two times per day to deal with things that are not, in fact, fires, then when there is a fire, they will be already exhausted, and will not do their job so well.
Look after your gut microbiota
Additionally, healthy gut microbiota (fostered by the same diet we just described) help keep your body pathogen-free, by avoiding “leaky gut syndrome” that occurs when, for example, C. albicans (you do not want this in your gut, and it thrives on the things we just told you to avoid) puts its roots through your intestinal walls, making holes in them. And through those holes? You definitely do not want bacteria from your intestines going into the rest of your body.

Actually get that moderate exercise
There’s definitely a sweet-spot here, because too much exercise will also exhaust you and deplete your body’s resources. However, the famous “150 minutes per week” (so, a little over 20 minutes per day, or 25 minutes per day with one day off) will make a big difference.
See: Exercise and the Regulation of Immune Functions
Manage your stress levels (good and bad!)
This one swings both ways:
- Acute stress (like a cold shower) is good for immune response. Think of it like a fire drill for your body.
- Chronic stress (“the general everything” persistently stressful in life) is bad for immune response. This is the fire drill that never ends. Your body’s going to know what to do really well, but it’s going to be exhausted already by the time an actual threat hits.

Supplement, yes.
These are far less critical than the above things, but are also helpful. Good things to take include:

8 Signs Of High Cortisol & How To Reverse “Cortisol Face”
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. Shereene Idriss has insights about the facial features that might indicate chronically elevated cortisol levels, and what to do about same:
At face value
Dr. Idriss notes that for most people, this should not be cause for undue concern, although hypercortisolism can also be associated with genetic disorders such as Cushing’s syndrome, as well as prolonged use of certain medication, or the presence of certain tumors. As well as facial swelling, hypercortisolism can also result in other physical changes like acne, weight gain, skin thinning, stretch marks, infections, and hair loss.
As for what to do about it, she recommends addressing lifestyle factors like poor sleep, unhealthy diet, alcohol consumption, and lack of hydration to reduce facial puffiness related to stress. Diet suggestions include incorporating foods rich in magnesium, vitamin C, and omega-3s, such as leafy greens, fatty fish, nuts and seeds, and berries.
She also suggests some supplements to consider, such as ashwagandha, magnesium, omega-3s, and/or l-theanine, but you might want to speak to your doctor/pharmacist to check in case of contraindications per any other conditions you may have, or medications you may be on.

What’s Your Personal Life Expectancy?

Tick Tock… Goes the Death Clock?
This fun little test will ask a few questions about you and your lifestyle, and then make a prediction of your personal life expectancy, based on global statistics from the World Health Organisation.
And then the countdown starts… Literally, it generates a clock for you to see your life-seconds ticking away—this may or may not delight you, but it sure is a curiosity.
Their “Letters” page has a lot of reactions from people who just got their results (spoiler: people’s perspectives on life vary a lot)
Who mostly uses this service? According to their stats page, it’s mostly curious under-45s, with gradually less interest in knowing about it from 45 onwards… until the age of 70, when suddenly everyone wants to know about it again!
So Is It Possible To Pause The Clock On Aging? – Q&A Spotlight Interview
Life extension is sometimes viewed as the domain of the super-rich, and with less than half of Millennials (and almost none of Gen-Z) having retirement plans, often those of us who aren’t super-rich have more mundane (and immediate!) goals than living to 120.
And yet…
Middle class and working class life-extensionists do exist, even if not garnering the same media attention. We think that’s strange—after all, while the whimsies of the super-rich may be entertaining to read about, it’s not nearly as applicable to most people as more relatable stories:
- The twenty-something who gives up smoking and adds (healthier!) years to their life
- The thirty-something who adopts a plant-based diet and is less likely to die of heart disease
- The forty-something who stops drinking, and avoids health conditions and mishaps alike
- The fifty-something who reconsiders their health plan in light of their changing body
- The sixty-something who takes up yoga, or chess, or salsa dancing
- The seventy-something who gets asked what their secret is
- …and so on
But these are ideas, textbook examples. What if we make it more personal?
We interviewed 10 Almonds subscriber and longevity enthusiast Anastasia S., and here’s what she had to say:
Q: What does life extension mean to you, in your life?
A: To me, the key is healthy life extension. People often joke “I don’t want to live longer; the last years are the worst!” but they’re missing the point that after a certain age, those difficulties are coming whether they come at 50 or 70 or 90. Personally, I’d rather keep them at bay if I can.
Q: How do you do that?
A: Firstly, which won’t be a shock: good diet and exercise. Those two things are possibly the biggest active influences on my longevity. I’m vegan, which I don’t think is outright necessary for good health but done right, it can certainly be good. In this house we eat a lot of whole grains, beans, lentils, vegetables in general, nuts too. As for exercise, I do 30–60 minutes of Pilates daily; it’s nothing fancy and it’s just me in my pajamas at home, but it keeps me strong and fit and supple. I also walk everywhere; I don’t even own a car. Beyond that… I don’t drink or smoke (probably the biggest passive influences on my longevity, i.e., things that aren’t there to make it shorter), and I try to take my sleep seriously, making sure to schedule enough time and prepare properly for it.
Q: Take your sleep seriously? How so?
A: Good “sleep hygiene” as some call it—I schedule a little wind-down time before sleep, with no glaring screens or main lights, making a space between my busy day and restful sleep, kicking anything requiring brainpower to the morning, and making a conscious choice not to think more about those things in the meantime. I take care to make my sleeping environment as conducive as possible to good sleep too; I have a good mattress and pillows, I make sure the temperature is cool but cosy. I have a pot of herbal tea on my bedside table—I hydrate a lot.
Q: Do you take any supplements?
A: I do! They’re mostly quite general though, just “covering my bases”, so to speak. I take a daily nootropic stack (a collection of supplements specifically for brain health), too. I buy them in bulk, so they don’t cost so much.
Q: This seems quite a healthy lifestyle! Do you have any vices at all?
A: I definitely drink more coffee than I probably should! But hey, nobody’s perfect. I do love coffee, though, and as vices go, it’s probably not too bad.
Q: How’s it all working out for you? Do you feel younger?
A: I’m 38 and sometimes I feel like a teenager; sometimes I feel like an old lady. But the latter is usually for social reasons, not health-related reasons. I do have streaks of gray in my hair though, and I love that! If people don’t notice my grays, then they often think I’m in my 20s, rather than pushing 40. A little while back, I was stopped in the street by someone wanting to sell me a change of household utilities provider, then she stopped herself mid-sentence and said “Oh but wait, you look a bit too young, never mind”. Most general metrics of health would put me in my 20s.
Q: That’s interesting that you love your gray hairs, for someone who wants to stay young; is it an exception?
A: It’s more that I want to minimize the problems that come with age, and not everything’s a problem. Gray hairs are cool; joint pain, not so much. A long life rich with experiences is cool; memory loss, not so much. So, I try to keep healthy, and wear my years as best I can.
Q: Sounds good to us; good luck with it!
A: Thank you; I do my best!

Seven Things To Do For Good Lung 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.
YouTube Channel Wellness Check is challenging us all to do the following things. They’re framing it as a 30-day challenge, but honestly, there’s nothing here that isn’t worth doing for life
Here’s the list:
- Stop smoking (of course, smoking is bad for everything, but the lungs are one of its main areas of destruction)
- Good posture (a scrunched up chest is not the lungs’ best operating conditions!)
- Regular exercise (exercising your body in different ways exercises your lungs in different ways!)
- Monitor air quality (some environments are much better/worse than others, but don’t underestimate household air quality threats either)
- Avoid respiratory infections (shockingly, COVID is not great for your lungs, nor are the various other respiratory infections available)
- Check your O2 saturation levels (pulse oximeters like this one are very cheap to buy and easy to use)
- Prevent mucus and phlegm from accumulating (these things are there for reasons; the top reason is trapping pathogens, allergens, and general pollutants/dust etc; once those things are trapped, we don’t want that mucus there any more!)

Shedding Some Obesity Myths
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.
Let’s shed some obesity myths!
There are a lot of myths and misconceptions surrounding obesity… And then there are also reactive opposite myths and misconceptions, which can sometimes be just as harmful!
To tackle them all would take a book, but in classic 10almonds style, we’re going to put a spotlight on some of the ones that might make the biggest difference:
True or False: Obesity is genetically pre-determined
False… With caveats.
Some interesting results have been found from twin studies and adoption studies, showing that genes definitely play some role, but lifestyle is—for most people—the biggest factor:
- The body-mass index of twins who have been reared apart
- An adoption study of human obesity
- Using a sibling-adoption design to parse genetic and environmental influences on children’s body mass index
In short: genes predispose; they don’t predetermine. But that predisposition alone can make quite a big difference, if it in turn leads to different lifestyle factors.
But upon seeing those papers centering BMI, let’s consider…
True or False: BMI is a good, accurate measure of health in the context of bodyweight
False… Unless you’re a very large group of thin white men of moderate height, which was the demographic the system was built around.
Bonus information: it was never intended to be used to measure the weight-related health of any individual (not even an individual thin white man of moderate height), but rather, as a tool to look at large-scale demographic trends.
Basically, as a system, it’s being used in a way it was never made for, and the results of that misappropriation of an epidemiological tool for individual health are predictably unhelpful.
To do a deep-dive into all the flaws of the BMI system, which are many, we’d need to devote a whole main feature just to that.
Update: we have now done so!
Here it is: When BMI Doesn’t Measure Up
True or False: Obesity does not meaningfully impact more general health
False… In more ways than one (but there are caveats)
Obesity is highly correlated with increased risk of all-cause mortality, and weight loss, correspondingly, correlates with a reduced risk. See for example:
So what are the caveats?
Let’s put it this way: owning a horse is highly correlated with increased healthy longevity. And while owning a horse may come with some exercise and relaxation (both of which are good for the health), it’s probably mostly not the horse itself that conveys the health benefits… it’s that someone who has the resources to look after a horse, probably has the resources to look after their own health too.
So sometimes there can be a reason for a correlation (it’s not a coincidence!) but the causative factor is partially (or in some cases, entirely) something else.
So how could this play out with obesity?
There’s a lot of discrimination in healthcare settings, unfortunately! In this case, it often happens that a thin person goes in with a medical problem and gets treated for that, while a fat person can go in with the same medical problem and be told “you should try losing some weight”.
Top tip if this happens to you… Ask: “what would you advise/prescribe to a thin person with my same symptoms?”
Other things may be more systemic, for example:
When a thin person goes to get their blood pressure taken, and that goes smoothly, while a fat person goes to get their blood pressure taken, and there’s not a blood pressure cuff to fit them, is the problem the size of the person or the size of the cuff? It all depends on perspective, in a world built around thin people.
That’s a trivial-seeming example, but the same principle has far-reaching (and harmful) implications in healthcare in general, e.g:
- Surgeons being untrained (and/or unwilling) to operate on fat people
- Getting a one-size-fits-all dose that was calculated using average weight, and now doesn’t work
- MRI machines are famously claustrophobia-inducing for thin people; now try not fitting in it in the first place
…and so forth. So oftentimes, obesity will be correlated with a poor healthcare outcome, where the problem is not actually the obesity itself, but rather the system having been set up with thin people in mind.
It would be like saying “Having O- blood type results in higher risks when receiving blood transfusions”, while omitting to add “…because we didn’t stock O- blood”.
True or False: to reduce obesity, just eat less and move more!
False… Mostly.
Moving more is almost always good for most people. When it comes to diet, quality is much more important than quantity. But these factors alone are only part of the picture!
But beyond diet and exercise, there are many other implicated factors in weight gain, weight maintenance, and weight loss, including but not limited to:
- Disrupted sleep
- Chronic stress
- Chronic pain
- Hormonal imbalances
- Physical disabilities that preclude a lot of exercise
- Mental health issues that add (and compound) extra levels of challenge
- Medications that throw all kinds of spanners into the works with their side effects
…and even just those first two things, diet and exercise, are not always so correlated to weight as one might think—studies have found that the difference for exercise especially is often marginal:

Garden Cress vs Watercress – 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 garden cress to watercress, we picked the garden cress.
Why?
While watercress is (rightly!) popularly viewed as a superfood for its nutritional density, the garden variety actually outperforms it.
In terms of macros first, garden cress has more protein, carbs, and fiber, while also having the lower glycemic index. Not that anyone’s getting blood sugar spikes from eating any kind of cress, but still, by the numbers, this is a clear win on the whole for garden cress in the category of macros.
When it comes to vitamins, garden cress has a lot (tens of times) more of vitamins A, B2, B3, B6, B7, B9, C, K, and choline, while watercress has (slightly) more of vitamins B1, B5, and E. An easy win for garden cress.
In the category of minerals, garden cress has more copper, iron, magnesium, manganese, phosphorus, and potassium, while watercress has more calcium. Another clear win for garden cress.
Taking a quick peep at polyphenols in case there’s anything to offset the above, garden cress has 13x more kaempferol (13mg/100g to watercress’s 1mg/100g), and/but watercress, in its favor, has quercetin (at 4mg/100g), which garden cress doesn’t. So, we say this category is also a win for garden cress, but watercress has its merits too.
👆 Let’s clarify: those numbers are all very good, and garden cress’s 13mg/100g kaempferol is absurdly high; most such quotients of most edible plants are orders of magnitude smaller; not to shoehorn in another vegetable, but just to give an example, savoy cabbage, which won on nutritional density vs bok choi recently, has 0.26mg/100g kaempferol and 0.12mg/100g quercetin (which were already very respectable numbers), so you see the difference in cress’s exceptionally generous delivery of these polyphenols!
Adding up the sections makes for an overwhelming win for garden cress!
