Two Awesome Hours – by Dr. Josh Davis

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.

Creatine: Very Different For Young & Old People
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 Deal with Creatine?
Creatine is best-known for its use as a sports supplement. It has a few other uses too, usually in the case of helping to treat (or recover from) specific medical conditions.
What actually is it?
Creatine is an organic compound formed from amino acids (mostly l-arginine and lysine, can be l-methionine, but that’s not too important for our purposes here).
We can take it as a supplement, we can get it in our diet (unless we’re vegan, because plants don’t make it; vertebrates do), and we can synthesize it in our own bodies.
What does it do?
While creatine supplements mostly take the form of creatine monohydrate, in the body it’s mostly stored in our muscle tissue as phosphocreatine, and it helps cells produce adenosine triphosphate, (ATP).
ATP is how energy is kept ready to use by cells, and is cells’ immediate go-to when they need to do something. For this reason, it’s highly instrumental in cell repair and rebuilding—which is why it’s used so much by athletes, especially bodybuilders or other athletes that have a vested interest in gaining muscle mass and enjoying faster recovery times.
See: Creatine use among young athletes
However! For reasons as yet not fully known, it doesn’t seem to have the same beneficial effect after a certain age:
What about the uses outside of sport?
Almost all studies outside of athletic performance have been on animals, despite it being suggested as potentially helpful for many things, including:
- Alzheimer’s disease
- Parkinson’s disease
- Huntington’s disease
- ischemic stroke
- epilepsy
- brain or spinal cord injuries
- motor neuron disease
- memory and brain function in older adults
However, research that’s been done on humans has been scant, if promising:
- A review of creatine supplementation in age-related diseases: more than a supplement for athletes
- Creatine supplementation and cognitive performance in elderly individuals
In short: creatine may reduce symptoms and slow the progression of some neurological diseases, although more research in humans is needed, and words such as “promising”, “potential”, etc are doing a lot of the heavy lifting in those papers we just cited.
Is it safe?
It seems so: Creatine supplementation and health variables: a retrospective study
Nor does it appear to create the sometimes-rumored kidney problems, cramps, or dehydration:
Where can I get it?
You can get it from pretty much any sports nutrition outlet, or you can order online. For example:

Sizing Aside: Are You Wearing The Right Bra For Your Breast Shape?
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 well-known that most women wear incorrectly-fitting bras. Even with careful measurements, buying “off-the-rack” can be a challenge, because the sizing system only takes two measurements, when there are actually many more things to consider. Today’s video demystifies a lot of what else is going on!
For example…
Some of the different breast shapes/arrangements to consider:
- Wide-set breasts: likely to find there’s a bit of a gap between your breasts and the inside (nearest to your sternum) parts of the cups—while spilling out a little at the outside edges. The solution? Bras that offer side-support, to keep things pointing more forwards. Central-closing bras can also help gather things together, and a balconette bra can redistribute things more evenly. Any of these options will be a lot more comfortable.
- Small breasts: bralettes are your friend, keeping things comfortable while not wearing more bra than necessary to do the job (of course going braless is also an option, but we’re talking bra-fitting here, not bra-flinging-off never to be seen again)
- Deflated breasts: often the case for someone who used to have larger breasts, but they lost size for hormonal reasons rather than for weight loss reasons. This often occurs a little while after childbirth, and also happens a lot in menopause. The bra recommendation for this? A push-up plunge bra with ¾ coverage not only provides cleavage if that’s wanted, but also, will keep things much more snug and thus more evenly-distributed. If ever you’ve found yourself needing to adjust yourself every now and gain while out, this will fix that and keep you comfortable for much longer.

Hormone Replacement
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? You can always hit “reply” to any of our emails, or use the feedback widget at the bottom!
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 cant believe 10 Almonds addresses questions. Thanks. I see the word symptoms for menopause. I don’t know what word should replace it but maybe one should be used or is symptom accurate? And I recently read that there was a great disservice for women in my era as they were denied/scared of hormones replacement. Unnecessarily❞
You’d better believe it! In fact we love questions; they give us things to research and write about.
“Symptom” is indeed an entirely justified word to use, being:
- General: any phenomenon or circumstance accompanying something and serving as evidence of it.
- Medical: any phenomenon that arises from and accompanies a particular disease or disorder and serves as an indication of it.
If the question is more whether the menopause can be considered a disease/disorder, well, it’s a naturally occurring and ultimately inevitable change, yes, but then, so is cancer (it’s in the simple mathematics of DNA replication and mutation that, unless a cure for cancer is found, we will always eventually get cancer, if nothing else kills us first).
So, something being natural/inevitable isn’t a reason to not consider it a disease/disorder, nor a reason to not treat it as appropriate if it is causing us harm/discomfort that can be safely alleviated.
Moreover, and semantics aside, it is medical convention to consider menopause to be a medical condition, that has symptoms. Indeed, for example, the US’s NIH (and its constituent NIA, the National Institute of Aging) and the UK’s NHS, both list the menopause’s symptoms, using that word:
- NIA (NIH): What are the signs and symptoms of menopause?
- NHS: Common symptoms of menopause and perimenopause
With regard to fearmongering around HRT, certainly that has been rife, and there were some very flawed (and later soundly refuted) studies a while back that prompted this—and even those flawed studies were not about the same (bioidentical) hormones available today, in any case. So even if they had been correct (they weren’t), it still wouldn’t be a reason to not get treatment nowadays, if appropriate!

Build Strong Feet: Exercises To Strengthen Your Foot & Ankle
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.
A lot depends on the health of our feet, especially when it comes to their strength and stability. But they often get quite neglected, when it comes to maintenance. Here’s how to help your feet keep the rest of your body in good condition:
On a good footing
The foot-specific exercises recommended here include:
- Active toe flexion/extension: curl and extend your toes
- Active toe adduction/abduction: use a towel for feedback this time as you spread your toes
- “Short foot” exercise: create an arch by bringing the base of your big toe towards your heel
- Resisted big toe flexion: use resistance bands; flex your big toe while controlling the others.
- Standing big toe flexion (isometric): press your big toe against an inclined surface as forcefully as you can
- Foot bridge exercise: hold your position with the front part of your feet on an elevated surface, to strengthen the arch.
- Heel raises: which can be progressed from basic to more advanced variations, increasing difficulty
- Ankle movements: dorsiflexion, inversion, etc, to increase mobility
It’s important to also look after your general lower body strength and stability, including (for example) single-leg deadlifts, step-downs, and lunges
Balance and proprioceptive exercises are good too, such as a static or dynamic one-leg balances, progressing to doing them with your eyes closed and/or on unstable surfaces (be careful, of course, and progress to this only when confident).
For more on all of these, an explanation of the anatomy, some other exercises too, and visual demonstrations, enjoy:

Early Bird Or Night Owl? Genes vs Environment
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.
A Sliding Slope?
In Tuesday’s newsletter, we asked you how much control you believe we have over our sleep schedule, and got the above-depicted, below-described, set of responses:
- 45% said “most people can control it; some people with sleep disorders cannot
- 35% said “our genes predispose us to early/late, but we can slide it a bit
- 15% said: “going against our hardwired sleep schedules is a road to ruin”
- 5% said “anyone can adjust their sleep schedule with enough willpower”
You may be wondering: what’s with those single-digit numbers in the graph there? And the answer is: Tuesday’s email didn’t go out at the usual time due to a scheduling mistake (sorry!), which is probably what affected the number of responses (poll response levels vary, but are usually a lot higher than this).
Note: yes, this does mean most people who read our newsletter don’t vote. So, not to sound like a politician on the campaign trail, but… Your vote counts! We always love reading your comments when you add those, too—often they provide context that allow us to tailor what we focus on in our articles
However, those are the responses we got, so here we are!
What does the science say?
Anyone can adjust their sleep with enough willpower: True or False?
False, simply. It’s difficult for most people, but for many people with sleep disorders, it is outright impossible.
In a battle of narcolepsy vs willpower, for example, no amount of willpower will stop the brain from switching to sleep mode when it thinks it’s time to sleep:
❝Narcolepsy is the most common neurological cause of chronic sleepiness. The discovery about 20 years ago that narcolepsy is caused by selective loss of the neurons producing orexins sparked great advances in the field
[There is also] developing evidence that narcolepsy is an autoimmune disorder that may be caused by a T cell-mediated attack on the orexin neurons and explain how these new perspectives can inform better therapeutic approaches.❞
~ Dr. Carrie Mahoney et al. (lightly edited for brevity)
Source: The neurobiological basis of narcolepsy
For further reading, especially if this applies to you or a loved one:
Our genes predispose us to early/late, but we can slide it a bit: True or False?
True! First, about our genes predisposing us:
…and also:
Gene distinguishes early birds from night owls and helps predict time of death
Now, as for the “can slide it a bit”, this is really just a function of the general categories of “early bird” and “night owl” spanning periods of time that allow for a few hours’ wiggle-room at either side.
However, it is recommended to make any actual changes more gradually, with the Sleep Foundation going so far as to recommend 30 minutes, or even just 15 minutes, of change per day:
Sleep Foundation | How to Fix Your Sleep Schedule
Going against our hardwired sleep schedule is a road to ruin: True or False?
False, contextually. By this we mean: our “hardwired” sleep schedule is (for most of us), genetically predisposed but not predetermined.
Also, genetic predispositions are not necessarily always good for us; one would not argue, for example, for avoiding going against a genetic predisposition to addiction.
Some genetic predispositions are just plain bad for us, and genes can be a bit of a lottery.
That said, we do recommend getting some insider knowledge (literally), by getting personal genomics tests done, if that’s a viable option for you, so you know what’s really a genetic trait (and what to do with that information) and what’s probably caused by something else (and what to do with that information):

Gymnema Sylvestre: The “Sugar Destroyer”
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 Leaf That Stops Sugar From “Working”
Gymnema sylvestre, whose botanical name in Greek and Latin means “naked thread of the woods”, and is in various Indian languages referred to be names that translate as “sugar destroyer”, has the most prosaic name in Australia: the Australian cowplant.
In English it’s mostly called by the Greek “gymnema” though, so that’s what we’ll call it here.
You may be wondering: “the sugar destroyer?”
And no, it doesn’t actually destroy sugar. But it does do quite a bit of sugar-related stuff. Here’s the science for it…
Blocks sugar receptors in your tongue
This is what it is most well-known for, and it is a topical effect, so you won’t get this from a pill, but you will get this from the leaves, or from drinking it as a tea made from the leaves.
The effect last several hours, during which time your ability to taste sweetness will be reduced, which not only makes sweet foods less appealing because they’re no longer tasting sweet, but also, once you get used to it, when you actually do taste sweet foods, they will now taste too sweet.
So, it doesn’t just temporarily curb cravings; it offers a long-term escape from such, too.
You may be wondering: “what about artificially sweetened foods and drinks?”
And the answer is: yes, it blocks perception of the sweetness of those too:
Effects of sweetness perception and caloric value of a preload on short term intake ← this study used gymnema as the sweetness-blocker, testing sugary drinks, aspartame-sweetened drinks, and unsweetened drinks
Blocks sugar receptors in the gut, too
Long story short: this slows down the absorption of sugars from the gut, thus resulting in a gentler blood sugar curve, minimizing spikes, and (because of the body’s use of blood sugars as it goes) overall lower blood sugar levels.
Want the long version? Here it is:
Benefits beyond sugar-blocking
It also prevents the accumulation of triglycerides in muscles and the liver, as well as decreasing fatty acid accumulation in the blood. In simpler terms: it lowers LDL (“bad” cholesterol”, including VLDL). As a bonus, it increases HDL (“good” cholesterol) while it’s at it.
The vast majority of the studies for this are on rats and mice though, of which you can see very many listed in the “similar articles” under this systematic review of studies:
A systematic review of Gymnema sylvestre in obesity and diabetes management
We did find one good quality human RCT, testing gymnema along with several other treatments (they found that each worked, and/but using a combination yielded the best results):
(the title says “on weight loss”, but rest assured the study also gives information about its effects on total cholesterol, LDL, HDL, overall triglycerides, and serum leptin levels, as well as excretion of urinary fat metabolites—suffice it to say, they were thorough)
Is it safe?
It has a good safety profile in general, but if you are diabetic, proceed with caution and discuss it with your endocrinologist, since it will be affecting your blood sugar levels and insulin levels. While it’s probably not enough to replace metformin or similar, it is enough that taking it carelessly could result in an unexpected hypo.
Similarly, if you have any heart condition and especially if you are being treated for that with medication, do speak with your cardiologist since its antilipemic action could potentially lower your cholesterol more than expected, and doctors don’t like surprises.
As ever, no list of contraindications will be exhaustive, and we can’t speak for your specific situation, so checking with your pharmacist/doctor is always a good idea.
Want to try some?
We don’t sell it, but here for your convenience is an example product on Amazon ← we’ve linked to a tea version of it so you can enjoy the full effects; if you prefer capsule form, you can click through from there to shop around 😎
Enjoy!
