Jim Kwik: from broken brain to brain coach
This is Jim Kwik. He suffered a traumatic brain injury as a small child, and later taught himself to read and write by reading comic books. He became fascinated with the process of learning, and in his late 20s he set up Kwik Learning, to teach accelerated learning in classrooms and companies, which he continued until 2009 when he launched his online learning platform. His courses have now been enjoyed by people in 195 countries.
So, since accelerated learning is his thing, you might wonder…
What does he have to share that we can benefit from in the next five minutes?
Three brain exercises to improve memory and concentration
A lot of problems we have with working memory are a case of executive dysfunction, but there are tricks we can use to get our brains into gear and make them cumulatively stronger:
First exercise
You can strengthen your corpus callosum (the little bridge between the two hemispheres of the brain) by performing a simple kinesiological exercise, such as alternating touching your left elbow to your right knee, and touching your right elbow to your left knee.
Do it for about a minute, but the goal here is not a cardio exercise, it’s accuracy!
You want to touch your elbow and opposite knee to each other as precisely as possible each time. Not missing slightly off to the side, not falling slightly short, not hitting it too hard.
Second exercise
Put your hands out in front of you, as though you’re about to type at a keyboard. Now, turn your hands palm-upwards. Now back to where they were. Now palm-upwards again. Got it? Good.
That’s not the exercise, the exercise is:
You’re now going to do the same thing, but do it twice as quickly with one hand than the other. So they’ll still be flipping to the same basic “beat”, put it in musical terms, the tempo on one hand will now be twice that of the other. When you get the hang of that, switch hands and do the other side.
This is again about the corpus callosum, but it’s now adding an extra level of challenge because of holding the two rhythms separately, which is also working the frontal lobe of the cerebral cortex.
The pre-frontal cortex in particular is incredibly important to executive function, self-discipline, and being able to “do” delayed gratification. So this exercise is really important!
Third exercise
This one works the same features of the brain, but most people find it harder. So, consider it a level-up on the previous:
Imagine there’s a bicycle wheel in front of you (as though the bike is facing you at chest-height). Turn the wheel towards you with your hands, one on each side.
Now, do the same thing, but each of your hands is going in the opposite direction. So one is turning the wheel towards you; the other is turning it away from you.
Now, do the same thing, but one hand goes twice as quickly as the other.
Switch sides.
Why is this harder for most people than the previous? Because the previous involved processing discrete (distinct from each other) movements while this one involves analog continuous movements.
It’s like reading an analog clock vs a digital clock, but while using both halves of your brain, your corpus callosum, your pre-frontal cortex, and the motor cortex too.

It’s OK That You’re Not OK – by Megan Devine
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.
Firstly, be aware: this is not a cheerful book. If you’re looking for something to life your mood after a loss, it will not be this.
What, then, will you find? A reminder that grief is also the final translation of love, and not necessarily something to be put aside as quickly as possible—or even ever, if we don’t want to.
Too often, society (and even therapists) will correctly note that no two instances of grief are the same (after all, no two people are, so definitely no two relationships are, so how could two instances of grief be?), but will still expect that if most people can move on quickly from most losses, that you should too, and that if you don’t then there is something pathological at hand that needs fixing.
Part one of the book covers this (and more) in a lot of detail; critics have called it a diatribe against the current status quo in the field of grief.
Part two of the book is about “what to do with your grief”, and addresses the reality of grief, how (and why) to stay alive when not doing so feels like a compelling option, dealing with grief’s physical side effects, and calming your mind in ways that actually work (without trying to sweep your grief under a rug).
Parts three and four are more about community—how to navigate the likely unhelpful efforts a lot of people may make in the early days, and when it comes to those people who can and will actually be a support, how to help them to help you.
In the category of criticism, she also plugs her own (paid, subscription-based) online community, which feels a little mercenary, especially as while community definitely can indeed help, the prospect of being promptly exiled from it if you stop paying, doesn’t.
Bottom line: if you have experienced grief and felt like moving on was the right thing to do, then this book isn’t the one for you. If, on the other hand, your grief feels more like something you will carry just as you carry the love you feel for them, then you’ll find a lot about that here.

What Teas To Drink Before Bed (By Science!)
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.
Which Sleepy Tea?
Herbal “tea” preparations (henceforth we will write it without the quotation marks, although these are not true teas) are popular for winding down at the end of a long day ready for a relaxing sleep.
Today we’ll look at the science for them! We’ll be brief for each, because we’ve selected five and have only so much room, but here goes:
Camomile
Simply put, it works and has plenty of good science for it. Here’s just one example:
❝Noteworthy, our meta-analysis showed a significant improvement in sleep quality after chamomile administration❞
Also this writer’s favourite relaxation drink!
(example on Amazon if you want some)
Lavender
We didn’t find robust science for its popularly-claimed sedative properties, but it does appear to be anxiolytic, and anxiety gets in the way of sleep, so while lavender may not be a sedative, it may calm a racing mind all the same, thus facilitating better sleep:
(example on Amazon if you want some)
Magnolia
Animal study for the mechanism:
Human study for “it is observed to help humans sleep better”:
As you can see from the title, its sedative properties weren’t the point of the study, but if you click through to read it, you can see that they found (and recorded) this benefit anyway
(example on Amazon if you want some)
Passionflower
There’s not a lot of evidence for this one, but there is some. Here’s a small study (n=41) that found:
❝Of six sleep-diary measures analysed, sleep quality showed a significantly better rating for passionflower compared with placebo (t(40) = 2.70, p < 0.01). These initial findings suggest that the consumption of a low dose of Passiflora incarnata, in the form of tea, yields short-term subjective sleep benefits for healthy adults with mild fluctuations in sleep quality.❞
So, that’s not exactly a huge body of evidence, but it is promising.
(example on Amazon if you want some)
Valerian
We’ll be honest, the science for this one is sloppy. It’s very rare to find Valerian tested by itself (or sold by itself; we had to dig a bit to find one for the Amazon link below), and that skews the results of science and renders any conclusions questionable.
And the studies that were done? Dubious methods, and inconclusive results:
Nevertheless, if you want to try it for yourself, you can do a case study (i.e., n=1 sample) if not a randomized controlled trial, and let us know how it goes 🙂
(example on Amazon if you want some)
Summary
- Valerian we really don’t have the science to say anything about it
- Passionflower has some nascent science for it, but not much
- Lavender is probably not soporific, but it is anxiolytic
- Magnolia almost certainly helps, but isn’t nearly so well-backed as…
- Camomile comes out on top, easily—by both sheer weight of evidence, and by clear conclusive uncontroversial results.
Enjoy!

Your Simplest Life – by Lisa Turner
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 probably know how to declutter, and perhaps even do a “unnecessary financial expenditures” audit. So, what does this offer beyond that?
A large portion of this book focuses on keeping our general life in a state of “flow”, and strategies include:
- How to make sure you’re doing the right part of the 80:20 split on a daily basis
- Knowing when to switch tasks, and when not to
- Knowing how to plan time for tasks
- No more reckless optimism, but also without falling foul of Parkinson’s Law (i.e. work expands to fill the time allotted to it)
- Decluttering your head, too!
When it comes to managing life responsibilities in general, Turner is very attuned to generational differences… Including the different challenges faced by each generation, what’s more often expected of us, what we’re used to, and how we probably initially learned to do it (or not).
To this end, a lot of strategies are tailored with variations for each age group. Not often does an author take the time to address each part of their readership like that, and it’s really helpful that she does!
All in all, a great book for simplifying your daily life.

Easing Election Stress & Anxiety
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.
At the time of writing, the US is about to have a presidential election. Most of our readers are Americans, and in any case, what the US does tends to affect most of the world, so certainly many readers in other countries will be experiencing stress and anxiety about it too.
We’re a health science publication, not a political outlet, so we’ll refrain from commenting on any candidates or campaign policies, and we’d also like to be clear we are not urging you to any particular action politically—our focus today is simply about mental health.
First, CBT what can be CBT’d
Cognitive Behavioral Therapy (CBT) is far from a panacea, but it’s often a very good starting point. And when it seems the stakes are high, it’s easy to fall into such cognitive distortions as “crystal ball” and “catastrophization”, that is to say, predicting the future and feeling the impact of that (probably undesired version of the) future, and also feeling like it will be the end of the world.
Recognizing these processes and how they work, is the first step to managing our feelings about them.
Learn more: The Art of Being Unflappable (Tricks For Daily Life)
Next, DBT what can be DBT’d
A lot of CBT hinges on the assumption that our assumptions are incorrect. For example, that our friend does not secretly despise us, that our spouse is not about to leave us, that the symptoms we are experiencing are not cancer, and in this case, that the election outcome will not go badly, and if it does, the consequences will be less severe than imagined.
But… What if our concerns are, in fact, fully justified? Here’s where Dialectic Behavior Therapy (DBT) comes in, and with it, what therapists call “radical acceptance”.
In other words, we accept up front the idea that maybe it’s going to be terrible and that will truly suck, and then either:
- there’s nothing we can reasonably do about it now (so worrying just means you’ll suffer twice), or
- there is something we can reasonably do about it now (so we can go do that thing)
After doing the thing (if appropriate), defer processing the outcome of the election until after the election. There is no point in wasting energy to worry before then. In a broadly two-party system where things are usually close between those two largest parties, there’s something close to a 50% chance of an outcome that’s, at least, not the worst you feared.
Learn more: CBT, DBT, & Radical Acceptance
Lastly, empower yourself with Behavioral Activation (BA)
Whatever the outcome of any given election, the world will keep turning, and the individual battles about any given law or policy or such will continue to go on. That’s not to say an election won’t change things—it will—but there will always still be stuff to do on a grassroots level to make the world a better place, no matter what politician has been elected.
Being involved in doing things on a community level will not only help banish any feelings of despair (and if you got the election outcome you wanted, it’ll help you feel involved), but also, it can give you a sense of control, and can even form a part of the “ikigai” that is often talked about as one of the pillars of healthy longevity.

Krill Oil vs Fish Oil – 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 krill oil to fish oil, we picked the krill oil.
Why?
Both of these products are good sources of omega-3 fatty acids EPA and DHA, and for the specific brand depicted above, in both cases 2 softgels will give you the recommended daily amount (which is generally held to be 250–500mg combined omega-3s per day).
This brand’s fish oil gives more (640mg combined omega-3s per 2 softgels, to the same brand’s krill oil’s 480mg per 2 softgels), but since the krill oil is already in the high end of RDA territory, the excess beyond the RDA is not helpful, and not a huge factor. More quantity is not always better, when the body can only process so much at a time.
However, the krill oil gives some extra things that the fish oil doesn’t:
- Astaxanthin, a “super-antioxidant”
- and neuroprotectant, heart-healthy phospholipids
Additional considerations
We have declared “the winner” based on health considerations only. That’s a sticking point for us in all our writings; we’ll occasionally look at and mention other factors, but we know that health is what you’re here for, so that’s what we’ll always treat as most critical.
However, in case these factors may interest you and/or influence you to one or the other:
• The fish oil is about 30% cheaper financially
• The krill oil is a lot more sustainable environmentallyBack to the health science…

Fast Exercise – by Dr. Michael Mosley & Peta Bee
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 written before about the benefits of High-Intensity Interval Training (HIIT), but there’s more to say than we can fit in a short article!
Dr. Michael Mosley, who hates exercise but knows his stuff when it comes to the benefits, teamed up with Peta Bee, who loves exercise and is a science journalist with degrees in sports science and nutrition, to bring us this book.
In it, we learn a lot about:
- the science of HIIT
- what makes it so different from most kinds of exercise
- exactly what benefits one can expect
…in a very detailed clinical fashion (while still remaining very readable).
By “very detailed clinical fashion”, here we mean “one minute of this kind of exercise this many times per week over this period of time will give this many extra healthy life-years”, for example, along with lots of research to back numbers, and explanations of the mechanisms of action (e.g. reducing inflammatory biomarkers of aging, increasing cellular apoptosis, improving cardiometabolic stats for reduced CVD risk, and many things)
There’s also time/space given over to exactly what to do and how to do it, giving enough options to suit personal tastes/circumstances.
Bottom line: if you’d like to make your exercise work a lot harder for you while you spend a lot less time working out, then this book will help you do just that!
Click here to check out Fast Exercise, and enjoy the benefits!
