How To Engage Your Whole Brain

The Stroke Of Insight That Nobody Wants
This is Dr. Jill Bolte Taylor. She’s a neuroanatomist, who, at the age of 37 (when she was a post-doctoral fellow at Harvard Medical School), had what she refers to as her “stroke of insight”.
That is to say, she had a massive stroke, and after a major brain surgery to remove a clot the size of a golf ball, she spent the next 8 years re-learning to do everything.
Whereas previously she’d been busy mapping the brain to determine how cells communicate with each other, now she was busy mapping whether socks or shoes should go on first. Needless to say, she got an insight into neuroplasticity that few people would hope for.
What does she want us to know?
Dr. Taylor (now once again a successful scientist, lecturer, and author) advocates for “whole brain living”, which involves not taking parts of our brain for granted.
About those parts…
Dr. Taylor wants us to pay attention to all the parts regardless of size, ranging from the two hemispheres, all the way down to the billions of brain cells, and yet even further, to the “trillions of molecular geniuses”—because each brain cell is itself reliant on countless molecules of the many neurochemicals that make up our brain.
For a quick refresher on some of the key players in that latter category, see our Neurotransmitter Cheatsheet 😎
When it comes to the hemispheres, there has historically been a popular belief that these re divided into:
- The right brain: emotional, imaginative, creative, fluid feeling
- The left brain: intellectual, analytical, calculating, crystal thinking
…which is not true, anatomically speaking, because there are cells on both sides doing their part of both of these broad categories of brain processes.
However, Dr. Taylor found, while one hemisphere of her brain was much more damaged than the other, that nevertheless she could recover some functions more quickly than others, which, once she was able to resume her career, inspired her model of four distinct ways of cogitating that can be switched-between and played with or against each other:
Meet The Four Characters Inside Your Brain
Why this matters
As she was re-learning everything, the way forward was not quick or easy, and she also didn’t know where she was going, because for obvious reasons, she couldn’t remember, much less plan.
Looking backwards after her eventual full recovery, she noted a lot of things that she needed during that recovery, some of which she got and some of which she didn’t.
Most notably for her, she needed the right kind of support that would allow all four of the above “characters” as she puts it, to thrive and grow. And, when we say “grow” here we mean that literally, because of growing new brain cells to replace the lost ones (as well as the simple ongoing process of slowly replacing brain cells).
For more on growing new brain cells, by the way, see:
How To Grow New Brain Cells (At Any Age)
In order to achieve this in all of the required brain areas (i.e., and all of the required brain functions), she also wants us to know… drumroll please…
When to STFU
Specifically, the ability to silence parts of our brain that while useful in general, aren’t necessarily being useful right now. Since it’s very difficult to actively achieve a negative when it comes to brain-stuff (don’t think of an elephant), this means scheduling time for other parts of our brain to be louder. And that includes:
- scheduling time to feel (emotionally)
- scheduling time to feel (gut feelings)
- scheduling time to feel (kinesthetically)
…amongst others.
Note: those three are presented in that order, from least basic to most basic. And why? Because, clever beings that we are, we typically start from a position that’s not remotely basic, such as “overthinking”, for example. So, there’s a wind-down through thinking just the right amount, thinking through simpler concepts, feeling, noticing one’s feelings, noticing noticing one’s feelings, all the way down to what, kinesthetically, are we actually physically feeling.
❝It is interesting to note that although our limbic system fucntions throughout our lifetime, it does not mature. As a result, when our emotional “buttons” are pushed, we retain the ability to react to incoming stimulation as though we were a two-year-old, even when we are adults.❞
~ Dr. Jill Taylor
Of course, sometimes the above is not useful, which is why the ability to switch between brain modes is a very important and useful skill to develop.
And how do we do that? By practising. Which is something that it’s necessary to take up consciously, and pursue consistently. When children are at school, there are (hopefully, ideally) curricula set out to ensure they engage and train all parts of their brain. As adults, this does not tend to get the same amount of focus.
“Children’s brains are still developing”—indeed, and so are adult brains:
The Brain As A Work-In-Progress
Dr. Taylor had the uncommon experience of having to, in many ways, neurologically speaking, redo childhood. And having had a second run at it, she developed an appreciation of the process that most of us didn’t necessarily get when doing childhood just the once.
In other words: take the time to feel stuff; take the time to quiet down your chatty mind, take the time engage your senses, and take it seriously! Really notice, as though for the first time, what the texture of your carpet is like. Really notice, as though for the first time, what it feels like to swallow some water. Really notice, as though for the first time, what it feels like to experience joy—or sadness, or comfort, or anger, or peace. Exercise your imagination. Make some art (it doesn’t have to win awards; it just has to light up your brain!). Make music (again, it’s about wiring your brain in your body, not about outdoing Mozart in composition and/or performance). Make changes! Make your brain work in the ways it’s not in the habit of doing.
If you need a little help switching off parts of your brain that are being too active, so that you can better exercise other parts of your brain that might otherwise have been neglected, you might want to try:

What Omega-3 Fatty Acids Really Do For Us

What Omega-3 Fatty Acids Really Do For Us
Shockingly, we’ve not previously covered this in a main feature here at 10almonds… Mostly we tend to focus on less well-known supplements. However, in this case, the supplement may be well known, while some of its benefits, we suspect, may come as a surprise.
So…
What is it?
In this case, it’s more of a “what are they?”, because omega-3 fatty acids come in multiple forms, most notably:
- Alpha-linoleic acid (ALA)
- Eicosapentaenoic acid (EPA)
- Docosahexanoic acid (DHA)
ALA is most readily found in certain seeds and nuts (chia seeds and walnuts are top contenders), while EPA and DHA are most readily found in certain fish (hence “cod liver oil” being a commonly available supplement, though actually cod aren’t even the best source—salmon and mackerel are better; cod is just cheaper to overfish, making it the cheaper supplement to manufacture).
Which of the three is best, or do we need them all?
There are two ways of looking at this:
- ALA is sufficient alone, because it is a precursor to EPA and DHA, meaning that the body will take ALA and convert it into EPA and DHA as required
- EPA and DHA are superior because they’re already in the forms the body will use, which makes them more efficient
As with most things in health, diversity is good, so you really can’t go wrong by getting some from each source.
Unless you have an allergy to fish or nuts, in which case, definitely avoid those!
What do omega-3 fatty acids do for us, according to actual research?
Against inflammation
Most people know it’s good for joints, as this is perhaps what it’s most marketed for. Indeed, it’s good against inflammation of the joints (and elsewhere), and autoimmune diseases in general. So this means it is indeed good against common forms of arthritis, amongst others:
Read: Omega-3 fatty acids in inflammation and autoimmune disease
Against menstrual pain
Linked to the above-referenced anti-inflammatory effects, omega-3s were also found to be better than ibuprofen for the treatment of severe menstrual pain:
Don’t take our word for it: Comparison of the effect of fish oil and ibuprofen on treatment of severe pain in primary dysmenorrhea
Against cognitive decline
This one’s a heavy-hitter. It’s perhaps to be expected of something so good against inflammation (bearing in mind that, for example, a large part of Alzheimer’s is effectively a form of inflammation of the brain); as this one’s so important and such a clear benefit, here are three particularly illustrative studies:
- Inadequate supply of vitamins and DHA in the elderly: implications for brain aging and Alzheimer-type dementia
- Fish consumption and cognitive decline with age in a large community study
- Fish consumption, long-chain omega-3 fatty acids and risk of cognitive decline or Alzheimer disease
Against heart disease
The title says it all in this one:
But what about in patients who do have heart disease?
Mozaffarian and Wu did a huge meta-review of available evidence, and found that in fact, of all the studied heart-related effects, reducing mortality rate in cases of cardiovascular disease was the single most well-evidenced benefit:
How much should we take?
There’s quite a bit of science on this, and—which is unusual for something so well-studied—not a lot of consensus.
However, to summarize the position of the academy of nutrition and dietetics on dietary fatty acids for healthy adults, they recommend a minimum of 250–500 mg combined EPA and DHA each day for healthy adults. This can be obtained from about 8 ounces (230g) of fatty fish per week, for example.
If going for ALA, on the other hand, the recommendation becomes 1.1g/day for women or 1.6g/day for men.

What You Should Have Been Told About The Menopause Beforehand
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 You Should Have Been Told About Menopause Beforehand
This is Dr. Jen Gunter. She’s a gynecologist, specializing in chronic pain and vulvovaginal disorders. She’s also a woman on a mission to demystify things that popular culture, especially in the US, would rather not talk about.
When was the last time you remember the menopause being referenced in a movie or TV show? If you can think of one at all, was it just played for laughs?
And of course, the human body can be funny, so that’s not necessarily the problem, but it sure would be nice if that weren’t all that there is!
So, what does Dr. Gunter want us to know?
It’s a time of changes, not an end
The name “menopause” is misleading. It’s not a “pause”, and those menses aren’t coming back.
And yet, to call it a “menostop” would be differently misleading, because there’s a lot more going on than a simple cessation of menstruation.
Estrogen levels will drop a lot, testosterone levels may rise slightly, mood and sleep and appetite and sex drive will probably be affected (progesterone can improve all these things!) and
not to mention butwe’re going to mention: vaginal atrophy, which is very normal and very treatable with a topical estrogen cream. Untreated menopause can also bring a whole lot of increased health risks (for example, heart disease, osteoporosis, and, counterintuitively given the lower estrogen levels, breast cancer).However, with a little awareness and appropriate management, all these things can usually be navigated with minimal adverse health outcomes.
Dr Gunter, for this reason, refers to it interchangeably as “the menopausal transition”. She describes it as being less like a cliff edge we fall off, and more like a bridge we cross.
Bridges can be dangerous to cross! But they can also get us safely where we’re going.
Ok, so how do we manage those things?
Dr. Gunter is a big fan of evidence-based medicine, so we’ll not be seeing any yonic crystals or jade eggs. Or “goop”.
See also: Meet Goop’s Number One Enemy
For most people, she recommends Menopausal Hormone Therapy (MHT), which falls under the more general category of Hormone Replacement Therapy (HRT).
This is the most well-evidenced, science-based way to avoid most of the risks associated with menopause.
Nevertheless, there are scare-stories out there, ranging from painful recommencement of bleeding, to (once again) increased risk of breast cancer. However, most of these are either misunderstandings, or unrelated to menopause and MHT, and are rather signs of other problems that should not be ignored.
To get a good grounding in this, you might want to read her Hormone Therapy Guide, freely available as a standalone section on her website. This series of posts is dedicated to hormone therapy. It starts with some basics and builds on that knowledge with each post:
Dr. Gunter’s Guide To The Hormone Menoverse
What about natural therapies?
There are some non-hormonal things that work, but these are mostly things that:
- give a statistically significant reduction in symptoms
- give the same statistically significant reduction in symptoms as placebo
As Dr. Gunter puts it:
❝While most of the studies of prescription medications for hot flashes have an appropriate placebo arm, this is rarely the case with so-called alternative therapies.
In fact, the studies here are almost always low quality, so it’s often not possible to conclude much.
Many reviews that look at these studies often end with a line that goes something like, “Randomized trials with a placebo arm, a low risk of bias, and adequate sample sizes are urgently needed.”
You should interpret this kind of conclusion as the polite way of saying, “We need studies that aren’t BS to say something constructive.”❞
However, if it works, it works, whatever its mechanism. It’s just good, when making medical decisions, to do so with the full facts!
For that matter, even Dr. Gunter acknowledges that while MHT can be lifechanging (in a positive way) for many, it’s not for everyone:
Informed Decisions: When Menopause Hormone Therapy Isn’t Recommended
Want to know more?
Dr. Gunter also has an assortment of books available, including The Menopause Manifesto (which we’ve reviewed previously), and some others that we haven’t, such as “Blood” and “The Vagina Bible”.

Running: Getting Started – by Jeff Galloway
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.
Superficially, running is surely one of the easiest sports to get into, for most people. You put one foot in front of the other, repeat, and pick up the pace.
However, many people do not succeed. They head out of the door (perhaps on January the first), push themselves a little, experience runner’s high, think “this is great”, and the next day wake up with some minor aches and no motivation. This book is here to help you bypass that stage.
Jeff Galloway has quite a series of books, but the others seem derivative of this one. So, what makes this one special?
It’s quite comprehensive; it covers (as the title promises) getting started, setting yourself up for success, finding what level your ability is at safely rather than guessing and overdoing it, and building up from there.
He also talks about what kit you’ll want; this isn’t just about shoes, but even “what to wear when the weather’s not good” and so forth; he additionally shares advice about diet, exercise on non-running days, body maintenance (stretching and strengthening), troubleshooting aches and pains, and running well into one’s later years.
Bottom line: if you’d like to take up running but it seems intimidating (perhaps for reasons you can’t quite pin down), this book will take care of all those things, and indeed get you “up and running”.

You’re Not Forgetful: How To Remember Everything
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.
Elizabeth Filips, medical student busy learning a lot of information, explains how in today’s video:
Active processing
An important thing to keep in mind is that forgetting is an active process, not passive as once believed. It has its own neurotransmitters and pathways, and as such, to improve memory, it’s essential to understand and manage forgetting.
So, how does forgetting occur? Memories are stored with cues or tags, which help retrieve information. However, overloading cues with too much information can cause “transient forgetting”—that is to say, the information is still in there somewhere; you just don’t have the filing system required to retrieve the data. This is the kind of thing that you will try hard to remember at some point in the day when you need it, fail, and then wake up at 3am with an “Aha!” because your brain finally found what you were looking for. So, to avoid that, use unique and strong cues to help improve recall (mnemonics are good for this, as are conceptual anchors).
While memory does not appear to actually be finite, there is some practical truth in the “finite storage” model insofar as learning new information can overwrite previous knowledge, iff your brain mistakes it for an update rather than addition. So for that reason, it’s good to periodically go over old information—in psychology this is called rehearsal, which may conjure theatrical images, but it can be as simple as mentally repeating a phone number, a mnemonic, or visually remembering a route one used to take to go somewhere.
Self-perception affects memory performance. Negative beliefs about one’s memory can worsen performance (so don’t say “I have a bad memory”, even to yourself, and in contrast, find more positive affirmations to make about your memory), and mental health in general plays a significant role in memory. For example, if you have ever had an extended period of depression, then chances are good you have some huge gaps in your memory for that time in your life.
A lot of what we learned in school was wrong—especially what we learned about learning. Traditional (vertical) learning is harder to retain, whereas horizontal learning (connecting topics through shared characteristics) creates stronger, interconnected memories. In short, your memories should tell contextual stories, not be isolated points of data.
Embarking on a new course of study? Yes? (If not, then why not? Pick something!)
It may be difficult at first, but experts memorize things more quickly due to built-up intuition in their field. For example a chess master can glance at a chess board for about 5 seconds and memorize the position—but only if the position is one that could reasonably arise in a game; if the pieces are just placed at random, then their memorization ability plummets to that of the average person, because their expertise has been nullified.
What this means in practical terms: building a “skeleton” framework before learning can enhance memorization through logical connections. For this reason, if embarking on a serious course of study, getting a good initial overview when you start is critical, so that you have a context for the rest of what you learn to go into. For example, let’s say you want to learn a language; if you first quickly do a very basic bare-bones course, such as from Duolingo or similar, then even though you’ll have a very small vocabulary and a modest grasp of grammar and make many mistakes and have a lot of holes in your knowledge, you now have somewhere to “fit” every new word or idea you learn. Same goes for other fields of study; for example, a doctor can be told about a new drug and remember everything about it immediately, because they understand the systems it interacts with, understand how it does what it does, and can compare it mentally to similar drugs, and they thus have a “place” in that overall system for the drug information to reside. But for someone who knows nothing about medicine, it’s just a lot of big words with no meaning. So: framework first, details later.

How worried should I be about cryptosporidiosis? Am I safe at the pool?
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.
You might have heard of something called “cryptosporidiosis” recently, closely followed by warnings to stay away from your local swimming pool if you’ve had diarrhoea.
More than 700 cases of this gastrointestinal disease were reported in Queensland in January, which is 13 times more than in January last year. Just under 500 cases have been recorded in New South Wales this year to-date, while other states have similarly reported an increase in the number of cryptosporidiosis infections in recent months.
Cryptosporidiosis has been listed as a national notifiable disease in Australia since 2001.
But what exactly is it, and should we be worried?What causes cryptosporidiosis, and who is affected?
Cryptosporidiosis is the disease caused by the parasite Cryptosporidium, of which there are two types that can make us sick. Cryptosporidum hominis only affects humans and is the major cause of recent outbreaks in Australia, while Cryptosporidium parvum can also affect animals.
The infection is spread by spores called oocysts in the stools of humans and animals. When ingested, these oocysts migrate and mature in the small bowel. They damage the small bowel lining and can lead to diarrhoea, nausea, vomiting, fever and abdominal discomfort.
Most people develop symptoms anywhere from one to 12 days after becoming infected. Usually these symptoms resolve within two weeks, but the illness may last longer and can be severe in those with a weakened immune system.
Children and the elderly tend to be the most commonly affected. Cryptosporidiosis is more prevalent in young children, particularly those under five, but the disease can affect people of any age.
A number of public pools have been closed lately due to cryptosporidiosis outbreaks.
LBeddoe/ShutterstockSo how do we catch it?
Most major outbreaks of cryptosporidiosis have been due to people drinking contaminated water. The largest recorded outbreak occurred in Milwaukee in 1993 where 403,000 people were believed to have been infected.
Cryptosporidium oocysts are very small in size and in Milwaukee they passed through the filtration system of one of the water treatment plants undetected, infecting the city’s water supply. As few as ten oocysts can cause infection, making it possible for contaminated drinking water to affect a very large number of people.
Four days after infection a person with cryptosporidiosis can shed up to ten billion oocysts into their stool a day, with the shedding persisting for about two weeks. This is why one infected person in a swimming pool can infect the entire pool in a single visit.
Cryptosporidium oocysts excreted in the faeces of infected humans and animals can also reach natural bodies of water such as beaches, rivers and lakes directly through sewer pipes or indirectly such as in manure transported with surface runoff after heavy rain.
One study which modelled Cryptosporidium concentrations in rivers around the world estimated there are anywhere from 100 to one million oocysts in a litre of river water.
In Australia, cryptosporidiosis outbreaks tend to occur during the late spring and early summer periods when there’s an increase in recreational water activities such as swimming in natural water holes, water catchments and public pools. We don’t know exactly why cases have seen such a surge this summer compared to other years, but we know Cryptosporidium is very infectious.
Oocysts have been found in foods such as fresh vegetables and seafood but these are not common sources of infection in Australia.
What about chlorine?
Contrary to popular belief, chlorine doesn’t kill off all infectious microbes in a swimming pool. Cryptosporidium oocysts are hardy, thick-walled and resistant to chlorine and acid. They are not destroyed by chlorine at the normal concentrations found in swimming pools.
We also know oocysts can be significantly protected from the effects of chlorine in swimming pools by faecal material, so the presence of even small amounts of faecal matter contaminated with Cryptosporidium in a swimming pool would necessitate closure and a thorough decontamination.
Young children and in particular children in nappies are known to increase the potential for disease transmission in recreational water. Proper nappy changing, frequent bathroom breaks and showering before swimming to remove faecal residue are helpful ways to reduce the risk.
Cryptosporidium can spread in other bodies of water, not just swimming pools.
Yulia Simonova/ShutterstockSome sensible precautions
Other measures you can take to reduce yours and others’ risk of cryptosporidiosis include:
- avoid swimming in natural waters such as rivers and creeks during and for at least three days after heavy rain
- avoid swimming in beaches for at least one day after heavy rain
- avoid drinking untreated water such as water from rivers or springs. If you need to drink untreated water, boiling it first will kill the Cryptosporidium
- avoid swallowing water when swimming if you can
- if you’ve had diarrhoea, avoid swimming for at least two weeks after it has resolved
- avoid sharing towels or linen for at least two weeks after diarrhoea has resolved
- avoid sharing, touching or preparing food that other people may eat for at least 48 hours after diarrhoea has resolved
- wash your hands with soap and water after going to the bathroom or before preparing food (Cryptosporidium is not killed by alcohol gels and sanitisers).
Not all cases of diarrhoea are due to cryptosporidiosis. There are many other causes of infectious gastroenteritis and because the vast majority of the time recovery is uneventful you don’t need to see a doctor unless very unwell. If you do suspect you may have cryptosporidiosis you can ask your doctor to refer you for a stool test.

The Dirt Cure – by Dr. Maya Shetreat-Klein
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.
As we discussed in our article “Stop Sabotaging Your Gut”, there is indeed merit to living a little dirty, in particular when it comes to what we put in our mouths. Having the space of an entire book rather than a small article, Dr. Shetreat-Klein expands on this in great detail.
The subtitle mentions “growing healthy kids with food straight from the soil”; it’s worth noting that all the information here (with the exception of concerning breastfeeding etc) is equally applicable to adults too—so if it’s your own health you’re focused on rather than that of kids or grandkids, then that’s fine too.
You may be wondering: what more is there to say than “don’t scrub your vegetables as though you’re about to perform surgery with them”?
There’s a lot of background information on what things help or harm our bodies in the first place, most notably via our gut, and as an important extra consideration, the gut-brain axis. Incidentally, the author is a neurologist by professional background.
Then she gets more specific, into “include and exclude” recommendations. In this matter we have one criticism: she does recommend raw milk over pasteurized, and that is, by overwhelming scientific consensus, a terrible idea. Raw milk is an abundant source of pathogens and a breeding ground for even more. There is “living dirty” and there is “living dangerously”, and drinking raw milk is the latter. See also: Pasteurization: What It Does And Doesn’t Do
However, for the most part, the rest of her advice is sound, and there’s even a recipes section too.
The style is something of a polemic throughout, but the extensive venting does not take away from there being a lot of genuine information in here too.
Bottom line: please skip the raw milk, but aside from that, if you’d like to improve your diet to improve your gut and immune health, then this book can help with that.
