The Wandering Mind – by Dr. Michael Corballis

Our mind’s tendency to wander can be a disability, but could it also be a superpower? Dr. Corballis makes the case for such.

While many authors focus on, well, how to focus, Dr. Corballis argues in this book that our wandering imagination can be more effective at problem-solving and creative tasks, than a focused, blinkered mind.

The book’s a quick read (184 pages of quite light reading), and yet still quite dense with content. He takes us on a tour of the brain, theory of mind, the Default Mode Network (where a lot of the brain’s general ongoing organization occurs), learning, memory, forgetting, and creativity.

Furthermore, he cites (and explains) studies showing what kinds of “breaks” from mental work allow the wandering mind to do its thing at peak efficiency, and what kinds of breaks are counterproductive. Certainly this has practical applications for all of us!

Bottom line: if you’d like to be less frustrated by your mind’s tendency to wander, this is a fine book to show how to leverage that trait to your benefit.

  • A new emergency procedure for cardiac arrests aims to save more lives – here’s how it works

    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 of January this year, Aotearoa New Zealand became just the second country (after Canada) to adopt a groundbreaking new procedure for patients experiencing cardiac arrest.

    Known as “double sequential external defibrillation” (DSED), it will change initial emergency response strategies and potentially improve survival rates for some patients.

    Surviving cardiac arrest hinges crucially on effective resuscitation. When the heart is working normally, electrical pulses travel through its muscular walls creating regular, co-ordinated contractions.

    But if normal electrical rhythms are disrupted, heartbeats can become unco-ordinated and ineffective, or cease entirely, leading to cardiac arrest.

    Defibrillation is a cornerstone resuscitation method. It gives the heart a powerful electric shock to terminate the abnormal electrical activity. This allows the heart to re-establish its regular rhythm.

    Its success hinges on the underlying dysfunctional heart rhythm and the proper positioning of the defibrillation pads that deliver the shock. The new procedure will provide a second option when standard positioning is not effective.

    Using two defibrillators

    During standard defibrillation, one pad is placed on the right side of the chest just below the collarbone. A second pad is placed below the left armpit. Shocks are given every two minutes.

    Early defibrillation can dramatically improve the likelihood of surviving a cardiac arrest. However, around 20% of patients whose cardiac arrest is caused by “ventricular fibrillation” or “pulseless ventricular tachycardia” do not respond to the standard defibrillation approach. Both conditions are characterised by abnormal activity in the heart ventricles.

    DSED is a novel method that provides rapid sequential shocks to the heart using two defibrillators. The pads are attached in two different locations: one on the front and side of the chest, the other on the front and back.

    A single operator activates the defibrillators in sequence, with one hand moving from the first to the second. According to a recent randomised trial in Canada, this approach could more than double the chances of survival for patients with ventricular fibrillation or pulseless ventricular tachycardia who are not responding to standard shocks.

    The second shock is thought to improve the chances of eliminating persistent abnormal electrical activity. It delivers more total energy to the heart, travelling along a different pathway closer to the heart’s left ventricle.

    Evidence of success

    New Zealand ambulance data from 2020 to 2023 identified about 1,390 people who could potentially benefit from novel defibrillation methods. This group has a current survival rate of only 14%.

    Recognising the potential for DSED to dramatically improve survival for these patients, the National Ambulance Sector Clinical Working Group updated the clinical procedures and guidelines for emergency medical services personnel.

    The guidelines now specify that if ventricular fibrillation or pulseless ventricular tachycardia persist after two shocks with standard defibrillation, the DSED method should be administered. Two defibrillators need to be available, and staff must be trained in the new approach.

    Though the existing evidence for DSED is compelling, until recently it was based on theory and a small number of potentially biased observational studies. The Canadian trial was the first to directly compare DSED to standard treatment.

    From a total of 261 patients, 30.4% treated with this strategy survived, compared to 13.3% when standard resuscitation protocols were followed.

    The design of the trial minimised the risk of other factors confounding results. It provides confidence that survival improvements were due to the defibrillation approach and not regional differences in resources and training.

    The study also corroborates and builds on existing theoretical and clinical scientific evidence. As the trial was stopped early due to the COVID-19 pandemic, however, the researchers could recruit fewer than half of the numbers planned for the study.

    Despite these and other limitations, the international group of experts that advises on best practice for resuscitation updated its recommendations in 2023 in response to the trial results. It suggested (with caution) that emergency medical services consider DSED for patients with ventricular fibrillation or pulseless ventricular tachycardia who are not responding to standard treatment.

    Training and implementation

    Although the evidence is still emerging, implementation of DSED by emergency services in New Zealand has implications beyond the care of patients nationally. It is also a key step in advancing knowledge about optimal resuscitation strategies globally.

    There are always concerns when translating an intervention from a controlled research environment to the relative disorder of the real world. But the balance of evidence was carefully considered before making the decision to change procedures for a group of patients who have a low likelihood of survival with current treatment.

    Before using DSED, emergency medical personnel undergo mandatory education, simulation and training. Implementation is closely monitored to determine its impact.

    Hospitals and emergency departments have been informed of the protocol changes and been given opportunities to ask questions and give feedback. As part of the implementation, the St John ambulance service will perform case reviews in addition to wider monitoring to ensure patient safety is prioritised.

    Ultimately, those involved are optimistic this change to cardiac arrest management in New Zealand will have a positive impact on survival for affected patients.The Conversation

  • What Curiosity Really Kills

    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.

    Curiosity Kills The Neurodegeneration

    Of the seven things that Leonardo da Vinci considered most important for developing and maintaining the mind, number one on his list was curiosity, and we’re going to be focussing on that today.

    In case you are curious about what seven things made Leonardo’s* list, they were:

    1. Curiosità: an insatiably curious approach to life and an unrelenting quest for continuous learning
    2. Dimostrazione: a commitment to test knowledge through experience, persistence, and a willingness to learn from mistakes
    3. Sensazione: the continual refinement of the senses, especially sight, as a means to enliven experience
    4. Sfumato: (lit: “gone up in smoke”) a willingness to embrace ambiguity, paradox, and uncertainty
    5. Arte/Scienza: the curated balance of art and science, imagination and logic
    6. Corporalità: the cultivation of physical grace, ambidexterity, and fitness
    7. Connessione: a recognition of and appreciation for the interconnectedness of phenomena (systems-based thinking)

    *In case you are curious why we wrote “Leonardo” and not “da Vinci” as per our usual convention of shortening names to last names, da Vinci is not technically a name, in much the same way as “of Nazareth” was not a name.

    You can read more about all 7 of these in a book that we’ve reviewed previously:

    How to Think Like Leonardo da Vinci: Seven Steps to Genius Every Day – by Michael J. Gelb

    But for now, let’s take on “curiosity”!

    If you need an extra reason to focus on growing and nurturing your curiosity, it was also #1 of Dr. Daniel Levitin’s list of…

    The Five Keys Of Aging Healthily

    …and that’s from a modern-day neuroscientist whose research focuses on aging, the brain, health, productivity, and creativity.

    But how do we foster curiosity in the age of Google?

    Curiosity is like a muscle: use it or lose it

    While it’s true that many things can be Googled to satisfy one’s curiosity in an instant…

    • do you? It’s only useful if you do use it
    • is the top result on Google reliable?
    • there are many things that aren’t available there

    In short: douse “fast food information” sources, but don’t rely on them! Not just for the sake of having correct information, but also: for the actual brain benefits which is what we are aiming for here with today’s article.

    If you want the best brain benefits, dive in, and go deep

    Here at 10almonds we often present superficial information, with links to deeper information (often: scholarly articles). We do this because a) there’s only so much we can fit in our articles and b) we know you only have so much time available, and/but may choose to dive deeper.

    Think of it in layers, e.g:

    • Collagen is good for joints and bones
    • Collagen is a protein made of these amino acids that also requires these vitamins and minerals to be present in order to formulate it
    • Those amino acids are needed in these quantities, of which this particular one is usually the weakest link that might need supplementing, and those vitamins and minerals need to be within this period of time, but not these ones at the exact same time, or else it will disrupt the process of collagen synthesis

    (in case you’re curious, we covered this here and here and offered a very good, very in-depth book about it here)

    Now, this doesn’t mean that to have a healthy brain you need to have the equivalent knowledge of an anatomy & physiology degree, but it is good to have that level of curiosity in at least some areas of your life—and the more, the better.

    Top tips for developing a habit of curiosity

    As you probably know, most of our endeavors as humans go best when they are habits:

    How To Really Pick Up (And Keep!) Those Habits

    And as for specifically building a habit of curiosity:

    1. Make a deal with yourself that when someone is excited to tell you what they know about something (no matter whether it is your grandkid, or the socially awkward nerd at a party, or whoever), listen and learn, no matter the topic.
    2. Learn at least one language other than your native language (presumably English for most of our readers). Not only does learning a language convey a lot of brain benefits of its own, but also, it is almost impossible to separate language learning from cultural learning, and so you will learn a lot about another culture too, and have whole new worlds opened up to you. Again, more is better, but one second language is already a lot better than none.
    3. Make a regular habit of going to your local library, and picking out a non-fiction book to take home and read. This has an advantage over a bookshop, by the way (and not just that the library is free): since library books must be returned, you will keep going back, and build a habit of taking out books.
    4. Pick a skill that you’d like to make into a fully-fledged hobby, and commit to continually learning as much about it as you can. We already covered language-learning above, but others might include: gardening (perhaps a specific kind), cooking (perhaps a specific kind), needlecraft (perhaps a specific kind), dance (perhaps a specific kind). You could learn a musical instrument. Or it could be something very directly useful, like learning to be a first responder in case of emergencies, and committing to continually learning more about it (because there is always more to learn).

    And when it comes to the above choices… Pick things that excite you, regardless of how practical or not they are. Because that stimulation that keeps on driving you? That’s what keeps your brain active, healthy, and sharp.

    Enjoy!

  • Your Health Audit, From Head To Toe

    Health Audit Time

    Here at 10almonds, we often cover quite specific things, ranging from “the effect of sodium on organs other than your heart” to “make this one small change to save your knees while driving”.

    But, we’re each a whole person, and we need to take care of the whole organism that makes up the wonderful being that we each are. If we let one part of it drop in health too much, the others will soon follow suit because of the knock-on effects.

    So, let’s do a quick self-check-up, and see what can be done for each! How’s your…

    Mental Health

    We’re doing this audit head-to-to, so let’s start it here, because mental health is also just health, and it’s difficult to tackle the others without having this one at least under control!

    Are you experiencing chronic stress? Anxiety? Depression? Joy?

    If you answered “no” to “joy” but also “no” to “depression”, you might want to rethink your answer to “depression”, by the way. Life should be a joyous thing!

    Some resources to address your mental health:

    Brain Health

    Your brain is a big, powerful organ. It uses more of your daily energy (in the physiological sense of the word, we’re talking calories and mitochondria and ATP) than any other organ, by far.

    And when it comes to organ failure, if your brain fails, then having the best joints in the world won’t help you, for example.

    Some resources to address your brain health:

    Heart Health

    Everything depends on your heart, head to toe. Tirelessly pumping blood with oxygen, nutrients, and agents of your immune system all around your body, all day every day for your entire life.

    What’s your resting heart rate like? How about your blood pressure? And while we’re on the topic of blood… how’s your blood sugar health?

    These are all important things to a) know about and b) keep on top of!

    Some resources to address your heart health:

    Gut Health

    By cell count, we’re about 10% human and 90% bacteria. By gene count, also. Pretty important, therefore, that we look after our trillions of tiny friends that keep our organism working.

    Most people in N. America, for example, get vastly under the recommended daily amount of fiber, and that’s just the most basic courtesy we could do for these bugs that keep us alive (they need that fiber to live, and their process of consuming it is beneficial to us in a stack of ways).

    Some resources to address your gut health:

    Hormonal Health

    Hormones are weird and wonderful and affect so much more than the obvious sex-related functions (but yes, those too). A lot of people don’t realize it, but having our hormones in good order or not can make the difference between abject misery and a happy, fulfilling life.

    Some resources to address your hormonal health:

    Bone/Joint Health

    Fear nothing! For you are a ghost operating a skeleton clad in flesh. But also, you know, look after that skeleton; you only get one! Being animals, we’re all about movement, and being humans, we’ve ended up with some lifestyle situations that aren’t great for that mobility. We sit too much; we walk too little; we cramp ourselves into weird positions (driving, anyone?), and we forget the range of motion we’re supposed to have. But let’s remember…

    Some resources to address your bone/joint health:

    Lastly…

    While it’s good to do a little self-audit like this every now and again, it’s even better to get a professional check-up!

    As engineers say: if you don’t schedule time for maintenance, your equipment will schedule it for you.

    It’s that time of the year, and many of us hope to make this our healthiest year yet—or at least significantly improve it in some particular area that’s important to us! So, what news from the health world?

    The rise of GLP-1 agonists continues

    GLP-1 agonists have surged in popularity in the past year, and it looks like that trend is set to continue in the new one. The title of the below-linked pop-science article is slightly misleading, it’s not “almost three quarters of UK women”, but rather, “72% of the women using the digital weight loss platform Juniper”, which means the sample is confined to people interested in weight loss. Still, of those interested in weight loss, 72% is a lot, and the sample size was over 1000:

    The lesser of two evils

    Smoking is terrible, for everything. Vaping is… Not great, honestly, but as the below-discussed study shows, at the very least it results in much less severe respiratory symptoms than actual smoking. For many, vaping is a halfway-house to actually quitting; for some, it’s just harm reduction, and that too can be worthwhile.

    We imagine that probably very few 10almonds readers smoke cigarettes, but we know quite a few use cannabis, which is discussed also:

    Sometimes, more is more

    The below-linked pop-science article has a potentially confusingly-worded title that makes it sound like increased exercise duration results in decreasing marginal returns (i.e., after a certain point, you’re getting very limited extra benefits), but in fact the study says the opposite.

    Rather, increased moderate exercise (so, walking etc) results in a commensurately decreasing weight and a decreasing waistline.

    In short: walk more, lose more (pounds and inches). The study examined those who moved their bodies for 150–300 minutes per week:

  • Dates vs Prunes – 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 dates to prunes, we picked the prunes.

    Why?

    First let’s note: we’re listing the second fruit here as “prunes” rather than “plums”, since prunes are dehydrated plums, and it makes more sense to compare the dried fruit to dates which are invariably dried too. Otherwise, the water weight of plums would unfairly throw out the nutrient proportions per 100g (indeed, upon looking up numbers, dates would overwhelmingly beat plums easily in the category of pretty much every nutrient).

    So let’s look at the fairer comparison:

    In terms of macros, dates have a little more protein, carbohydrate, and fiber. This is because while both are dried, prunes are usually sold with more water remaining than dates; indeed, per 100g prunes still have 30g water weight to dates’ 20g water weight. This makes everything close, but we are going to call this category a nominal win for dates. Mind you, hydration is still good, but please do not rely on dried fruit for your hydration!

    When it comes to vitamins, dates have more of vitamins B5 and B9, while prunes have more of vitamins A, B2, B3, B6, C, E, K, and choline. A clear win for prunes here.

    In the category of minerals, it’s a similar story: dates have more iron, magnesium, and selenium, while prunes have more calcium, copper, manganese, phosphorus, potassium, and zinc. Another win for prunes.

    In short, enjoy either or both, but prunes win on overall nutritional density!

  • How can I stop overthinking everything? A clinical psychologist offers solutions

    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 a clinical psychologist, I often have clients say they are having trouble with thoughts “on a loop” in their head, which they find difficult to manage.

    While rumination and overthinking are often considered the same thing, they are slightly different (though linked). Rumination is having thoughts on repeat in our minds. This can lead to overthinking – analysing those thoughts without finding solutions or solving the problem.

    It’s like a vinyl record playing the same part of the song over and over. With a record, this is usually because of a scratch. Why we overthink is a little more complicated.

    We’re on the lookout for threats

    Our brains are hardwired to look for threats, to make a plan to address those threats and keep us safe. Those perceived threats may be based on past experiences, or may be the “what ifs” we imagine could happen in the future.

    Our “what ifs” are usually negative outcomes. These are what we call “hot thoughts” – they bring up a lot of emotion (particularly sadness, worry or anger), which means we can easily get stuck on those thoughts and keep going over them.

    However, because they are about things that have either already happened or might happen in the future (but are not happening now), we cannot fix the problem, so we keep going over the same thoughts.

    Who overthinks?

    Most people find themselves in situations at one time or another when they overthink.

    Some people are more likely to ruminate. People who have had prior challenges or experienced trauma may have come to expect threats and look for them more than people who have not had adversities.

    Deep thinkers, people who are prone to anxiety or low mood, and those who are sensitive or feel emotions deeply are also more likely to ruminate and overthink.

    We all overthink from time to time, but some people are more prone to rumination.
    BĀBI/Unsplash

    Also, when we are stressed, our emotions tend to be stronger and last longer, and our thoughts can be less accurate, which means we can get stuck on thoughts more than we would usually.

    Being run down or physically unwell can also mean our thoughts are harder to tackle and manage.

    Acknowledge your feelings

    When thoughts go on repeat, it is helpful to use both emotion-focused and problem-focused strategies.

    Being emotion-focused means figuring out how we feel about something and addressing those feelings. For example, we might feel regret, anger or sadness about something that has happened, or worry about something that might happen.

    Acknowledging those emotions, using self-care techniques and accessing social support to talk about and manage your feelings will be helpful.

    The second part is being problem-focused. Looking at what you would do differently (if the thoughts are about something from your past) and making a plan for dealing with future possibilities your thoughts are raising.

    But it is difficult to plan for all eventualities, so this strategy has limited usefulness.

    What is more helpful is to make a plan for one or two of the more likely possibilities and accept there may be things that happen you haven’t thought of.

    Think about why these thoughts are showing up

    Our feelings and experiences are information; it is important to ask what this information is telling you and why these thoughts are showing up now.

    For example, university has just started again. Parents of high school leavers might be lying awake at night (which is when rumination and overthinking is common) worrying about their young person.

    Think of what the information is telling you.
    TheVisualsYouNeed/Shutterstock

    Knowing how you would respond to some more likely possibilities (such as they will need money, they might be lonely or homesick) might be helpful.

    But overthinking is also a sign of a new stage in both your lives, and needing to accept less control over your child’s choices and lives, while wanting the best for them. Recognising this means you can also talk about those feelings with others.

    Let the thoughts go

    A useful way to manage rumination or overthinking is “change, accept, and let go”.

    Challenge and change aspects of your thoughts where you can. For example, the chance that your young person will run out of money and have no food and starve (overthinking tends to lead to your brain coming up with catastrophic outcomes!) is not likely.

    You could plan to check in with your child regularly about how they are coping financially and encourage them to access budgeting support from university services.

    Your thoughts are just ideas. They are not necessarily true or accurate, but when we overthink and have them on repeat, they can start to feel true because they become familiar. Coming up with a more realistic thought can help stop the loop of the unhelpful thought.

    Accepting your emotions and finding ways to manage those (good self-care, social support, communication with those close to you) will also be helpful. As will accepting that life inevitably involves a lack of complete control over outcomes and possibilities life may throw at us. What we do have control over is our reactions and behaviours.

    Remember, you have a 100% success rate of getting through challenges up until this point. You might have wanted to do things differently (and can plan to do that) but nevertheless, you coped and got through.

    So, the last part is letting go of the need to know exactly how things will turn out, and believing in your ability (and sometimes others’) to cope.

    What else can you do?

    A stressed out and tired brain will be more likely to overthink, leading to more stress and creating a cycle that can affect your wellbeing.

    So it’s important to manage your stress levels by eating and sleeping well, moving your body, doing things you enjoy, seeing people you care about, and doing things that fuel your soul and spirit.

    Distraction – with pleasurable activities and people who bring you joy – can also get your thoughts off repeat.

    If you do find overthinking is affecting your life, and your levels of anxiety are rising or your mood is dropping (your sleep, appetite and enjoyment of life and people is being negatively affected), it might be time to talk to someone and get some strategies to manage.

    When things become too difficult to manage yourself (or with the help of those close to you), a therapist can provide tools that have been proven to be helpful. Some helpful tools to manage worry and your thoughts can also be found here.

    When you find yourself overthinking, think about why you are having “hot thoughts”, acknowledge your feelings and do some future-focused problem solving. But also accept life can be unpredictable and focus on having faith in your ability to cope. The Conversation
