How To Stop Revisiting Those Memories
We’ve talked before about putting the brakes on negative thought spirals (and that’s a really useful technique, so if you weren’t with us yet for that one, we do recommend hopping back and reading it!).
We’ve also talked about optimizing memory, to include making moments unforgettable.
But what about the moments we’d rather forget?
First, a quick note: we have no pressing wish or need to re-traumatize any readers, so if you’ve a pressing reason to think your memories you’d rather forget are beyond the scope of a few hundred words “one quick trick” in a newsletter, feel free to skip this section today.
One more quick note: it is generally not considered healthy to repress important memories. Some things are best worked through consciously in therapy with a competent professional.
Today’s technique is more for things in the category of “do you really need to keep remembering that one time you did something embarrassing 20 years ago?”
That said… sometimes, even when it does come to the management of serious PTSD, therapy can (intentionally, reasonably) throw in the towel on processing all of something big, and instead seek to simply look at minimizing its effect on ongoing life. Again, that’s best undertaken with a well-trained professional, however.
For more trivial annoyances, meanwhile…
Two Steps To Forgetting
The first step:
You may remember that memories are tied to the senses, and the more senses are involved, the more easily and fully we remember a thing. To remember something, therefore, we make sure to pay full attention to all the sensory experience of the memory, bringing in all 5 senses if possible.
To forget, the reverse is true. Drain the memory of color, make it black and white, fuzzier, blurrier, smaller, further away, sterile, silent, gone.
You can make a habit of doing this automatically whenever your unwanted memory resurfaces.
The second missing step:
This is the second step, but it’s going to be a missing step. Memories, like paths in a forest, are easier to access the more often we access them. A memory we visit every day will have a well-worn path, easy to follow. A memory we haven’t visited for decades will have an overgrown, sometimes nearly impossible-to-find path.
To labor the metaphor a little: if your memory has literal steps leading to it, we’re going to remove one of the steps now, to make it very difficult to access accidentally. Don’t worry, you can always put the step back later if you want to.
Let’s say you want to forget something that happened once upon a time in a certain workplace. Rather than wait for the memory in question to come up, we’re going to apply the first step that we just learned, to the entire workplace.
So, in this example, you’d make the memory of that workplace drained of color, made black and white, fuzzier, blurrier, smaller, further away, sterile, silent, gone.
Then, you’d make a habit of doing that whenever that workplace nearly comes to mind.
The result? You’re unlikely to accidentally access a memory that occurred in that workplace, if even mentally wandering to the workplace itself causes it to shrivel up and disappear like paper in fire.
Important reminder
The above psychological technique is to psychological trauma what painkillers are to physical pain. It can ease the symptom, while masking the cause. If it’s something serious, we recommend enlisting the help of a professional, rather than “self-medicating” in this fashion.
If it’s just a small annoying thing, though, sometimes it’s easier to just be able to refrain from prodding and poking it daily, forget about it, and enjoy life.

The Glucose Goddess Method – by Jessie Inchausspé
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 previously reviewed Inchausspé’s excellent book “Glucose Revolution”. So what does this book add?
This book is for those who found that book a little dense. While this one still gives the same ten “hacks”, she focuses on the four that have the biggest effect, and walks the reader by the hand through a four-week programme of implementing them.
The claim of 100+ recipes is a little bold, as some of the recipes are things like vinegar, vinegar+water, vinegar+water but now we’re it’s in a restaurant, lemon+water, lemon+water but now it’s in a bottle, etc. However, there are legitimately a lot of actual recipes too.
Where this book’s greatest strength lies is in making everything super easy, and motivating. It’s a fine choice for being up-and-running quickly and easily without wading through the 300-odd pages of science in her previous book.
Bottom line: if you’ve already happily and sustainably implemented everything from her previous book, you can probably skip this one. However, if you’d like an easier method to implement the changes that have the biggest effect, then this is the book for you.

Celery vs Parsley – 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 celery to parsley, we picked the parsley.
Why?
Firstly, you may be thinking: “What kind of a comparison is this?! Parsley is a seasoning or a garnish; who uses it as a salad option option?!” and the answer is that nobody can stop you from using herbs as a main greenery option, and in fact, we recommend it (both for adding a lot of flavor to your plate, and getting in a lot of nutrients).
So, with that in mind, let’s get to it:
In terms of macros, parsley has 2x the fiber for 2x the carbs and 5x the protein, winning in this category easily.
In the category of vitamins, celery is not higher in any vitamins, while parsley has a lot more of vitamins A, B1, B2, B3, B5, B6, B7, B9, C, E, and K, sweeping its second round completely.
Looking at minerals, celery does have more selenium, while parsley has a lot more calcium, copper, iron, magnesium, manganese, phosphorus, potassium, and zinc, convincingly winning its third round in a row.
In other considerations, they both are great sources of polyphenols, though celery (albeit notably the leaves thereof, not the stalks so much) does have more flavonoids specifically, and may arguably pick up a point here.
Adding up the sections makes for a clear overall win for parsley, but by all means do enjoy either or both, as diversity is best!
(Unless you are allergic to celery, in which case, definitely do stick the parsley!)

When supplies resume, should governments subsidise drugs like Ozempic for weight loss? We asked 5 experts
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.
Hundreds of thousands of people worldwide are taking drugs like Ozempic to lose weight. But what do we actually know about them? This month, The Conversation’s experts explore their rise, impact and potential consequences.
You’ve no doubt heard of Ozempic but have you heard of Wegovy? They’re both brand names of the drug semaglutide, which is currently in short supply worldwide.
Ozempic is a lower dose of semaglutide, and is approved and used to treat diabetes in Australia. Wegovovy is approved to treat obesity but is not yet available in Australia. Shortages of both drugs are expected to last throughout 2024.
Both drugs are expensive. But Ozempic is listed on Australia’s Pharmaceutical Benefits Schedule (PBS), so people with diabetes can get a three-week supply for A$31.60 ($7.70 for concession card holders) rather than the full price ($133.80).
Wegovy isn’t listed on the PBS to treat obesity, meaning when it becomes available, users will need to pay the full price. But should the government subsidise it?
Wegovy’s manufacturer will need to make the case for it to be added to the PBS to an independent advisory committee. The company will need to show Wegovy is a safe, clinically effective and cost-effective treatment for obesity compared to existing alternatives.
In the meantime, we asked five experts: when supplies resume, should governments subsidise drugs like Ozempic for weight loss?
Four out of five said yes
This is the last article in The Conversation’s Ozempic series. Read the other articles here.

Does Your Hair Ever Stop Growing?
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.
…and how long can it grow?
Staying ahead
Because scalp hair usually stops growing after 5–7 years and then sheds, the average maximum length is about 75–105cm, though genetics, hormones, and health can extend or shorten this.
But that’s scalp hair; scalp follicles typically grow hair for 5–7 years at roughly 15cm per year, while eyelash follicles have a much shorter growth phase, limiting lashes to around 1cm.
You may be wondering why different body hair behaves differently: fibroblasts in each follicle determine whether hair becomes scalp hair, eyelashes, or other body hair, controlling growth rate, thickness, shape, and color based on location.
In the case of current world record-holder Xie Quiping, her record-breaking hair length over 5 meters resulted from an unusually long anagen (growth) phase, combined with helpful genetics, good health, and minimal breakage.
As for things that can get in the way:
- Why baldness happens: follicles can shrink and eventually stop producing hair when epithelial stem cells decline, while testosterone-related effects can also interfere with growth signals.
- Why hair turns gray: follicles gradually lose melanocyte stem cells, reducing pigment production and leading to gray or white hair, which in turn is usually more brittle, thus breaks more easily, thus does not usually reach the same lengths as pre-gray hair.
As for whether we can speed up hair growth: technically no, as no known treatment can make hair exceed its biological growth speed. But! Some treatments can reduce hair loss or improve hair condition, which will result in the appearance of quicker-growing hair, since the overall length will increase (due to reduced breakage and reduced shedding).

The Cough Doctor
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 Cough Doctor
This is Dr. Peter Small, who worked in epidemiology since the beginning of HIV epidemic. He became a pioneer in the field of molecular epidemiology. As such, his work was a guiding beacon for the public health response to the resurgence of tuberculosis. He’s travelled the world spending years in various institutions studying all manner of respiratory illnesses…. These have ranged from tuberculosis to pneumonia to lung cancer and (back to epidemiology) Covid-19.
He’s now the Chief Medical Officer at…
Hyfe
Hyfe, a medical AI company, was founded in 2020. Its objective: to build acoustic tools for respiratory diagnostics and monitoring.
In other words: it records coughs and collects data about coughing.
❝It’s ironic how much people focus on counting steps while ignoring cough, which is far more consequential. Hyfe is a science-driven company with the technology to make cough count. Particularly now, with increased awareness of cough and the rapid growth of digital health driven by Covid-19, this technology can improve the lives of patients, the care provided by doctors, and the efficiency of health systems.❞
~ Dr. Peter Small, CMO, Hyfe
How does it do it?
Hyfe’s AI monitors the number of times a person coughs and the sound of the cough through any smartphone or other smart device.
This data collected over time provides increasingly more reliable information than a single visit to the doctor! By constantly listening and analyzing, it can detect patterns that might otherwise go unnoticed.
How big is this “big data” effort?
Hyfe maintains the largest cough dataset in the world. This means it can compare the sound of a patient’s cough with more than 400 million cough-like sounds from 83 countries across all continents.
The human brain doesn’t handle big numbers well. So, just to illustrate: if the average cough is 1 second long, that means it’d take more than 12 years to listen to them all.
Hyfe, meanwhile, can:
- listen to many things simultaneously
- index them all against user and location,
- use its ever-growing neural net to detect and illustrate patterns.
It’s so attentive, that it can learn to distinguish between different people’s coughs in the same household.
❝Companies like Google Health see even basic information such as getting an accurate count of the number of times a person coughs a day as a useful resource, and part of a larger need to collect and chronicle more health information to refine the way doctors diagnose disease and manage treatments in the future.❞
What are the public health implications?
The most obvious application is to note when there’s a spike in coughing, and see how such spikes grow and spread (if they do), to inform of contagion risks.
Another is to cross-reference it with data about local environmental allergens. Knowing how things like pollution and even pollen affect individuals differently could be helpful in identifying (and managing) chronic conditions like asthma.
What are the private health implications?
❝It’s going to transform the whole clinical approach for this common and chronic symptom. Patients will come in, have the data on how much they are coughing, and the physician can suggest a treatment based on that information to see if it makes the coughs better❞
~ Dr. Peter Small
Dr. Small’s colleague Dr. Cai, speaking for Google Health on this project, sees even more utility for diagnostics:
❝When I was in medical school, never ever did they teach us that we could listen to somebody cough and identify whether that person has TB (tuberculosis), COPD, or a tumor. But I keep seeing more and more studies of people coughing into a microphone, and an algorithm can detect whether somebody has TB with 95% specificity and sensitivity, or if someone has pneumonia or an exacerbation of COPD❞
~ Dr. Lawrence Cai
And the privacy implications?
Perhaps you don’t quite fancy the idea of not being able to cough without Google knowing about it. Hyfe’s software is currently opt-in, but…
If you cough near someone else’s Hyfe app, their app will recognize you’re not the app’s user, and start building a profile for you. Of course, that won’t be linked to your name, email address, or other IDs, as it would if you were the app’s user.
Hyfe will ask to connect to your social media, to collect more information about you and your friends.

How To Reduce Chronic Stress
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.
Sunday Stress-Buster
First, an important distinction:
- Acute stress (for example, when stepping out of your comfort zone, engaging in competition, or otherwise focusing on something that requires your full attention for best performance) is generally a good thing. It helps you do you your best. It’s sometimes been called “eustress”, “good stress”.
- Chronic stress (for example, when snowed under at work and you do not love it, when dealing with a serious illness, and/or faced with financial problems) is unequivocally a bad thing. Our body is simply not made to handle that much cortisol (the stress hormone) all the time.
Know the dangers of too much cortisol
We covered this as a main feature last month: Lower Your Cortisol! (Here’s Why & How)
…but it bears mentioning again and for those who’ve joined us since then:
A little spike of cortisol now and again can be helpful. Having it spiking all the time, or even a perpetual background low-to-moderate level, can be ruinous to the health in so many ways.
The good news is, the physiological impact of stress on the body (which ranges from face-and-stomach fat deposits, to rapid aging), can be reversed—even the biological aging!
Read: Biological age is increased by stress and restored upon recovery ← this study is so hot-of-the-press that it was published literally two days ago
Focus on what you can control
A lot of things that cause you stress may be outside of your control. Focus on what is within your control. Oftentimes, we are so preoccupied with the stress, that we employ coping strategies that don’t actually deal with the problem.
That’s a maladaptive response to an evolutionary quirk—our bodies haven’t caught up with modern life, and on an evolutionary scale, are still priming us to deal with sabre-toothed tigers, not financial disputes, for example.
But, how to deal with the body’s “wrong” response?
First, deal with the tiger. There isn’t one, but your body doesn’t know that. Do some vigorous exercise, or if that’s not your thing, tense up your muscles strongly for a few seconds and then relax them, doing each part of your body. This is called progressive relaxation, and how it works is basically tricking your body into thinking you successfully fled the tiger, or fought the tiger and won.
Next, examine what the actual problem is, that’s causing you stress. You’re probably heavily emotionally attached to the problem, or else it wouldn’t be stressing you. So, imagine what advice you would give to help a friend deal with the same problem, and then do that.
Better yet: enlist an actual friend (or partner, family member, etc) to help you. We are evolved to live in a community, engaged in mutual support. That’s how we do well; that’s how we thrive best.
By dealing with the problem—or sometimes even just having support and/or something like a plan—your stress will evaporate soon enough.
The power of “…and then what?”
Sometimes, things are entirely out of your control. Sometimes, bad things are entirely possible; perhaps even probable. Sometimes, they’re so bad, that it’s difficult to avoid stressing about the possible outcomes.
If something seems entirely out of your control and/or inevitable, ask yourself:
“…and then what?”
- What if this is cancer? Well, it might be. And then what? You might seek cancer treatment.
- What if I can’t get treatment, or it doesn’t work? Well, you might die. And then what?
In Dialectic Behavior Therapy (DBT), this is called “radical acceptance” and acknowledges bad possible/probable/known outcomes, allows one to explore the feelings, and come up with a plan for managing the situation, or even just coming to terms with the fact that sometimes, suffering is inevitable and is part of the human condition.
It’ll still be bad—but you won’t have added extra suffering in the form of stress.
Breathe.
Don’t underestimate the power of relaxed deep breathing to calm the rest of your body, including your brain.
Also: we’ve shared this before, a few months ago, but this 8 minute soundscape was developed by sound technicians working with a team of psychologists and neurologists. It’s been clinically tested, and found to have a much more relaxing effect(in objective measures of lowering heart rate and lowering cortisol levels, as well as in subjective self-reports) than merely “relaxing music”.
Try it and see for yourself:
