11 Things That Can Change Your Eye Color

Eye color is generally considered so static that iris scans are considered a reasonable security method. However, it can indeed change—mostly for reasons you won’t want, though:
Ringing the changes
Putting aside any wishes of being a manga protagonist with violet eyes, here are the self-changing options:
- Aging in babies: babies are often born with lighter eyes, which can darken as melanocytes develop during the first few months of life. This is similar to how a small child’s blonde hair can often be much darker by the time puberty hits!
- Aging in adults: eyes may continue to darken until adulthood, while aging into the elderly years can cause them to lighten due to conditions like arcus senilis
- Horner’s syndrome: a nerve disorder that can cause the eyes to become lighter due to loss of pigment
- Fuchs heterochromic iridocyclitis: an inflammation of the iris that leads to lighter eyes over time
- Pigment dispersion syndrome: the iris rubs against eye fibers, leading to pigment loss and lighter eyes
- Kayser-Fleischer rings: excess copper deposits on the cornea, often due to Wilson’s disease, causing larger-than-usual brown or grayish rings around the iris
- Iris melanoma: a rare cancer that can darken the iris, often presenting as brown spots
- Cancer treatments: chemotherapy for retinoblastoma in children can result in lighter eye color and heterochromia
- Medications: prostaglandin-based glaucoma treatments can darken the iris, with up to 23% of patients seeing this effect
- Vitiligo: an autoimmune disorder that destroys melanocytes, mostly noticed in the skin, but also causing patchy loss of pigment in the iris
- Emotional and pupil size changes: emotions and trauma can affect pupil size, making eyes appear darker or lighter temporarily by altering how much of the iris is visible

Kettlebell Swings Are Not What Most People Think They Are (They’re Better)
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.
Commonly assumed to be mostly a shoulders-and-arms exercise, they’re actually mostly about the hips and core:
From the hips
Correctly executed kettlebell swings primarily strengthens muscles from the hamstrings and glutes the to abs and back; in other words, muscles whose strength is essential for power, posture, and injury prevention.
The core in particular is not to be underestimated, with deep stabilizing muscles supporting posture, balance, and movement. Strengthening these areas can also help reduce lower back pain.
How to do it correctly: start with your feet shoulder-width apart (this is important, if you like having knees) and grip the kettlebell with both hands. Hinge at your hips, lowering the kettlebell between your legs while keeping your back flat and core engaged. Then, drive your hips forward explosively to swing the kettlebell up to shoulder height before allowing it to return down with control. The most common mistake is using the arms to lift the kettlebell, but the real power should come from the hips to maximize benefits and prevent injury.
Example workout: 30 seconds of kettlebell swings followed by 30 seconds of rest, repeated for 10 sets. This 10-minute routine provides a full-body workout that builds strength and endurance. As you progress, you can increase the weight, duration, number of sets, etc.
Timeline of changes: within a few weeks of regular kettlebell swings, you should notice stronger glutes, better endurance, and improved posture. After a month, you may experience reduced lower back pain (if you had lower back pain) and more power in your everyday movements. By two to three months, visible muscle definition and fat loss are likely to become noticeable, along with increased overall strength.

Your Brain on Art – by Susan Magsamen & Ivy Ross

The notion of art therapy is popularly considered a little wishy-washy. As it turns out, however, there are thousands of studies showing its effectiveness.
Nor is this just a matter of self-expression. As authors Magsamen and Ross explore, different kinds of engagement with art can convey different benefits.
That’s one of the greatest strengths of this book: “this form of engagement with art will give these benefits, according to these studies”
With benefits ranging from reducing stress and anxiety, to overcoming psychological trauma or physical pain, there’s a lot to be said for art!
And because the book covers many kinds of art, if you can’t imagine yourself taking paintbrush to canvas, that’s fine too. We learn of the very specific cognitive benefits of coloring in mandalas (yes, really), of sculpting something terrible in clay, or even just of repainting the kitchen, and more. Each thing has its set of benefits.
The book’s main goal is to encourage the reader to cultivate what the authors call an aesthetic mindset, which involves four key attributes:
- a high level of curiosity
- a love of playful, open-ended exploration
- a keen sensory awareness
- a drive to engage in creative activities
And, that latter? It’s as a maker and/or a beholder. We learn about what we can gain just by engaging with art that someone else made, too.
Bottom line: come for the evidence-based cognitive benefits; stay for the childlike wonder of the universe. If you already love art, or have thought it’s just “not for you”, then this book is for you.

Daily Activity Levels & The Measurable Difference They Make To Brain Health
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.
Most studies into the difference that exercise makes to cognitive decline are retrospective, i.e. they look backwards in time, asking participants what their exercise habits were like in the past [so many] years, and tallying that against their cognitive health in the present.
Some studies are interventional, and those are most often 3, 6, or 12 months, depending on funding. In those cases, they make a hypothesis (e.g. this intervention will boost this measure of brain health) and then test it.
However, humans aren’t generally great at making short term decisions for long term gains. In other words: if it’s rainy out, or you’re a little pushed for time, you’re likely to take the car over walking regardless of what data point this adjusts in an overarching pattern that will affect your brain’s amyloid-β clean-up rates in 5–20 years time.
Nine days
The study we’re going to look at today was a 9-day observational study, using smartphone-based tracking with check-ins every 3½ hours, with participants reporting their physical activity as light, moderate, or intense (these terms were defined and exemplified, so that everyone involved was singing from the same songsheet in terms of what activities constitute what intensity).
The sample size was reasonable (n=204) and was generally heterogenous sample (i.e. varied in terms of sex, racial background, and fitness level) of New Yorkers aged 40–65.
So, the input variable was activity level, and the output variable was cognitive fitness.
As to how they measured the output, two brain games assessed:
- cognitive processing speed, and
- working memory (a proxy for executive function).
What they found:
- participants active within the last 3½ hours had faster processing speed, equivalent to being four years younger
- response times in the working memory (for: executive function) task reflected similar processing speed improvements, for participants active in the last 3½ hours
And, which is important to note,
âťťThis benefit was observed regardless of whether the activities they reported were higher intensity (e.g., running/jogging) or lower intensity (e.g., walking, chores).âťž
Source: Cognitive Health Benefits of Everyday Physical Activity in a Diverse Sample of Middle-Aged Adults
Practical take-away:
Move more often! At least every couple of hours (when not sleeping)!
The benefits will benefit you in the now, as well as down the line.

If Your Adult Kid Calls In Crisis…
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.
Parent(s) To The Rescue?
We’ve written before about the very common (yes, really, it is common) phenomenon of estrangement between parents and adult children:
Family Estrangement & How To Fix It
We’ve also written about the juggling act that can be…
Managing Sibling Relationships In Adult Life
…which includes dealing with such situations as supporting each other through difficult times, while still maintaining healthy boundaries.
But what about when one’s [adult] child is in crisis?
When a parent’s job never ends
Hopefully, we have not been estranged (or worse, bereaved) by our children.
In which case, when crisis hits, we are likely to be amongst the first to whom our children will reach out for support. Naturally, we will want to help. But how can we do that, and where (if applicable) to draw the line?
No “helicopter parenting”
If you’ve not heard the term “helicopter parenting”, it refers to the sort of parents who hover around, waiting to swoop in at a moment’s notice.
This is most often applied to parents of kids of university age and downwards, but it’s worth keeping it in mind at any age.
After all, we do want our kids to be able to solve their own problems if possible!
So, if you’ve ever advised your kid to “take a deep breath and count to 10” (or even if you haven’t), then, consider doing that too, and then…
Listen first!
If your first reaction isn’t to join them in panic, it might be to groan and “oh not again”. But for now, quietly shelve that, and listen to whatever it is.
See also: Active Listening (Without Sounding Like A Furby)
And certainly, do your best to maintain your own calm while listening. Your kid is in all likelihood looking to you to be the rock in the storm, so let’s be that.
Empower them, if you can
Maybe they just needed to vent. If so, the above will probably cover it.
More likely, they need help.
Perhaps they need guidance, from your greater life experience. Sometimes things that can seem like overwhelming challenges to one person, are a thing we dealt with 20 or more years ago (it probably felt overwhelming to us at the time, too, but here we are, the other side of it).
Tip: ask “are you looking for my guidance/advice/etc?” before offering it. Doing so will make it much more likely to be accepted rather than rejected as unsolicited advice.
Chances are, they will take the life-ring offered.
It could be that that’s not what they had in mind, and they’re looking for material support. If so…
When it’s about money or similar
Tip: it’s worth thinking about this sort of thing in advance (now is great, if you have adult kids), and ask yourself nowwhat you’d be prepared to give in that regard, e.g:
- if they need money, how much (if any) are you willing and able to provide?
- if they want/need to come stay with you, how prepared are you for that (including: if they want/need to actually move back in with you for a while, which is increasingly common these days)?
Having these answers in your head ready will make the conversation a lot less difficult in the moment, and will avoid you giving a knee-jerk response you might regret (in either direction).
Have a counteroffer up your sleeve if necessary
Maybe:
- you can’t solve their life problem for them, but you can help them find a therapist (if applicable, for example)
- you can’t solve their money problem for them, but you can help them find a free debt advice service (if applicable, for example)
- you can’t solve their residence problem for them, but you can help them find a service that can help with that (if applicable, for example)
You don’t need to brainstorm now for every option; you’re a parent, not Batman. But it’s a lot easier to think through such hypothetical thought-experiments now, than it will be with your fraught kid on the phone later.
Magic words to remember: “Let’s find a way through this for you”
Don’t forget to look after yourself
Many of us, as parents, will tend to not think twice before sacrificing something for our kid(s). That’s generally laudable, but we must avoid accidentally becoming “the giving tree” who has nothing left for ourself, and that includes our mental energy and our personal peace.
That doesn’t mean that when our kid comes in crisis we say “Shh, stop disturbing my personal peace”, but it does mean that we remember to keep at least some boundaries (also figure out now what they are, too!), and to take care of ourselves too.

10 Simple Japanese Habits For Healthier & Longer Life
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 don’t have to be Japanese or live in Okinawa to enjoy the benefits of healthy longevity. A lot of it comes down to simple habits:
Easy to implement
We’ll not keep the 10 habits a mystery; they are:
- Start the day with hot water: drinking hot water in the morning helps with hydration, warming the body, and aiding digestion.
- Enjoy a hearty breakfast: Japanese breakfasts are traditionally filling, nutritious, and help promote energy and longevity. Typical components include rice, miso soup, fish, and pickles.
- Take balanced meals: Japanese education emphasizes nutrition from a young age, promoting balanced meals with proteins, fiber, and vitamins & minerals.
- Enjoy fermented foods: fermented foods, such as nattĹŤ and soy-based condiments, support digestion, heart health, and the immune system.
- Drink green tea and matcha: both are rich in health benefits; preparing matcha mindfully adds a peaceful ritual to daily life too.
- Keep the “80% full” rule: “hara hachi bu” encourages eating until 80% full, which can improve longevity and, of course, prevent overeating.
- Use multiple small dishes: small servings and a variety of dishes help prevent overeating and ensure a diverse intake of nutrients.
- Gratitude before and after meals: saying “itadakimasu” and “gochisousama” promotes mindful eating, and afterwards, good digestion. Speaking Japanese is of course not the key factor here, but rather, do give yourself a moment of reflection before and after meals.
- Use vinegar in cooking: vinegar, often used in sushi rice and sauces like ponzu, adds flavor and offers health benefits, mostly pertaining to blood sugar balance.
- Eat slowly: Eating at a slower pace will improve digestion, and can enhance satiety and prevent accidentally overeating.

Cool As A Cucumber
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.
Cucumber Extract Beats Glucosamine & Chondroitin… At 1/135th Of The Dose?!
Do you take glucosamine & chondroitin supplements for your bone-and-joint health?
Or perhaps, like many, you take them intermittently because they mean taking several large tablets a day. Or maybe you don’t take them at all because they generally contain ingredients derived from shellfish?
Cucumber extract has your back! (and your knees, and your hips, and…)
It’s plant-derived (being from botanical cucumbers, not sea cucumbers, the aquatic animal!) and requires only 1/135th of the dosage to produce twice the benefits!
Distilling the study to its absolute bare bones for your convenience:
- Cucumber extract (10mg) was pitted against glucosamine & chondroitin (1350mg)
- Cucumber extract performed around 50% better than G&C after 30 days
- Cucumber extract performed more than 200% better than G&C after 180 days
In conclusion, this study indicates that, in very lay terms:
Cucumber extract blows glucosamine & chondroitin out of the water as a treatment and preventative for joint pain
