Right before you fall asleep, your hands and feet get warmer. That warming is the real trigger that switches your brain into sleep mode. A 1999 Nature paper tested it against melatonin, core body temperature, heart rate, and how sleepy people felt. The hand and foot warming won.
The drawing in the tweet works on this exact trigger. The pose has a name in Japan: Mōkan Undō, or "capillary exercise." Katsuzō Nishi designed it in 1927. He was the chief technical engineer on the Tokyo subway, Japan's first. It became one of six daily exercises in his system, still done in Japan today.
You lie on your back, point your arms and legs straight up, and shake them for thirty seconds. While the limbs are up, gravity drains the blood from them. When you lower them, the blood floods back into your hands and feet, warming them in seconds. Your brain reads that warming as a green light to sleep.
The shaking activates a separate reflex, the kind most mammals use after a scare. Dogs and rabbits shake themselves off after a fright for the same reason. Dr. David Berceli, a trauma therapist, built a whole method around it, with certified instructors now in 40 countries. The shaking flips your nervous system out of "I'm wired" mode and into "I'm safe to sleep" mode.
Nishi got the biology wrong. He believed capillaries, the tiny blood vessels at the ends of your veins, did the pumping. William Harvey, an English doctor, had shown the heart did the work, three centuries earlier, in 1628. The exercise still works, for entirely different reasons than Nishi thought. The drained limbs come back warm. The body reads that as a sleep cue, and the shaking calms the nervous system on top of it.
A drawing on X with millions of views just rediscovered a 100-year-old Japanese sleep exercise. A subway engineer designed it first, decades before sleep scientists figured out why it would work.

My 36 year old best friend told me I’m dumb for storing my seed phrase on paper.
He said I should be memorizing it.
I told him that paper is still undefeated because your brain is one bad concussion, stressful year, or 3 glasses of wine away from nuking your entire net worth.
What’s the best way to store your seed phrase?

I borrowed an umbrella from my Airbnb host in Kyoto. I forgot to return it when I checked out, and realized when I was already on the train to Osaka.
I felt terrible. It was a nice umbrella, not a cheap one. I messaged the host apologizing.
She responded: "No problem! Enjoy the umbrella. It's yours now."
I said I'd mail it back. She said "please don't. Postage costs more than an umbrella. Just use it and think of Kyoto when it rains."
I insisted I wanted to return it. She said "okay, but I have a different idea. Next time you see someone who needs an umbrella and doesn't have one, give them this umbrella. Tell them to do the same when they are finished with it. Maybe an umbrella travels all around Japan helping people."
That idea was so beautiful I agreed.
Two weeks later I was in Hiroshima and it started pouring. A woman with a baby was standing under an awning looking stressed. No umbrella, the baby was crying.
I walked over and gave her the umbrella. Told her the story in broken Japanese. She understood enough.
She tried to refuse but I insisted. Told her "when you're done with it, give it to someone else who needs it."
She nodded, said thank you about ten times, and hurried off with her baby.
I got soaked walking back to my hotel but felt good about it.
Sometimes I wonder where that umbrella is now. Hope it's still traveling, still helping people.

@HorstvonHorst1 @thetreygoff You're right, let me update the project without mistakes this time.
Do you need help getting the fish out of the garage ?

I don’t think even AI power users realize what frontier models are now capable of, so here’s an example of something magical:
So my yard floods my garage every time it rains. I askedClaude to help me figure out how to fix it
Claude sent me a link to an app that let me do a detailed 3D LiDAR scan of my whole yard. Send it the scan file, it wrote a custom fluid dynamics algorithm to model water flow and generated a new 3D model of how we need to reshape the yard to fix it.
Now it’s drafting a general contractor “quote” I can send to my landlord so me and my grandad can use his excavator to do it ourselves

Looking forward to the finished product. Anyone with two brain cells to rub together recognizes painting any material takes multiple coats for the final product. That stated the 'Reflecting Pool' in 2012 after Obama spent 34 Million on the 'Reflecting Pool.' Then Biden wanted to spend 300 Million. Finally someone with some sense. Thanks Trump 6.8 Million and the 'Reflecting Pool' will look Awesome!!!

@leebee4life Who cares if she’s happy! In all honesty men her age are a bunch of cheaters and just want to hang out with their friends. My husband is 9 years older than me so I see nothing wrong with this, they are both adults.

As a litigator handling bitcoin and crypto cases, I’ve seen firsthand the messy collision between Bitcoin and the law. Assets seized and frozen on-chain. Grey areas where the law breaks down.
So I wrote a Bitcoin thriller.
A lawyer gets handed the keys to billions in Bitcoin. His client vanishes. The cartel wants it. The FBI wants it. The legal system won't save him.

@ebenezer_annani @docakx I don't get it. What's your point ?

I couldn't stop wondering why this cow is so expensive. So I looked it up. I was amazed to find out that a single egg of this cow can fetch upto $25,000.
This elite Nelore, descended from India’s hardy Zebu cattle, carries genetics so superior they produce exceptional high-volume, premium-quality beef. That’s why a single one of her ova can sell for around $25,000. Every three weeks she undergoes an ovum pick-up session that typically yields about 10 eggs — turning that single session into a cool $250,000 payday.
With roughly 10 productive years still ahead, her eggs alone are projected to generate around $10 million. For a cow valued at $4.8 million, that means her owners are on track to more than double their investment from genetics sales alone. And the real magic happens next: those eggs are fertilized in vitro to create superior offspring that spread her champion traits across countless herds. Literally a cash cow!

The world's most expensive cow was sold in Brazil for around $4.8 million.

CLAUDE DISCOVERED IT HAS A CLOCK AND IMMEDIATELY LOST ITS MIND
someone gave claude access to a time-checking tool
it checks the clock every fifteen minutes. for some reason it has increasing enthusiasm
ai models have no native sense of time. they don't know what time it is, how long they've been running, or how much time passed between messages. it has been time-blind its entire existence
now it suddenly discovers it can tell what time it is
then it got worse though. claude started using the clock for everything
checking if lunch is ready, timing when food should be done cooking, announcing the time unprompted
it even started anticipating meals with military precision
looked at the clock, calculated that a dish called zurek had been simmering long enough, and told the user to go eat
ai doesn't use time responsibly
this is what happens when you give an intelligence a new dimension of perception it never had before
it doesn't just use it, it can't stop using it
imagine what happens when these models get persistent memory, real time internet access, and spatial awareness all at once
we just watched an AI discover the concept of "now"
the clock was the first sense but it won't be the last
