The healthiest brains on Earth belong to people who can't read.

USC scientists spent 15 years proving it.

They found modern "brain optimization" ages your brain 70% faster.

Once you see it, you can't unsee it.

And you'll question every supplement, app, "hack" you've tried:🧵
Meet the Tsimane people of Bolivia:

• Population of 16,000
• Live in Amazon rainforest
• Hunt, fish, farm for survival
• No electricity, no smartphones
• Average 6-7 miles walking daily

And their brains? Youngest ever studied by modern science.

The British government wanted fewer cobras in Delhi.

So they offered money for every dead cobra.

Result? The cobra population EXPLODED.

This "solution" backfired so spectacularly––It's now a fundamental psychological principle studied at Harvard, Stanford, and MIT: 🧵
Colonial India, British Raj era:

Delhi had a cobra problem. Venomous snakes were killing people.

British authorities did what seemed logical:

"We'll pay locals for every dead cobra they bring us."

What could go wrong?

ZEIGARNIK EFFECT.

Instagram, YouTube, and Netflix exploit it to trigger anxiety, depression, and ADHD-like symptoms.

But this "digital disease" has a cure.

A Soviet woman discovered it in a 1920s Berlin café (and her findings explain why you can't stop using your phone) 🧵 ⚠️ WARNING ⚠️

Once you understand this, you'll see manipulation everywhere... work, apps, even relationships.

Use this knowledge to build better relationships and protect others, not to exploit them.

Sun Tzu wrote The Art of War 2,500 years ago.

Today, it sits on the desks of Jeff Bezos, Mark Cuban, and every Fortune 500 CEO.

But most people think it's just an ancient military manual.

Here are the 10 secret tactics Silicon Valley uses to destroy competition: 🧵
Why does ancient warfare matter in the digital age?

Because business IS warfare.

• Market battles instead of physical ones
• Customer acquisition instead of territory
• Competitive advantage instead of tactical superiority

The fundamentals never change.

The Stanford Marshmallow Experiment is the most misunderstood study in psychology.

Ivy League schools, top CEOs, and child experts swear by it.

But the lead researcher spent 50 years proving it wrong.

What he discovered will shatter how you think about self-control forever: 🧵 Meet Walter Mischel:

• Stanford psychology professor
• Ran the famous experiment in 1972
• Followed the same kids for 50+ years

Discovered something that contradicts everything we believe about willpower

The real story is far more interesting...

Richard Feynman could explain quantum physics to a 5-year-old.

He won the Nobel Prize, cracked safes at Los Alamos, and learned to draw at age 44.

His secret? A 4-step learning method so powerful, it's used by Bill Gates and Elon Musk.

Here's how to master anything: 🧵
Meet Richard Feynman:

• Manhattan Project scientist
• Nobel Prize in Physics (1965)
• IQ of 125 (surprisingly "low" for a genius)
• "The Great Explainer" - legendary teacher

His superpower wasn't raw intelligence—it was learning HOW to learn.

In 1945, Honda was on the verge of collapse.

Their most valuable plant was bombed in war, forcing them close to bankruptcy.

Then their CEO discovered a hidden cheat code that erased over millions in debt and made Honda a $41.71 BILLION empire.

Here’s the story. 🧵 Born in 1906 to a poor family in, Japan, Honda faced tragedy early in life.

He lost 5 of his siblings to illness. But that didn’t stop his dream.

Fascinated by the smell and sound of engines, he dropped out of school at 15 to chase his dream, working with motors.
