1. Your brain is the size of a large grapefruit, and it’s shaped sort of like a head of cauliflower. Its surface is wrinkled like a walnut, and it feels soft and squishy, like a lump of warm butter.
2. Your brain is connected to 30,000 miles (50,000 kilometers) of nerves that snake through your body like strings of licorice. They carry millions of messages to and from your brain every second—even when you’re asleep.
3. No computer on Earth is as powerful as your brain. It sends out about 6,000,000,000,000 messages every minute. And it can store up to 1,000,000,000,000,000,000,000,000 bits of information. Not bad for a 3-pound (1.4-kilogram) lump that’s 78 percent water and 10 percent fat!
4. The world-famous physicist Albert Einstein died in New Jersey in 1955. A doctor removed his brain so people could study it. But the brain got lost. Someone finally found it in a cooler in Kansas in 1978.
5. Which uses up more energy—running a race or taking a test? Seem like a no-brainer? Don’t answer too fast. Your brain uses up to 25 percent of the nutrients you get from food.
