Here are some fun facts about the brain:

1. The brain is mostly fat: About 60% of your brain is made of fat, which helps it work properly.
2. Your brain is really powerful: It uses about 20% of your body's energy, even though it only weighs about 3 pounds (1.4 kg).
3. The brain has its own internet: There are billions of tiny connections between brain cells called neurons. They work like a big network, just like the internet.
4. You can't tickle yourself: When you try to tickle yourself, your brain knows it's you, so it doesn't send the "tickle signal". But if someone else tickles you, your brain gets the signal and makes you laugh.
5. Your brain can dream even before you're born: Scientists found that babies in the womb can have dreams just like adults.
6. The brain can fill in missing information: If you close one eye, your brain can still see the whole picture because it uses the information from the other eye.
7. It takes a while to wake up fully: When you wake up, it takes about 30 minutes for your brain to be fully awake and functioning.
