1. Babies have more bones than adults. At birth, we have around 270 bones; many fuse over time into 206.
2. Your stomach gets a new lining every 3 days to prevent digesting itself.
3. Your heart can keep beating even when disconnected from your body (temporarily).
4. You shed about 8 pounds of skin a year—that’s a whole newborn in skin cells!
5. Some people can hear their own eyeballs move. It’s rare, but real.

The body is weirder—and more fascinating—than you think.
