Your Body Constantly Rebuilds Itself

Warning: your skin completely replaces itself every 27 days. You're basically

a human snake shedding your outer layer constantly without even noticing it. And get this,

your stomach gets a new lining every 3 to 4 days because the acid is so strong it would literally

digest itself otherwise. Your body is replacing parts faster than a car mechanic on overtime.

But here's the wildest part, your bones are busy too, completely regenerating

every 10 years. You're never actually the same person you were a decade ago,

at least not physically. Your body is literally rebuilding you while you sleep.
