Aging Isn't Wear And Tear—It's An Evolutionary Strategy

Why do we age? It turns out aging may not be a flaw or an accident — it may be something evolution built into your cells on purpose. Every second, trillions of your cells repair damage, destroy mutations, and rebuild your body. Your body fights harder to keep you alive than you ever realize. And yet, it still ages. Why? In this video, we explore the real science behind why humans age — from the Hayflick Limit and telomeres, to the terrifying reason your cells refuse to become immortal, to the evolutionary trade-off that may explain your entire lifespan. The answer is stranger, and more beautiful, than "your body simply wears out." If you love psychology, biology, evolution, and the strange questions hiding inside everyday life, subscribe to The Human Odd. What would you do if you could live forever?
