In this video, I'll show you the three strongest scientific explanations for why we age: telomeres that shorten with each cell division, "zombie cells" that refuse to die and inflame the body from the inside, and the most disturbing reason of all—why evolution itself kind of "shrugged off" old age.

They're working for you right now. ⏱️ CHAPTERS 00:00 It's not time that ages you 01:02 Piece 1: Telomeres 01:47 The Hayflick Limit 02:16 Piece 2: Zombie Cells 03:22 Piece 3: Why Evolution Allows It 04:34 Putting the Three Pieces Together 05:03 Can it be Reversed? 05:26 What to do with this 🔔 Subscribe to Explaining It To Me — every day at 8 PM. #aging #telomeres #cells #science #longevity #whyweage #biology #health
