What If You Were Born Old and Got Younger?

Being born old and getting younger sounds like the dream. It would turn your whole life upside down. And your own body has already done it once. what if you aged backwards | born old and got younger | reverse aging | immortal jellyfish | why do we age | can humans reverse aging | animated what if Imagine the nurse handing your mum a newborn with white hair, wrinkles and no teeth. Congratulations, it's a grandpa. In this animated what if story, you live your whole life backwards: starting school with a walking stick at five, a 20-year-old grandpa doing backflips in the garden, and the best years of your life landing right in the middle. Then we find out why real bodies get old: think of your body as a brand new bike that collects a tiny scratch every day, with a repair crew that fixes almost all of it. We meet the animals that found a better deal, like the Greenland shark that may live for centuries and the naked mole-rat that doesn't get more likely to die as it ages, and the one animal that really does go backwards. And the twist: you started life as a cell that was already decades old, and before you were even born, you got younger. If you could start at eighty and end at zero, would you do it?
