The Jellyfish That Rewinds Aging

“Okay, this sounds fake… but there is a jellyfish that can basically reverse its age.

It’s called the immortal jellyfish — Turritopsis dohrnii. When it gets injured, sick,

or even old, it doesn’t just die. Instead, it rewinds its body

back to its baby form and starts life all over again. Imagine breaking your arm and your

body just says, ‘Nope — restart life!’ and you become a kid again. Scientists are studying

it to understand aging, regeneration, and maybe even human medicine…

but for now, the jellyfish is the closest thing we’ve found to real biological immortality.

Would you restart life if you could… or stay your age right now?”
