[00:00:00]So, what do we make of the Greenland shark? Up to 500 years old, possibly older, moves at 1.6 km/h, functionally blind, reached maturity at 150, shows almost no signs of cellular aging, is currently being studied by scientists trying to understand how to extend human life. It was there when every single human alive today was born.
