ELI5 Turtles longevity

Can you explain why turtles live very long ? And if we know why can’t we learn from their bodies and use this in research to promote longevity in humans ?

Turtles have a very low metabolism, their heart beats slowly, they breathe slowly, they process food slowly. This was advantageous for their evolution as they were able to sustain long periods of drought or hunger and survive. 

This slowed pace allowed them to live longer lives, as the stress of situations wasn’t as impactful to them.

For humans, most people have kids between 20-30, in older times it was earlier. Their genetic material has already been passed on so it’s not as important for humans to live longer.
