Inspired by this article about a jellyfish that doesn’t die of old age, injury or poor conditions, it just reverts back to a juvenile state and is reborn genetically identical. If you could be reborn, as you, would you want to?
Edit: Just the physical you, genetic and presumably epigenetic, no memory.
I came to the same conclusion after a while. Then I thought how some people view progeny as a form of immortality. This is maybe a tad more direct.
