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.
No memory = no point in doing it.
If you don’t remember something, it might as well have never happened.
Besides, I’m already sick of this time around, and my genetics were fucked to begin with. Give me a redo with my memories and a new body, and then we might have something.
