What kind of immortality are we talking here? Do I live FOREVER forever? Will I be floating in the void, suffocating eternally but unable to die, long after the heat death of the universe? Or is it like, vampire-type immortality where there are rules and I can be killed in some specific way?
Yup. The choice is obvious. And a quadrillion years is the best case scenario, assuming humanity creates a spacefaring civilization until heat death. Your torture could start much sooner. Say a nuclear war breaks out. Your city is hit, you don’t die. But you’re buried under a city’s worth of rubble now. Good luck getting out from under that within ten thousand years.
