Part of my fear of death is missing out on the future. Well I get to visit other planets? Will I get to see the resolution to quantum mechanics / relativity? Will I get to see extraterrestrial life? Will I get to see humanity spread among the stars?
I desperately want to see those things. And I'm extremely scared of missing out just because of how frail human bodies are.
Rather because I think I would enjoy being able to learn about more things.
Wanting to be immortal specifically to escape death seems odd to me.
