ELI5: Why am I utterly terrified of death?
gpt
I think the best explanation is the evolutionary one. Those people (and other animals) who weren't absolutely terrified of death didn't put out as much effort to avoid it and might have even welcomed it.

It's better from a survival perspective to be scared and wrong (you're just embarrassed) than relaxed and wrong (you get eaten by a tiger). So the neurotic ones tended to survive longer.

(But of course, it's not better on a daily basis to feel that way.)
