I think if I were the only, or among the very few immortal beings, that would be trboulbing. The constant pain of losing friends and loved one, along with the boredom of never seeing anything truly novel would get to me after a bit.
If it were the norm to live forever rather than the exception, though, I think I would be just fine.
Does it? If one could live forever, but chooses to sacrifice their life for the sake of a loved one, isn’t that even *more *of a sacrifice? You are not just giving up a finite number of years, but an infinite number of years.
OP because there is death and nonexistence, we have an incentive to make the most of our too, too limited shot at life and existence. But where for some that means love and sacrifice for others, others just go for maximum pleasure and display of power for themselves. So there is no teleological progression from mortality to high moral value.
And for crying out loud, nobody “chose love over immortality”. Our nonhuman ancestors were mortal for billions of years before sentient consciousness and moral sense arose as an emergent property of a more complex brain (or were infused into it by the Deity or alien monolith, if you will).
Ah, but wait…what about immortals having the sexy with mortals? Huh? What then? No love for Hercules amongst you mere mortals? How would we even play D&D without demi-gods? Have you fools never thought about that either? Ram your fucking 20 sided die up your arse, I’m with Hercules.
Love is a consequence of there being an advantage in pair-bonding to care for offspring, and in caring for that offspring itself rather than tossing the bawling poop-machine off of a cliff. It is a useful tool to help genes successfully create more genes.
I was under the impression that we age because there is no evolutionary pressure to keep us alive after reproductive age. So there is natural selection pressure to keep us alive long enough to birth and raise a new generation, after that evolution doesn’t care. So no selection pressure to make people live forever. Just pressure to live long enough to have kids that survive to reproductive age, after that your body falls to the powers of entropy.
Also supposedly some traits that are helpful when you are young are harmful when old. I don’t have examples, but I’ve heard some aspects of heart disease or dementia are due to traits that are helpful when you are young.
But anyway, we die because evolution has no incentive to keep us alive after we’ve procreated and our children have reached independence and maturity.
Supposedly thats a big part of it. Then again, turtles don’t care for their young and turtles can live hundreds of years. Who knows.
