I feel it’s the ultimate hubris to think we can cheat death.

And if we were meant to fly we'd have wings, and diseases are the gods punishing us for our sins.

Moreover, why would you want immortality?

I don't know about immortality, but I'd definitely like more than 80 years, and I'd like to be in good health for as long as I am alive.

Many books of fiction and poetry discuss the curse of immortality.

Yes, and those are almost entirely cope.
