For thousands of years people have searched for a way to avoid the inevitable. Fountain of Youth, exercise programs, potions, spells, ointments...
The truth of the matter was expressed quite well, (though humorously) in the movie Moonstruck:
Rose:
I just want you to know no matter what you do, you’re gonna die, just like everybody else.
Cosmo Castorini:
Thank you, Rose.
Sigh.
It’s not only about postponing death, it’s also about trying not to feel any worse than necessary before you get there.
