Would you be immortal if you could? In any way, not just living forever.
(Because even if you lived forever, you could start rotting, and all that would be left of you would be an animate skeleton... And I'm not sure you can enjoy life that much like that...)
I wouldn't, because knowing that I'm not doing to last forever makes me work harder to get what I want done in life done. (Cuz death is like the ultimate deadline. x3)
