This is why a wish to live forever is a bad idea because it can get all twisted. You’re still technically alive in suspended animation, but that’s not really gonna do you any good.
A wish for permanent youth would probably be better to avoid those situations where you find yourself wishing you were dead (i.e. buried alive underground – a situation grave enough to give an immortal nightmares).
Coincidentally, I saw a trailer for a new sci-fi movie about people paying for eternal youth, In Time. It has Justin Timberlake in it for some reason, which I find kinda strange.
