I find both of these options to have major faults.
The main fault that both of them have, to me anyway, is death, I don't want to die at all, it feels really bad. Why would you choose either? Somebody said up there that she hates the idea of growing old, and who could blame her, aging is chitty, and dying when you are old is no easy task and very painful, not to mention it hurts your loved ones immensely also to see you go through it. But dying young is also a horrible thing, that also hurts your loved ones and you.
Have you ever seen anybody die? It's horrible.
Don't choose either, why would you just accept your demise like that?
