If I died right now I wouldn't be able to make a wish because I'd be dead. *snicker*
If I'm going to die in a few seconds why would I waste the wish on me? I'd probably die before it came true. What a waste. I'd probably use to wish for just general betterment, wellbeing and happiness for my family and friends (probably not all, lol. But I've got people in mind :p).

No wait. Since I'd have to be alive to make the wish, and ther'd be a slight chnace it'd come true in time if it was for me...then I'd wish to stay alive.
