Don't die. The thing is, everyone dies. No sense in getting worked up about it. LIVE. That's the best advice anyone could give.
ps-everyone worries about this at some point, usually it comes after the "I'll never die" phase in your teens. I'm scared shitless to die, but there's nothing I can do about it. So I smoke another cig, drink another vodka+coke, and hopefully mix in a blunt. In between all that, I gotta figure out how to live. One day I'll figure it out, or I'll be dead. It's all the same to me.
BTW before you die, how about joining the queue for free ipods/ free flat screens for us. We could use all the help we can get
