It starts off easy. You're a baby, and no responsibilities are expected of you. And then you start school. And once you're a teenager,
your parents will expect more and more. Then, when you move out, you have to keep a job, and
eventually a family. On top of all this, you have to stay alive through
everything life throws at you. You have choices, and lots of experiences to be had.
But what's the reward for going through all the tough times? Death. Yep, you'll just die no matter what. Some religions believe there is an "afterlife", and I believe there is too. But if there turns out to not be an afterlife, then I'll be pissed. (Or not, since I'd be too dead to be pissed.)
