In twenty years, you'll have the same brains, only they work better (99% of the time). Maybe, slower. Wait until then until you starting talking shit about wanting to die. If you want to die now, then I think we should all jump all over you and offer you help. That girl up there is 19. Compare that with her life when she was 2. Everyday, we fill up our brains (mmm, brains...) with memories and exercise our intellectual capabilities on mundane activities.

I think that 70 year-olds are geniuses, and, they know enough to keep their mouth shut.
