I didn't watch futarama and I don't even know what that is. The main thing holding people back is other people, which is their loved ones. However if you feel the world is shit anyway and you don't really have anyone to rely on then you would make the journey. You would be the same age as you are right now only in a new world a millennium from now. I definitely want to make the journey but I'm like most of the guys here, I can't leave behind my family as much as I hate this shitty place.
