Yeah, and even though you're fighting for your life every day then, it seems so much simpler and not so bad once you've developed a community that can share the chores. I watched this documentary on David Beckham's trip to the native tribes in Brazil. They're all very happy with their life. Everyone is very close and it's nice because all your time is spent with family. They get to be with nature all day, have fun and joke while collecting and preparing meals for the tribe, and afterwards they all sing and dance.
