Olson suggests that a connection with nature stabilizes us mentally. Part of me sees truth in this, sitting on green grass watching the clouds go by or just chilling out by a river is extremely relaxing and centering. When we are surrounded by concrete and steel all day and don't see what we come from it can be hard on the mind. We live by a man-mad schedule and push ourselves to hard. Before civilization we lived by ours needs, hunted when we were hungry, slept when we got tired. Now we sleep after we stay up to late doing calc homework which fries our minds and then wake up to early to a buzzing alarm clock to go to chem which sucks. Maybe that;s just me but id rather go to bed when it got dark and wake up with the sun. Go steal some chicken eggs for breakfast and go hunting for lunch. Just be natural and relax. But that's not to say that living natural isn't stressful, but doing things that you know are primal and not just a job or work or just class gives us meaning in life.
