Pretty sure that's not it. There's a reason there's so much discontent and depression in our society. In large social studies that measure Huge samples of people, the US ranks, by far, the lowest in terms of happiness and the highest in depression when compared to other 1st world countries and even many 3rd world countries. Interestingly, the people that seem happiest are those Not in the riches countries and that aren't in the lower class. They live comfortable lives with food and shelter and actually have a life to live and much more culture in their countries than we have in the US and other 1st world, money based societies. We're all bored and discontent because we don't have anything to really do. Our jobs, where we used to do some real "living" like hunting or gathering wood, etc, are monotonous and generally meaningless. MTBing at least gives you a taste of reality and nature and gets your blood flowing once in a while when you're bombing down some hill, trying to rip around turns at speed or hitting jumps.
