I disagree with the exercising part. Playing pick-up and adult league sports around town is far more satisfying and less boring than an elliptical or treadmill machine. As a bonus, you get to satisfy some of your social needs as well.

I play Ultimate Frisbee and Basketball. I sucked at first, but eventually it taught my brain to think and react in new ways and I got better - which is pretty cool! For a guy like me who moves to a new city every two years, the social benefit of being part of the Ultimate Frisbee network cannot be overstated.
