I love this post. As a hacker myself I can relate. I did not do much while at school - that pretty much took all my time. Also, "regular" sports did not appeal to me. I started taking up martial arts as soon as I started working and it has completely changed my life. It clears my head, keeps me fit.

I never liked the idea of hitting the gym just so you could have a "beach body". The idea of learning a new skill (or set of skills in my case) appealed to me. Having a fit and healthy body was a side effect. The inverse wasn't true, - lifting weights at the gym wouldn't yield any additional skill so it definitely did not appeal to me.

I guess what I'm trying to say is that if you find the physical equivalent to hacking - whether it's rock climbing, free running, or doing wushu - it's fun and will also keep you in shape.
