I hack and I'm actively involved in MMA. It's a rare combo, but I like the way it is so completely opposite to hacking. With hacking, a lot of time goes into the thought process. With MMA, you don't have time for thinking, it's all about training your reflexes. I also like the way there are a lot of physics involved: leveraging, momentum, et al. The sport has a bit of a knuckelhead image to it, but the guys I train with vary from construction workers to sales/IT guys. We all have to show up at our jobs tomorrow, so we don't beat the crap out of each other, although things can get pretty tough sometimes...
