Just a bit of tennis and martial arts. I'm a bit clumsy and get tired easily so I wasn't all that good at either.
I've always been curious about paintball though! A long time ago, I found one lying around and tried to break it open to get the paint out. But I couldn't just pinch it open, I had to whack it with a hammer! (...and then I had to clean up the mess.)
Maybe that one was a dud, but it seems like getting hit by one hard enough for it to pop would hurt!
