I used to do tons of sports, but sadly, I'm not that much into them anymore; I don't even watch them as much as I used to. Lately, however, I started going jogging and working out on an almost daily basis again, and more importantly, actually started enjoying it again.
Up until recently, I also used to play rugby at a local club. Even though I technically quit, I am still an official member of the club and stay ready to be called to action any time we have a shortage of players for a certain game (which can happen a lot), so I might find myself back on the field sooner than I think.
Another interesting sport I used to do at university is fencing, I can definitely recommend it if you have the chance to try it out.
I also love to try out gambling games of skill and luck other than poker, especially exotic ones like Hanafuda or Mahjong, I actually own a deck of cards/tiles for both of these games. It's a nice way to broaden your horizon a bit. Board games like chess or backgammon are also very interesting, even though I tend to gloriously suck at them, especially at chess.
I'm not much of a video gamer, but I also play them casually from time to time. For some reason, I tend to prefer the old stuff from the 80's and 90's, and I have a decent little collection that includes some obscurities like the Nintendo Virtual Boy and a pong console from the 70's.
And if all else fails, there's always drinking.
