Let's see:
1) Rugby: I used to train on Tuesdays and Thursdays -- to play on Saturdays. Due to a severe injury, I now play twice a week, just for the fun of it. And I follow nearly every single league out there.
2) Polo: Been playing it since I was 6, and it's a wonderful sport. I now play it once a week, maybe twice if I have the time. Don't really like watching it though.
3) Football: Yet to know an Argentinian that doesn't like/play football. Although with the current flea-like players mania I've been relegated in the Uni team. I can play #9 or #2. I watch the Argentinian League only.
4) Basketball: I used to follow the NBA back in the times of Jordan, Malone, Pippen and Reggie Miller. I picked it up after the OG in Athens, and play it every now and then. Used to watch most NBA games quite often, until most players became retarded show-offs.
5) Swimming: I started to swim regularly after I shattered my spine years ago, and have come to like it. It's so relaxing...
6) Tennis: Lovely sport, but I suck at it. All I can do is serve well. I am a fan of Roger Federer (then, who isn't?)
