Wado-Ryu Karate-Do, it's a mix of shotokan style karate and shorinryu jiu-jitsu, has more locks, throws, manipulation than most karate styles and it has a distinctive "blocking" style. Plus I get to beat up and get beaten up every friday.
Cycling, pretty much my way of moving from A to B, sometimes I do longer trips, longest one was over twelve hundred kilometers.
Underwater Rugby, currently on hiatus due to not finding a good group to play with.
