I like to watch sports generally and I also watch the Winter Olympics.
I don't really know much about any of the winter sports - I have never skied or snowboarded myself - but I find it interesting to figure out the rules and specifics of each discipline.
So far I have watched bits of snowboarding in the half pipe, curling, biathlon, skiathlon, figure skating, big air skiing, short track, speed skating, alpine skiing...
I do like the summer games better though. The sports are more familiar to me and the athletes are not so hooded and masked
