We watched the Olympics Judo qualifying matches streaming online last night (photo, above, of Brit Craig Fallon, by the Telegraph). It was great. It was also pretty complicated for a sport that mostly involves making your opponent bleed and/or pass out. Its incredible that there is a legitimate sport where choking your opponent until he (or she) goes unconscious is a valid way to win.
I'll be interested in seeing how judo compares to Tae Kwon do, since I imagine we'll be watching that, too.
