Okay, I’ll admit it: I like to watch curling at the Winter Olympics, more than any other event except hockey (when it’s competitive) and maybe speed skating. Too bad the Americans can’t seem to win a single game. Both the men and women come close, then they miss a key shot. That’s the story of their Olympics.

Is there a reason why we segregate curling teams by sex? For many events, it’s obvious why we do this. But curling?
