7. Curling
You were waiting for it, and here it is at #7. While everyone seems to think curling is the easiest sport in the world and usually is the #1 theme of Facebook posts during the Winter Olympics, it is hard and that whole sweeping thing takes a toll. Anyway – the first time I tried curling, the guy sweeping next to me lost his footing and slammed his head on the ice. Blood everywhere. A few minutes later he was being stretchered out by paramedics. Curling is a blood sport and don’t let anyone convince you otherwise.
