Curling is the least dangerous ice-based sport I can think of. Unlike hockey, it involves no fast-moving projectiles or expectations of physical violence, and unlike, say, figure skating, it requires no blades, spinning, or jumping. And, OK, it’s not super exciting to watch, but it has its moments. If you want to try your hand at curling, well, let’s hope you live in one of the few parts of the world where curling rinks are common; if not, you’re pretty much out of luck. But when the next Winter Olympics roll around, just remember: this weird little sport is worth your attention! It’s cool both literally and figuratively.
