Cool vid. I used to play rugby in college as a club sport. I had a great time. Have taken my share of hits, and had my share of great hits on opponents. All in all, it sorta taught me the rejuvenation that can be had from a good ol' fashion ass-whooping. No matter how hard I trained, I would always hurt the day after games. It's a good hurt, though.
I never sustained any overly serious injuries. I fractured a finger, once, but that was the only bone I ever broke. Nearly broke my nose, once, and my toe another time. Surprisingly, when played with proper form, the game is pretty safe. That's my opinion, at least.
