When I snowboarded for the first time, I ended up accidentally going very, very fast and when I tried to slow down just ended up travelling backwards. Then I hit a ridge of snow, flipped over and head-planted.
I had a helmet on, but I still felt pretty sick for a while after. I suspect it was a mild concussion...
