This reminds me of the only time I tried downhill skiing. I was one of the adult supervisors on my kids' school based ski trip and tried it. I got about a third of the way down the medium trail, worrying about running over some poor kid. when I fell. I thought that the snow was supposed to be powdery and soft...WRONG! I fell backwards and hit my head, and I actually saw stars! My daughter skied down to me ... like a pro ... and asked if I was OK. Besides being very embarrassed my head hurt like crazy, but I made it back down to the bottom. Lesson learned, and that is the ONLY time I have skied.
