There is a guy who doesn't live very far from me, who was a professional NHL player. He was an expert skater.

He was at the outdoor rink with his young kids, just standing there on the ice and lost his balance. Cracked his head on the ice and now has permanent brain damage. His personality is even different.

He spends his time talking to folks about the importance of head protection, because it has nothing to do with your skating ability.
