You can get hurt in the strangest way sometimes.
I've been teaching my daughter, so there is a lot of slow riding (mostly switch) on green runs. Yesterday, I'm riding just below her, looking up at her coming down and giving her encouragement, when I catch my heel edge. Landed hard on my hip and smacked my head hard. The helmet looks OK, but had it not been there, what was just a painful fall would have been a concussion, and I have been concussed before, so it doesnt take much. Goes to show you, you can wipe out anywhere.
I have a good bruise on my hip... left my butt pad at home.
