I'm in the same situation - skateboarded from my mid-teens to my early thirties, twenty years give or take, then moved to the Swiss Alps so took up snowboarding. I don't skate anymore, so spend the summer doing short bike rides to keep fit for the winter season. And I agree, know many skateboarders my age who have had knee ops. So far I've been OK, but I know it's only a matter of time.
