I'd be curious to see some data summaries with skier/snowboarder age demographics relative to the population distribution. Along with the skateboard and biking activity participation. My experience has been that from the teens through the twenties many I know remained active in these types of activities with a lag in the late 20s early 30s then a renewed enthusiasm late 30s through the 40s. But, after all that, in spite of the professed intentions and excitement through the 40s, quite a few of my friends, in fact most of them, STOPPED the more high impact activities between age 50 and 55. It seems that all the older friends I have (outside of these forums) want to do is light hiking, casual bike riding, but not all that often, but most of them golf and play pretty often. Does that progression sound familiar to others here and the folks you know? Is there any data that suggests a giant drop in the participation rates for skiing and snowboarding when people hit their fifties?
