There's fucking kooks my age and there are some decent dudes 15 years younger. If you're asking how to deal with the weirdos you can't identify with, that's a person problem not an activity related issue. Venture out to new skateparks, ask dudes if they want to be Instagram friends as you gently put your hand on their bike.
The other activities I engross myself in are studying, growing plants, and I've grown very accustomed to watching tv and using the internet.
