well one reason i can think we're a bit older (i'm 45) is because we grew up in a more "hands on" age. i remember repairing and troubleshooting engines with my father and grandfather as a little kid, strapping up mufflers with safety wire and coffee cans, dicking around with drum brake star wheels, rebuilding 4 barrel holleys, cleaning the points with a matchbook, replacing rings on a lawnmower piston, etc. of course most of the time i was the flashlight holder, but i enjoyed every minute of it and it kickstarted my interest and it turned out to be a 4 decade hobby.
these days things are disposable and sanitized. people don't rebuild carbs, they call the repair guy who swaps it with a new one, or they throw the entire thing in the trash and buy a whole new snowblower. you wouldn't believe how many people look flabbergasted when they ask if i'm a mechanic and i tell them no, i work in IT. they can't believe someone might know how all this stuff works unless they do it for a living.
it's a rare kid that will turn their attention away from youtube to go help dad tear down the weedwacker or replace the struts on the family minivan.
