I'm 50+ and still have good hearing because I either walk out of places that are too loud (including Rolling Stones or other concerts if they are in bad venues) or I wear earplugs. I have since I was old enough to go to concerts. I keep two sets of plugs in the console in my car in case I go somewhere on the spur of the moment. I've been spied taking them after a set by band members, but often while they are stealthily removing theirs, too. I don't care if anyone notices--I can hear.
