I'm 36, just found out I had it like about a year ago. It's a ringing in the ears for anybody that doesn't know, it's like after you go to a rock concert and your ears still ring? It's like that, just 24/7. I think I've had it for a very long time, maybe forever, but I just last year realized it was a condition, not something normal. Anyway looking back I think about those unmuffled VW engines, grinding and hammering, working in the oil field, concerts, all that stuff I didn't use ear protection for, and I'm like, what was I thinking?!? Does anybody else have it? How do you deal? Somedays it bugs me like hell, somedays I don't even remember I have it. I just try to have a fan on for background noise or something when I sleep, and it's fairly rare to be in a quiet environment anyway. I use the hell out of some earplugs today! I see people grinding and stuff without them and I think they're nuts, but nobody thinks it'll happen to them. I didn't even know it existed when I started working on cars.
