90% of them will damage their hearing but not get any significant tinnitus, so...
I tend to tell teenagers they're being dumb when I see it, and describe my own tinnitus. Adults I mostly just let adult on their own, though I will say that a good number of my own close friends are a lot more protective of their hearing than they were before I told them all about my own issues.

If I remember correctly, there was a study that asked the participants to estimate their chances of developing various diseases, getting into various accidents and dying over the next 1, 5, 10, and 20 years. The healthy people had significantly underestimated all of those probabilities. The people who were clinically depressed were the group that got the closest to a correct estimate of those probabilities. As I always say: A pessimist is an experienced optimist. You can ignore reality, but you won't be able to ignore the consequences of ignoring reality.
Eh, so what? There are serious, unpleasant correlates to living with long-term depression. It's one thing to be "optimistic to a fault", as in not wearing earplugs to loud concerts, not driving with airbags/seatbelts, etc -- but it's quite another to ruminate on things past the point of useful anxiety.
People underestimate their mortality because mostly people would rather be happy in the moment than be fixated on the inevitability of illness and death. I think people who manage to live more in the moment are, generally, happier -- provided they don't let their general optimism lead to obvious dumb decisions.
Bottom line: something shitty and bad is going to happen to my health over the next 40 years, possibly much sooner. I take reasonable precautions to protect myself, but I don't think that becoming "pessimistic" does me any good. I approach life with a sort of
cautious optimism which is certainly informed by the health issues I've had, the people I've watched die or worse, etc -- but having
optimism tempered by objectivity is a very different thing than being pessimistic, let along "clinically depressed". No one really benefits from the latter.
Some people, when they have suffered past some point, lose the plot as far as empathy and rationality, and it's pretty sad to watch. On the other hand, often times people just need to vent, which is cool and good.
