I suspect, if we were to put this into a "class" situation, most vets with an active duty status during a "situation" will have it. Also, many of us who attended, participated in, or just were a part of a generational music thing would also have it....
I, personally have it covered on all fronts. To start with shooting at a young age with no hearing protection. Who knew....
Then there were those early money making days of 1964-67 with thousands of watts of amplifiers 6-15 ft. behind me or fifty ft in front of me... Then too much of that other stuff males of my generation were privlidged to participate in, you all get the picture I know....
I hear it every day.. I am hearing it right now as several others have said. I guess I have learned to "tune it out" in a way. Like Broke Tooth, my eyes, although I now wear glasses, have been good to me. Thank God!
Now, when I shoot guns, which is almost every day starting when the weather gets ok here, I wear plugs and muffs... sometimes only one or the other, sometimes both.
Ya cant get rid of it. Ya just have to let it become a part of who you are and go for it. Truthfully, I did not even notice it until I started typing this. Now I hear it. Has it messed up my life... yea, kinda. Same as several have posted.. If there is background nois I am in a spot. In the classroom I just tell my students to shut up and let the one guy speak cause the ole deaf sob cant hear otherwise. My wife, God bless her, has adapted. She trys to speak directly at me facing me... That helps... When we are out she will touch my arm and that lets me know to look at her. If we are in a crouded place with a lot of background noise, like a resturant, I will try to focus on her face and I guess I do a bit of "lip reading"...
Ya can get around it... I think I have....
