I've had it since I can remember. The only thing I can figure is it is because I had bad ear infections when I was young. Working in industry with no hearing protection didn't help.
I had a boss for 8 years who would ridicule you for wearing hearing protection while doing things like grinding. He did the same when you wore a respirator while spraying paint. He actually forbade me to wear ear protection because he said I couldn't hear him.
I chit you not!! That was the early 80's when you did all you could to hang on to a job.
Last I saw him he had hearing aids in both ears and looks like he's 75, and he's only two years older than me.
Being an azzhole and paying the price.
