I had never heard of it until last year and my brother who is two years younger (65) asked me if I have tinitus. WTF is that? He told me -- and I listened -- and what do you know? I have it. Now I can't get rid of it. The trouble is that it drowns out high pitched real sounds like my dog wining and some of my wife's speech. It gets me in trouble because they both accuse me of ignoring them
