I must go for a re-test. When my late wife was nagging me about my hearing (I seemed to have acquired a mental "filter" button) let's see, about 10 year ago so I was 52, the hospital said my hearing was normal, and I asked "do you mean "normal for my age" and they replied "no, normal".

I do however sometimes have a slight whistle in my right ear (usually presages an infection) and spent most of my life abusing my hearing.
