I lost most high frequencies in one blast of the howitzer at ROTC summer camp, 1969. The whistling (tinitis) has finally stopped, but the factory tests in 2008 showed I am 10 db down at 14 khz and have nothing above that.
I still thoroughly enjoy music. But I take the occasional ear infection very seriously. My grandmother was mostly deaf, due to a "bad cold" in 1905. She had damaged stirrups in her ears.
With a lot of retina deterioration in my father's family due to diabetes, I'm memorizing pieces on the piano as hard as I can go. I tested diabetic three years ago. I could deal with bad eyesight; I ride the bus a lot now to accomplish errands, just due to the price of fuel and vehicles. But no music, no radio, nothing played by me- that would be very boring.
