In my computer there are different documents. One of them is "Original thoughts and observations" with more than a dozen pages. Years ago I recorded a thought, "Hearing is for other people. Seeing is for ourselves." A couple months ago someone fired a magnum rifle very close to me when I was not ready with inserted earplugs and earmuffs. Instantly I knew my hearing was shot. It is like I'm in the shower and have soap in my ears all the time.
What used to me a theory has been verified in my own experience now.
