Another reason for ear plugs/muffs!
For my age (69) I'm in pretty good health, only problem worth mentioning is mild neuropathy in my feet. A few weeks ago I began to experience some dizziness, and those spells got worse, to the point that I fell a couple of times. After the second fall, my wife insisted on driving me to the doctor. To shorten a long story, my problem was diagnosed as pressure on some nerve in my ear caused by wax buildup -- the dr flushed out a pretty big chunk(!). After some Q&A, the dr said working in a high dust environment could cause more and firmer wax buildup, so another reason to wear plugs or muffs. Like many here, I've always preferred muffs, but only wore them when loud machinery was running.
