Losing hearing and vision is one of my fears when it comes to aging. I get headaches and once thought it was time for glasses, when I went to get checked out, I was told that my vision was amazing still (which I kind of knew). At work, My hearing is tested annually and it hasn’t changed in ten years, which I’m surprised to see since I ride motorcycles, work in a really loud environment(earplugs are mandatory) and always have headophones at home while listening to music and playing this contraption of a “drum” called tambora. My car also has a 3000 watts sound system. I really hope It stays like this for many years, but I’m only 31 (32 next month) now, so I also still have my hair too.
Hope you can get the right equipment for the job and that your hearing doesn’t get any worse for a while.
