Huh???
When I was younger, one of my first jobs was working in a jewelry shop. I used to clean every piece of jewelry using the VERY loud steamer. I swear that as a result of that, I've had hearing loss, in addition to listening to my Walkman too loud and playing music above the acceptable level in my car. 
Well, a study by University of Michigan Kresge Hearing Research Institute reveals that I am not alone. About 10 million people in the United States suffer from noise-induced hearing loss. While they haven't found a way to reverse hearing loss, the researchers have come up with a vitamin cocktail to take before being exposed to loud noises (i.e. our troops) in an effort to prevent some of the noise-induced damage. The U-M researchers discovered that this new combination of vitamins, (A, C and E) when mixed with magnesium, can prevent noise-induced damage to the ears by blocking some of these complex cellular reactions. Their studies show that it blocked about 80% of the damage. This is a great discovery for those whose jobs or hobbies involved high volume situations. I wish I had known about this combo back in the day!
