I hope she realizes the damage she's doing to her hearing.

I,too, used to listen to my music very loud.
I also worked for 2 1/2 years in a place of business where LOUD was the order of the day. We had an ice cream machine that was extremely loud, 2 slush machines that were louder than the ice cream machine and customers who shouted.
I am discovering now that my hearing is almost completely shot. I have to turn things up or (if DH isn't home)turn on the captions when I'm watching TV because I can't understand what they are saying.

I hate the thought of it, but probably within the next six months or so, I'm going to see an audiologist and get a hearing aid. I am too young for this...
