"Will somebody answer that damn phone?!?!"
Seriously, that's got to suck. I've damaged my hearing enough I wonder if I'll get it (shooting without ear protection, loud music, power equipment and straight pipes), but my parents don't seem to have it despite damaging theirs for years.
My dad has better hearing than I do after a lifetime of hard rock concerts, industrial/construction work, and gun shots. His friend that's the same age has pretty bad hearing.
My mom can't hear for crap though, but I don't think she has the ringing.
