Ok, I'm 54 and I can't see or hear as good as I use to either. This is funny for those who have a hard time hearing (like me) and this kind of thing happens to me all the time:
This old guy was talking to his neighbor telling him about the new hearing aid he just got. He said, "It cost a fortune, but it was worth it. It works perfectly!"
"Really," said the neighbor. "What kind is it?"
He answered, "Ten thirty."
