Hearing is good or bad?

An elderly gentleman had serious hearing problems
for a number of years.

He went to the doctor and the doctor was able to
have him fitted for a set of hearing aids that
allowed the gentleman to hear 100%.

The elderly gentleman went back in a month to the
doctor and the doctor said,

"Your hearing is perfect. Your family must
be really pleased that you can hear again."

To which the gentleman said,

"Oh, I haven't told my family yet. I just
sit around and listen to the conversations.
I've changed my Will three times!"
