An elderly gentleman has had serious hearing problems for a good number of years now. Finally, he went to the doctor and the doctor fitted the man with a set of hearing aid that allowed him to hear as well as before.
After a month, the elderly gentleman visited the doctor for a follow-up. The doctor checked him and said with a beam: "Your hearing is perfect. Your family must be really pleased that you can hear again."
The gentleman replied casually: "Oh, I haven't told any of my family yet."
"And why not," enquired the doctor.
"I prefer to just sit around and listen to the conversations around me," the old gentleman said with a wry smile. "You know, I've changed my Will three times already!"
