Have you heard the story about the elderly gentleman who had suffered from a serious hearing problem for a number of years? He went to the doctor and was fitted with a set of hearing aids that gave back his hearing completely - 100%
The gentleman went back to the doctor a month later. The doctor ran some tests and declared, "Your hearing is perfect. Your family must be really pleased that you can hear again."
The gentleman replied, "Oh, I haven't told my family yet. I just sit around and listen to their conversations. I've changed my will three times!"
