Maybe it's true that life begins at fifty. But everything else starts to wear out, fall out, or spread out. There are three signs of old age. The first is your loss of memory, the other two I forget.

Middle age is when work is a lot less fun and fun a lot more work.
Statistics show that at the age of seventy, there are five women to every man. You know you're getting on in years when the women at the office start confiding in you. Middle age is when it takes longer to rest than to get tired. By the time a man is wise enough to watch his step, he's too old to go anywhere. Middle age is when you have stopped growing at both ends, and have begun to grow in the middle.
