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. You're getting old when you don't care where your spouse goes, just as long as you don't have to go along. Middle age is when work is a lot less fun and fun a lot more work.
Statistics show that at age of seventy, there are five women to every man.
You know you're getting on in years when the women in 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. A man has reached middle age when he is cautioned to slow down by his doctor instead of by the police.
