There are three signs of old age. The first is your loss of memory. You forget the other two.
When you don't care where your spouse goes, just as long as you don't have to go along.
When work is a lot less fun - and fun is a lot more work.
When the girls at the office start confiding in you.
When it takes longer to rest than to get tired.
When you have stopped growing at both ends, and have begun to grow in the middle.
When you realize that caution is the only thing you care to exercise.
When you wake up with that morning-after feeling, and you didn't do anything the night before!
When you lean over to pick something up off the floor, you ask yourself if there is anything else you need to do while you are down there.
