Age is Just a Number

Age is just a number that helps you count down until your death, which is why people drink so much on birthdays.  You don't have to stop doing things just based on age, but when your skin gets really wrinkly, you need to stop the tube tops and when you lose bladder control, no more leather seats. 

The older you get, the more likely you are to forget your age, which is good news as it makes the countdown seem less imminent.
