Only a certain number of years

As you grow older time seems to go faster. You realize that you will only be around for a certain number of years and you wish you could slow down time so that you can enjoy your time for as long as you can making every second count. When you are very young you can't wait to be a teenager. When you are a teen you can't wait to be an adult. As an adult you realize how much easier life was when you were young. When you get into middle age you panic and send yourself into mid life crises. When you get even older you enjoy every moment when you can while you can.
