How do you know when you're getting old?

You sink your teeth in a steak and they stay.
You have too much room in your house and not enough medicine cabinet.
You get your exercise going to funerals for your friends who exercised.
The little gray headed lady you helped across the street is your wife.
Your pacemaker makes the garage door go up when you watch the girls go by.
A fortune teller offers to read your face.
Your back goes out more often than you do.
You burn the midnight oil after 9 pm.
The best part of your day is over when the alarm clock goes off.
