Age matters?

I'm not this old but it's still funny!
Have you ever been guilty of looking at others your own age and thinking, surely I can't look that old?" Well... You'll love this one!
I was sitting in the waiting room for my first appointment with a new dentist. I noticed his DDS diploma, which bore his full name. Suddenly, I remembered a tall, handsome, dark-haired boy with the same name had been in my high school class some 40-odd years ago. Could he be the same guy that I had a secret crush on, way back then?Upon seeing him, however, i quickly discarded any such thought. This balding, gray-haired man with the deeply lined face was way too old to have been my classmate. Hmmm ...or could he? After he examined my teeth, I asked him if he had attended Morgan Park high school "yes. Yes, I did. I'm a mustang," he gleamed with pride."When did you graduate?" I asked. He answered, "in 1959. Why do you ask?""You were in my class!" I exclaimedHe looked at me closely.
Then, that ugly, old, wrinkled son-of-a-bitch asked,"what did you teach?"
