An agitated patient was stomping around the psychiatrist's
office, running his hands through his hair, almost in tears.

"Doctor, my memory's gone. Gone! I can't remember my wife's
name. Can't remember my children's names. Can't remember
what kind of car I drive. Can't remember where I work. It was all
I could do to find my way here."

"Calm down. How long have you been like this?"

"Like what?"
