An aging patient was stomping around his 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?"
