4. Let's eavesdrop on a brief conversation between Dr. Know and Mr. Hypochondrius:
Samuel: "Well, Doc, I asked you a question. How bad is it?"
Doc: "Oh, it's not bad at all. In fact, it's quite good. You have no body temperature, and your blood pressure is normal. Your respiration and heartbeat are normal. You don't have any infections. Your ears, nasal passages, and throat are clear."
Samuel: "Doc, what about the chronic pain in my back and sides? What about seven sleepless nights in a row? What's up with that, Doc?"
Doc: "What about that? That, Mr. Hypochondrius, is psychosomatic."
Samuel: "Doc, you mean to tell me I'm only sick in my mind?"
Doc: "That is my professional opinion, Mr. Hypochondrius. There's nothing physically wrong with you except for these ailments you have created for yourself. Your pains are imaginary. Your inability to sleep is due to nerves, nothing more. In short, Mr. Hypochondrius, you're a very healthy man."
