Patient:  Hello doctor! Can you spare me a few minutes?

Doctor: Certainly! Come in and sit down. Now, what is the matter with you?

P: That is just what I want you to tell me.

D: Well, tell me how you are suffering?

P: I seem to be generally out of sorts. I feel no hunger for my food, and yet I am always suffering from stomachache.

D: Are you troubled with headaches?

P: Yes, I am. And what is worse I cannot sleep at night.

D: I see, what is your work?

P: I am a clerk in an office, and have to work long hours.

D: What sort of exercise do you take in the evening?

P:  I don't take any exercise. I feel too tired to exercise when I get home that I simply want to sit down, or go to bed.

D: I see. Well, you are evidently run down, and need a rest and change. All your troubles are signs of nervous exhaustion. I will give you a nerve tonic but the main thing is rest. If you do as I say, you will soon be all right.

P: Thank you, doctor. I will follow your advice, Good night!

D: Good night! And follow my advice correctly, and come back in next week if the problem remains.
