What does the doctor suggest the man should do?

W: Well, there is not too much you can do about the flu, you know. The best thing you can do is to stay home. It’ s best to stay away from other people, so why don’ t you take a couple of days off from work?
M: Yes, I will. And do you think I should stay in bed and rest?
W: It’s not really necessary to go to bed. Just as long as you stay indoors and rest. You know, watch TV or read.
M: I see. Nothing too active, huh? And is it a good idea to drink a lot?
W: Yes, you need to drink lots of liquids. That’ ll help. Now you won’ t feel very hungry, but when you do eat, just eat a little. Don’ t have a big meal. That way it’ ll be easier to rest.
M: OK. Are you going to give me a prescription?
W: No, I’ m afraid there is really no medicine for the flu. You just have to rest and wait for it to go away. Medicine won’ t really do any good.
