What’s the man’s trouble?

W: Well, there’s nothing very much wrong with you, I’m glad to say. You’re working too hard and worrying too much. Do you often take exercise?
M: No, doctor. I never have time for exercise. I go to work very early in the morning and come back very late. Then I can’t go to sleep. Can you give me some medicine to help me to sleep?
W: I can, but I’m not going to, You don’t need medicine. You need advice. Don’t work so hard, because too much work is bad for you. And it’s no use worrying about your work. Take exercise every day.
M: But I may lose my job, doctor! It’s hard to get a job like mine.
W: Then find an easier one, even if you can make less money. Which do you think is more important, health or wealth?
