k. My wife finally persuaded me to visit you to find out what the trouble is.

W: From what is written here I can see that you have a very bad cold three years ago and that you also had a small operation last year. Did you have any bad effect after that？

M: Well, I don't remember.

W: For example, how long did you stay at home each time you are ill？

M: Just a couple of days, but about six months ago I was home for about two weeks with a cold for cold or something.

W: Did you see a doctor at that time, or did you just stay at home？

M: No, I didn't see a doctor. When I began to feel better, I returned to work.

W: And when did you start feeling so tired again？

M: It must have been about ten days ago. When I came home from work one night, there just didn't seem to be any reason to go back the next day.

W: Well, it sounds as if your problem may be the kind of work you do. The test ! just made doesn't show anything really wrong. But I would like to make some further tests in the hospital.

M: That's fine with me.

W: All right, you can check tonight and I'll make the tests tomorrow morning.
