A businessman had been working too hard.He found that he could not sleep at night,but kept on falling asleep during the day.He became so worried that he went to see his doctor.
"Can you help me,doctor?" he asked."I used to sleep so well,but recently I haven't been having more than two hours a night."
The doctor examined him carefully,gave him some tests,told him to work less hard,and take different kinds of medicine to help him.He said he was sure that he was not seriously ill,and that he would soon be better.
But the business grew worse instead of better.He slept even less than before at night,and fell asleep in his office.He went to see the doctor more often,and it took the doctor a long time to find out the reason; the businessman's servant was giving him the sleeping medicine in the morning,and the ones to keep him awake at night!
