请帮我看看有没有语法错误.

The story is about a man 【who】 went to see a doctor. He was afraid that he 【had been】 ill. Because he was very tired all day, 【ate little】, 【and】couldn't 【fall asleep】. But the doctor told him 【that】 he was nothing wrong. He was working too hard and worried too much, and he hadn't enough time to 【take】 an exercise. Then the man asked the doctor 【for】 some medicine to help him to sleep. But the doctor 【didn't give】 him any medicine, 【instead】 he gave him an advice: Don't worry, take some exercises. If he had lost his hard job, he would have found an easier one. 【这句话我不明白你的意思……是说“他应该放弃现在这个困难的工作换一个轻松的”吗？这样的话是He had to give up his present difficult job and find an easier one.】Because health is much 【more】 important than wealth. The man agreed with the doctor's advice.
