Long ago, a young man often said that he was very poor and had nothing. One day, an old man walked past. He heard the young man's words and said, "Hello, young man! What are you talking about? You have nothing? That's not true! You have the most expensive things in the world, so you are a rich person." The young man was very surprised and asked, "Why do you say that? You can see I have nothing. What are these expensive things?" Then the old man said, "If you sell your eyes to a rich blind(盲的) man, you'll make a lot of money and can get everything you want. Would you like to sell them?" The young man didn't want to be blind, so he said, "No." The old man asked again, "Then what about selling your hands for some gold(金子)?" The your and shook his head for the second time. At last, the old man said, "Now you understand. You have the most expensive things in the world." So the old man taught both the young man and us a lesson—-health is the most important for us.
