Leonardo da Vinci was born on April 15, 1452 in Italy. He is best known as an artist today. One of his famous paintings is called Mona Lisa. However, Leonardo had many other natural abilities. He was also a great inventor. Many of his inventions have become important in modern daily life.

Although Leonardo hated war, he invented many different machines used for war. His most special invention was the machine gun, which was produced and used in war many years later.

    By watching the way birds fly, Leonardo tried to find out the secret of flying. Among his sketch (素描) we can see several objects. We consider them as modern flying machines.

    Leonardo spent many hours thinking about how to make good use of time. He developed ideas for labor-saving machines like cutting machines.

Leonardo was a strange man. He didn't eat any meat, which was very unusual in those times. He never published(发表) his ideas and scientific discoveries. He usually used mirror writing, which looks like writing in a mirror, starting from the right side of the page and moving to the left.

    We have very little of his work today. Leonardo finished only a few of his paintings. He left many unfinished because he thought they were not perfect. No one in his life time knew how great Leonardo was. We now believe, however, that he was one of the cleverest men the world has ever known.

    An English traveler found himself in Norway（挪威） with only enough money to buy the ticket for his journey back home. As he knew that it would take him only two days to get to England, he decided that he could easily spend the time without food. So he bought a ticket and went aboard the ship. The man closed his ears in order not to hear the sound of the lunch bell. When dinner time came , he didn't go to the dining room, saying that he was not feeling very well.

    The next morning he still didn't have breakfast and at lunchtime he again stayed in his room.But at dinner time he was so hungry that he went to the dining room and ate everything the waiter put in front of him. He got ready for a quarrel.

    "Bring me the bill," he said. "The bill, sir?" said the waiter in surprise. "There isn't any bill. On our ship meals are included in the money for the ticket," said the waiter.

    Studies have shown it takes a doctor about 18 seconds to stop a patient after he begins talking.

    It was Sunday. I had one last patient to see. I came close to her room in a hurry and stood at the doorway. She was an older woman, sitting at the edge of the bed, trying to put socks on her swollen feet. I spoke quickly to the nurse, saw her chart saying she was in stable condition. I was almost in the clear.

    She asked if I could help put on her socks. Instead, I began a long speech that went something like this: "How are you feeling? Your blood sugar and blood pressure were high but they're better today. The nurse said you can't wait to see your son who's visiting you today. It's nice to have family visit from far away. I'm sure you really look forward to seeing him."

    She stopped me with a serious voice. "Sit down, doctor. This is my story, not your story."

    I was surprised and ashamed. I sat down. I helped her with the socks. She began to tell me that her only son lived around the corner from her, but she had not seen him in five years. She believed that the pressure of this caused greatly to her health problems. After hearing her story and putting on her socks, I asked if there was anything else I could do for her. She shook her head and smiled. All she wanted me to do was to listen.

    Listening to someone's story costs less than expensive diagnostic testing but is key to healing. I often thought of what that woman taught me—the importance of stopping, sitting down and truly listening. And, not long after, unexpectedly, I became the patient, with a diagnosis of sclerosis at age 31. Now, 20 years later, I sit all the time—in a wheelchair.

    For as long as I could, I continued to see patients from my chair, but I had to give up my job when my hands were influenced. I still teach medical students and other health care professionals, but now from the view of doctor and patient.

    I tell them I believe in the power of listening. I tell them I know firsthand that huge healing takes place within me when someone stops, sits down and listens to my story.
