29、Peter liked music very much when he was at school, but when he went to the university, he decided to study medicine instead. After he passed the examinations and became a doctor, he had to work in a hospital for some time. There he discovered that a lot of patients were happier and less worried about their illnesses if they could hear pleasant music. When Peter became a surgeon and began to work for himself, he decided to keep his patients happy by having a tape recorder in his waiting room, playing beautiful music for them.
But soon after the tape recorder was put in the waiting room, Peter's nurse heard a woman who was sitting in the crowded waiting room one morning complain, "Here we're all waiting to see the doctor, and he's just playing the piano in his office instead of doing his work!"
