Not many years ago， a wealthy and rather strange old man named Johnson lived alone in a village in the south of England. He had made a lot of money in trading with foreign countries. When he was seventy-five， he gave ￡ 12，000 to the village school to buy land and equipment for a children‘s playground.
As a result of his kindness， many people came to visit him. Among them was a newspaperman. During their talk， Johnson remarked that he was seventy-five and expected to live to be a hundred. The newspaperman asked him how he managed to be healthy at seventy—five. Johnson had a sense of humor. He liked whisky and drank some each day. ;I have an injection 注射） in my neck each evening.;he told the newspaperman， thinking of his evening glass of whisky.
The newspaperman did not understand what Johnson meant. In his newspaper he reported that Johnson was seventy-five and had a daily injection in his neck. Within a week Johnson received thousands of letters from all over Britain， asking him for the secret of his daily injection.
