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 75, 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 75 and expected to live to be 100, and the newspaperman asked him how he managed to be healthy at 75. 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 75 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.
