Mr. Gregory Gale is one of the few people in England who are 100 years old. On the day of his birthday, he played a game of tennis and went for a long walk. A few days later a radio reporter came to his house and asked him if he had any “secrets of long life”. This is what Mr. Gale said, “No, I don’t know any secrets like that, but there are a few simple rules of good life. I’ve always kept them all my life. The first is this: Don’t listen to those fools who tell you to give up all the pleasures of life! The second is to enjoy all the pleasures of life in moderation(节制). For example, I’ve always smoked a few good cigars every day. Not many, mind you! Only two or three! I’ve always also drunk a little good wine with my meals, perhaps two or three glasses.
