"All work and no play makes Jack a dull boy" is a popular saying in the United States. Other countries have similar sayings. It is true that all of us need recreation. We cannot work all the time if we want to maintain good health and enjoy life.
    Everyone has his own way of relaxing. Perhaps the most popular way is to participate in sports. There are team sports such as baseball, basketball and football. There are individual sports such as golf and swimming. In addition, hiking, fishing, skiing and mountain climbing have a great attraction to people who like to be outdoors.
    Not everyone who enjoys sporting events likes to participate in them. Many people prefer to be spectators, either by attending the game in person, watching them on television, or listening to them on the radio. When there is an important baseball game or boxing match it is almost impossible to get tickets; everybody wants to attend. Chess, card-playing and dancing are forms of indoors recreation enjoyed by many people.
    It doesn’t mater whether we play a fast game of table-tennis, or go walking through the woods on a brisk autumn day. It is important for everyone to relax from time to time and enjoy some form of recreation.
