We all regard recreation as part of our life, for it is impossible to keep in good health unless we take sufficient relaxation. The mind, too, requires change to make it acute and vigorous. There is much truth in the old proverb, "All work and no play makes Jack a dull boy." Of course, everyone should relax according to his own circumstances. People who sit a lot at work should choose a kind of recreation that will exercise their muscles. Some examples are: football, tennis, kite-flying, boating, cycling and dancing. Those who spend most of their time in the open air and constantly employ their muscles should adopt reading or some other quiet form of recreation. However, some young men spend their leisure hours indulging themselves in gambling, drinking or other bad activities. Improper means of killing time not only waste valuable time but also do great harm to the person concerned.
