“Early to bed, early to rise” makes people healthy, wealthy and wise. This is an old English saying.Children should have ten hours’ sleep everynight, or they can’t do their work very well. They will not be wise nor healthy. The body needs exercises. Walking, running, swimming and playing ball games are all exercises. Exercises keep the body strong.
