Today learning the simple exercise for saving sight called swinging. Stand with your feet 12 inches apart, hands held loosely at the sides, the whole body and mind relaxed. Gently sway your body from side to side, slowly, steadily, with the heels rising alternatively but not the rest of the foot. Imagine you are the pendulum of the clock, and move just as slowly. Swinging should be done in front of a window or a picture. You will see the object moving in the opposite direction of your swing. This must be noted and encouraged. When you face one end of the window or object, blink once. This exercise has a very beneficial effect on the eyes and the nervous system.
