A smile costs nothing, but gives much. It reaches those who receive without making poorer those who give. It takes only a moment, but the memory sometimes lasts a lifetime. No one is so rich or mighty that he or she can get along without it, and no one is so poor that he or she cannot be made richer by it. A smile creates happiness in the home, fosters goodwill in business and is the countersign of friendship. It brings rest to the weary and cheer to the discouraged. A smile is sunshine to the sad and is nature's best antidote for trouble. Smile and humor are infectious. The sound of roaring laughter is far more contagious than any cough, sniffle, or sneeze. When laughter is shared, it binds people together and increases happiness and intimacy. Laughter also triggers healthy physical changes in the body. Humor and laughter strengthen your immune system, boost your energy, diminish pain, and protect you from the damaging effects of stress. Best of all, this priceless medicine is fun, free, and easy to use. Laughter, indeed, is a powerful antidote to stress, pain, and conflict. Nothing works faster or more dependably to bring your mind and body back into balance than a good laugh. Humor lightens your burdens, inspires hopes, connects you to others, and keeps you grounded, focused, and alert.
