Modern scientific research shows that laughter can promote physical and mental health. A smile, it seems to be laughing is a continuous mouth breathing action. Laughing, the body’s carbon dioxide gas exhaled at a speed of 100 kilometers per hour, at the same time, the body reflex inhaled more oxygen.
