There are few persons whose health and personal appearance would not be improved costly if they would take several meals of fresh air consisting of 20 to 50 deep inspirations in a park, or some other place, where the air is pure and bracing. Slowly inhale as much as you can get into the lungs without discomfort (avoiding a strain), and then exhale again just as slowly.
