Deep breathing, walking:
Lungs and Lymph Glands

Hiking, swimming, bending, twisting all help lungs to breathe. Quick inhalation, slow exhalation helps the lung structure.
The following DEEP BREATHING EXERCISES should be practiced faithfully each day before an open window. Breathe in through the nose, exhale through the mouth (in a blowing effect). Early morning is the best time, before traffic puts poisons in the air or late at night if one gets up during the night for some reason. Remember to breathe deeply, and exhale ALL THE WAY, forcing old stale air out.

(ONE CAUTION: Fresh air can make one light-headed or faint – go easy at first.)
Repeat until comfortable. Practice good posture also throughout the day, whether sitting or standing. Walk briskly each day, walking two miles minimum, as you are able, breathing deeply while walking.
Lymph fluid can be moved to carry out waste only in this way (except by massage, which is more expensive; all you spend on the above exercises is time).
An excellent exercise is “bouncing” on the trampoline. It is good for everyone, but almost essential for those suffering from severe heart stress, cancer or other severely enervating afflictions.
Everyone should sing loudly (if not well) daily. Playing a harmonica is an excellent deep breathing exercise.
