How We Live On Air
Air is the substance on which principally we feed. What we eat is of secondary importance. The purity of the blood and the strength of the arteries through which it throbs depend absolutely upon right breathing. The greater the quantity of air taken into the lungs, the more oxygen for the purification of the blood—the constant and prime requirement for health.
The system of breathing which I advocate in this work is not a mere matter of theory, something vague and experimental. It is concrete; it is exact; its worth has been definitely proved. I have demonstrated the merit of the exercises in my own case. During a year and a half of practice my chest measurement increased from thirty-eight inches to forty-two.
