Kelder described these techniques in a slim booklet titled The Eye of Revelation, published in 1939.

mastery of fire and processing food, an enormous brain, and the ability to communicate in a vast range of sounds—would obstruct our mouths and throats and make it much harder for us to breathe. This recessed growth would, much later, make us prone to choke on our own bodies when we slept: to snore.*

To understand how and why Douillard’s experiment worked, we first need to understand the ways the body makes energy from air and food. There are two options: with oxygen, a process known as aerobic respiration, and without it, which is called anaerobic respiration.

Their transformation was a matter of training; they’d coaxed their lungs to work harder, to tap the pulmonary capabilities that the rest of us ignore. They

I looked for some kind of verification of these claims in more recent research in pulmonology, the medical discipline that deals with the lungs and the respiratory tract, but found next to nothing. According to what I did find, breathing technique wasn’t important. Many doctors, researchers, and scientists I interviewed confirmed this position. Twe

But larger lungs equaled longer lives. Our ability to breathe full breaths was, according to the researchers, “literally a measure of living capacity.”

How we breathe really matters.
