Just you not understand.
oxygen is source of energy.
there is more oxygen in stomach and intestines than your lungs.
that zone is stupid chinese calls dan tian.
Clever people has no names for it. because they cannot locate the energy source.
same as clever people call atmosphere air and vacuum space. Just because they cannot live in space, its no meaning to them.
but i think clever also cannot live in water. Clever have monopoly on witchcraft.

By the way you get and store energy in your digestive system, not your lungs.
Otherwise you only need breath, no need eat and make shit.
energy is produced when oxygen meets fats. But i not sure, because the smart kids confused me about have good fats and bad fats.
The always confuse people about the good hats and bad hats. Its just all hats.
Same like have good girls and bad girls.
A good girl is a girl thats escape being caught bad.
