@Merry Andrew,
Quote:Could you kindly -- once and for all -- explain the difference between a 'rule' and a 'prescription'? I don't get it.
Okay, Merry.
You do know that the kidneys process the air we breath. They separate the O2 from the other gases present in air and attach it to microscopic kidney stones; not to be confused with those big ones that hurt like the dickens.
A moment, autonomic response coming in, ... "Avoid cliches". [note to self: someday, I'm going to have to find out what that means.]
These tiny stones are pushed thru a tubular system that parallels the arteries and veins, which are reserved for fun things like alcohol and drugs. Waste gases are passed thru the urine tho' occasionally some leaks, which causes those embarrassing moments.
As these little stones run throughout the body, they are able to detect places where O2 is needed. They stop briefly while osmosis sucks the O2 off the little stones. Being depleted of O2 causes their transmission to flip into reverse which sends them - some commentators feel "headlong" back to the kidneys is correct but to be more precise, [precision is essential if we are ever to survive as a race] because they are in reverse, they go "taillong" back to the kidneys to be replenished with oxygen. [I should take this opportunity to advise the reader not to use abrevs like O2; the careful writer uses complete words]
