Gather around, youthfully oriented beings and hear a truthful tale of mystery and discovery. Once upon a time, in the twentieth century, there was a curious and clever dentist. There had to be a reason why some less civilized tribes anthropologists call primitive or backward, had the best teeth this side of heaven. The dentist just had to know why. He began to travel the world, since he had somehow gotten rich enough to do so.
He cultivated the friendship of these various odd and interesting cultures on many different continents to the extent that they would let him take pictures of them pulling their cheeks away from their glistening teeth to better show them all to his magic picture box. It was most amazing that none of them required orthodonture of any kind. And yet, apparently the only advantage that these people had in life was that they did not live like modern, civilized, normal people with knowledge obviously unparalleled in history.
Then this clever fellow began looking at the people whose parents had left the tribe and thus led a civilized life, just like us normal people. What do you suppose he found? That's right! These civilized natives now were getting cavities and deformed, overcrowded upper dental arches just like us with crooked teeth, joining the rest of us in our mandibular misery,
As he homed in on the activator whose deficiency was causing all of us advanced modern folks such a problem (and the generation of billions in profits for specialized dentists), he decided to name it. It was still quite a mystery to him so he named it "X." This name consigned the discovery to obscurity for a generation or so.
But it turns out, all this was not just of importance to dentistry. Now word is beginning to spread that this same substance is pivotal in making our whole skeleton stronger. Not only that, it will clean up the plaques of our hardening arteries, clearing the cholesterol/calcium amalgams and delivering that misplaced calcium to our bones, where it is desperately needed, from the arterial walls where it has been killing us in droves. VITAMIN K-2.
(Oh, by the way. Vitamin A had nothing to do with any of this.) I didn't count the dozens of times it appeared in the posts of the thread.
Even true tales need to end. I choose this: ...and the wise, and the clever, and the true, and the good lived happily ever after.
