I believe people here have no doubt on your good intention to ex

and trying to remind us the side effects of the gypsum, we do appreciate your concern, but maybe some more solid proof or evidence will support your opinion better.

So far as I can see, first of all, no offense, below is just my 2 cents and nothing personal: the statements and evidence you listed in this article like ancient fiction characters were taller than us modern people; or compare to certain races, Chinese people have less teeth... all these statements have no directly notation on resources and make your point looks more like a hoax other than a scientific advice. I think that's part of the reason so many people disagree with you and wanted to post against your opinion.

thanks
