You are right, that needs to be added to my article. The article was written, as are most of my articles, with the idea of submission to Natural News. Unfortunately they have a strict guideline these days of limiting articles to 600 words and the one I did above was totally maxed out. I have to really struggle with almost every article I write for NN to keep it to 600 words or less. I have a hard time sometimes saying hello and good-bye in only 600 words!
In my opinion the rule is a nutty one to apply universally and arbitrarily, especially for someone who likes to go in-depth in their articles. Time and again, readers comment on my articles to the effect that "You should have included . . ." or "I can't believe he left out . . ."
Sigh . . . nothing lil ol me can do about it, and I depend greatly on the bit of money those articles make me.
