This is an excellent article.  Gotta read the whole thing, and if you're not gonna read the whole thing (I'm asking for your committment to read all of it!) please don't even bother to open it.  This is the kind of information people refuse to believe until they're in the midst of some crisis caused by this stuff. If you're only going to read half the article and not finish it for the explanations that abound, you'll learn nothing and be able to pass on nothing.
