You know, when you think about it - "they" say that we don't have them, now that we should not get rid of them (so which one is it: either we don't have them and there's nothing to get rid of, or we do have them...?), and that they are now actually good for you... leads me to believe that either those "experts" who are behind it all are either incredibly stupid (not impossible) or are part of a well thought up Conspiracy (or both?).
Morgellons was created to dumb people down through adrenal exhaustion and so on. It is quite possible that lack of awareness about dangers of parasites has exact same goal, except that those who follow the official line are not aware of being part of that conspiracy.
