For what it's worth: Topics like this never cease to amaze me. For example, it wasn't all that many years ago that the medical establishment regarded iris analysis as hocus-pocus. Laureen and I were educated and certified in iridology in the mid-1980s, when the medical profession still considered iridology as quackery--even though iris analyses were far more accurate overall, percentage-wise, than medical doctors' diagnoses. As usual, when the medical profession realizes that a technique used for decades by non-allopathic practitioners actually is valid, it becomes their discovery. Don't get me wrong; I'm delighted to see them wake up every now an then--even if it takes some revolutionary new technology to facilitate the awakening. Thanks for listening.
