"Improvement" don't mean nothing in this context. It was mostly due to the nutritional supplements. I feel like I'm having to restate the obvious so you can reply to this and have the last word, I don't care. Anyone who reads this whole thread, and has half a brain, can see the clear point I've made. The study proved that the Clark Zapper does not kill microbes otherwise there would of been more than improvements, but rather cures.
Clark has always relied on the 555 integrated circuit which cannot output a negative voltage because it is only supplied a positive voltage. So her zappers have always been positive offset.
