Hello Terence, Let me clarify the last sentence you disagree on. Yes i'm certain the factors of life influence the effects of a product. Et al the goal of medicine or helpful equipement is to make the symptoms go away or cure. So the goal is to make people happier in there life. Medicine can work, or wont. Even when cleared by all rules en regulations etc it can fail its duty. A graph or report cant change someones life or cure a decease. Its the combination of factors that make it work. Its more or less the grey area that i was referring to. My statement was not to discuss the proof or lack of proof regarding the effects of Valkee. I was wondering, what is your background or link with science? You seem passionate about the subject.
