Dear Richard I can understand your line of thinking. But I also at one time thought along the same lines. However things have since convinced me differently. The tiniest bit of Mercury in your system is EXTREMELY poisonous to you if you have a sensitivity to it. A vega test will not tell you this but a Melissa test will. Also I have since heard such horrific stories of Mercury poisoning that I dont doubt eventually the majority of the population will be effected by it. I just heard from a friend of a guy contracting tongue and jaw cancer after having his Mercury fillings removed. He never had a problem before. Coincidence maybe. I agree fully with you that we do abuse our bodies from quite an early age these days and the food and atmosphere are full of all sorts of crap. But its strange how I for one, hands up, lived the life of smoking and drinking and felt really healthy. Would swim 50 lengths a morning, work full time, clean the house, do the shopping, cook the food, and brought up 3 kids almost single handedly. Two trips to the dentist and the most bizarre symptoms within a day, too much of a coincidence I think. I know what your trying to say, but I have medical proof that Mercury caused my illness, my immune system to stop working and for me to get Epstein Barr virus and Cytomeglavirus. My doctor has just prescribed me Quinine for leg cramps. I was a bit sceptical, just looked it up. It is a dangerous poison, says musnt be used for leg cramps and can cause kidney damage. Follow your heart. You are an intelligent person, the smallest amount of any poisonest substance can wreak havoc on anyone. Mercury is no different. Best of luck AND Best wishes Tracy x
