From what I have learned about chlorine dioxide thus far, I would tend to agree with you. It is not a natural substance, and really there is nothing "mineral" about it.
As far as doctors go, they are necessary only in the most life threatening situations (my opinion). I have nothing against any doctors personally, I think the majority of them are good people that became doctors to try to help people, but unfortunately the medical industry does not train them properly. Doctors receive minimal (if any) training in nutrition. They are instead trained to diagnose and treat symptoms by prescribing medications. What is the effect? Sure people are living longer, but they are also much less healthy and happy. So we end up with a bunch of people living long lives, but suffering with multiple ailments. For me personally, I'd rather live as a happy healthy individual, free of the poisons offered by pharmaceutical companies and mainstream western culture, even if this did mean that I didn't live as long. This is my own personal choice for the way I want to live my life, the important thing is to realize that we all do have a choice as to how we want to live.
