The person who challenged the medical profession was also a Doctor of Medicine.
But why suffer the inconvenience and misery of a cold when you do not have to?
This only shows that your body (like many others) is toxemic, and therefore subject to colds and other maladies.
Colds have nothing to do with viruses except that the person suffering from one has the metabolic environment to support it; if not, then you will never ever experience one.
Regular colds are a safety valve initiated by your body to throw off excess/surplus toxins, but does not eliminate toxemia altogether.
Any virus, including HIV, can only take hold if the environment of the body allows it to; if you are free of toxemia, have a strong immune system from diet/supplementation, and a strong body thru exercise, coupled with judicious sunbathing, and receive adequate rest and sleep, there is no threat at all from ANY disease............ http://www.soilandhealth.org/02/0201hyglibcat/020103toxemia/02010301.html
Try telling that to the parents of a boy who was ordered by the American judicial system to undergo conventional chemotherapy-treatment for his cancer, rather than opt for a more successful alternative route; even though the odds of surviving longer than 5 years after chemo' are approx' 3% at best.
I do understand your stance/viewpoint, which is best described as the current medical paradigm of treating disease, and accepted by most as they are an "authority", but one day you may educate yourself to know better than this (as I did, and thousands upon thousands of others already have) and realize the folly of this position.
