Theres also the heavy metals and other toxins that are stored in our cells too though isn't there?
One thing that strikes me is what if these metal and toxins are holding energy by way of a charge once the cell has died? Wouldn't this keep the cell alive even though it was dead and allow it to mutate. Seems a plausible explanation given the facts that pollution and cancer levels seem to have grown together and antioxidants are the best preventative methods offered?
