Jim Humble's position apparently changes depending on who he is talking to and what position might benefit him at the time. According to my friend, who is the Director of the International Wellness Directory (aka the Minnesota Wellness Directory), who has never once told me an untruth, Jim Humble told him over the phone that MMS itself did not kill pathogens. That leaves only oxidation as far as I can see, and, like chemotherapy drugs and radiation, it is NOT selective.
