Tony, you have to ask yourself why Humble would make such a statement after the time he has spent promoting MMS in video's, books, and his web sites
It doesn't compute for me, and the fact that so many others have made video's, including doctors about MMS's efficacy surely trumps the verbal exchange between you and your friend. At least for me.
That's what it's all about though, making up your own mind based on the information available.
