If I didn't think you were crazy enough to hunt me down, I would provide my credentials-- I assure you, I AM a doctor. Have been for 14 years. I am also a tenured faculty member at a major medical school.
Maybe the bath-houses YOU hang out in have rampant contamination by drug-resistant strains of staph, but I can also assure you that billions of people on this planet have had burns and other "openings" in the skin without dangerous infections.
I must acknowledge that I do not know for a fact that the infected DRG cells were killed. But I DO know for a fact that I have had no epidermal outbreaks and that none of my sexual partners has reported infection (and most of them have remained close friends for over four years).
I am not trying to fool anyone. I am just trying to share my experience and the hypothesis that led me to try it. If I wasn't busy trying to cure multiple sclerosis, I'd get a(nother) grant to study this strategy in the lab.
You are now free to go back to filling the web orders for your "Zapper" or herbal tea or whatever it is you're hawking.
