Thanks for the input, David. I think the immune system plays a part, so that may be the best we have right now to strengthen that. I guess time will tell. I was asking myself the questions, and realized I could not answer fully to some extent, and certain scenarios are possible, everything is, but not likely, as Brian Hill explained, and dare not to try to explain his input. Maybe after reading it 10x lol. I hope the study comes out, fairly quick, but probably takes time.
