>- Many of them have probably no idea of what kinds of organisms they were infected
That is just another of your excuses.
>- The only way to know if a specific frequency is effective to kill a specific organism would be to do an experiment with contaminated water/blood and analyze this water/blood with a microscope...
Yes, there are videos on youtube.
>- With all the money that you have earned by selling zappers
You really do not get it. If I was making the kind of money that you imply, I would be able to make car payments instead of driving a 16 year old heap.
>- you could do some experiments with contaminated water/blood,
I have done some of these too and reported what I have seen but all you do is defame. It is obvious that your objective here is not to find information but to suppress and discredit it.
