I am currently working on a video of zapping worms in a water based environment using the MY. The worms seem unaffected until the zapper switches to s specific frequency, upon which they react almost immediately, within a few seconds, and most are dead by the time it changes to the next frequency. In other modes, that do not have a frequency that they are affected by they survive for a couple of hours.
That's good news. I hope that you will do these kinds of experiments and have the same results with parasitic worms which are commonly found in humans.
