You are not a doctor, and you have ZERO qualifications, to parley this nonsense as real knowledge of parasites; lying that Zappers kills "parasitic organisms"; you have no medical knowledge of parasites to begin with, what kind of specific parasite one has. How you dare make these false claims here, trying to dupe folks! What you are doing is immoral and unethical. Have some shame! Take zappers elsewhere, I suggest some street corner!
