Some people believe that the human tongue cannot be tamed (because the bible says so?). Ha, then you do not know the truth at all. Not all the people you see walking around are human beings to say. Some are from the other side, some from the underworld, and some a possession of demonic spirits.
So, inasmuch as humans cannot be tamed but animals tamable, it means that humans who behave like animals or demons can be tamed scientifically.
