Wow, jusy wow.. What this study proves is that the world is still untouched by the poison we all have to endure. Civilisation has become toxic in many forms and overpopulated. Too many beliefs. Too much hate. Too much darkness. These people are lucky to be where they are. Many won't see it that way -- I do. Let them stay how they are. It is refreshing to know about these people. It will be sad to find out ithey have fallen to our way of thinking. Do not ever let "outsiders" in. KEEP US OUT!
