I got involved in a discussion years back in which some completely cüntwitted prick from the UK was banging on about the damage that fluoridation was doing to the bodies and minds of the people in the city where he lived . Something made me check the fluoridation status of various areas in the UK and I discovered that the area he was talking about had quite adequate levels of natural fluoride in their water supplies so they were never subject to articifical fluoridation!
In fact very few areas of the UK ever added fluoride to their drinking water as it is rarely necessary.
