| the video "Professional Perspectives: Fluoride in Tap Water" @ 1:45, says 8 oz of water has quarter mg of floride, and people swallow that amount should contact poison control centre. When i was in HK, i drank more than 2 litres of water a day, i should have gone to the emergency many times... and most of the people in water floridation countries should be poisoned. |
