There's a big "controversy" in my home town about flouride in drinking water. One of the pro-flouride dentist wrote a big article as the definative view of science and medicine in the local paper... stating how flouride is soooooo good for you. Anyway he stated "flouride has been used for over 50 years in our water supply without any effects on the population".
After reading it I went downtown and noticed half the population walking around like zombies......... hummm, no effect on the population.
There is a new movie coming out "Flouride Zombies of the Southwest", don't miss it, its being filmed here.
