metric system is a Commie plot just like fluoride in water.
In 1861 Commie Agents armed with #1, The Metric System and #2 about 2,000 tons of CaF2 infiltrated the US. Traveling first to Colorado Springs where they located the towns aquifer. Digging down several hundred feet they buried about 500 tons of the CaF2 into the aquifer. Next they traveled to Oakley, Idaho locating a warm spring about 5 miles from the town the once again contaminated the spring with CaF2. Lastly and most insidious they traveled to Bauxite, Arkansas where ALCOA was building a company town to mine and process bauxite to produce Aluminium metal. Once again the heinous Communists contaminated the nearby aquifer with CaF2. Unfortunately for the Commie Plotters the Civil war was ending and they could no longer do their dastardly deeds unnoticed.
The CaF2 slowly dissolved in the aquifer entering the towns water supply. Soon children began to me born with discolored brown teeth. No self-respecting White-tooth wanted anything to do with the brown-tooths so inbreeding began. The brown teeth proved almost immune to tooth decay and so the brown toothers ate better and lived longer. In Bauxite Arkansas rumors were spread that it was Aluminium causing the brown teeth...Aluminium must be poisonous and more and more people began to reject anything made of the new metal.
1901 Frederick McKay a young dentist moved to Colorado Springs and was appalled at the number of chocolate brown toothed people and children in the town AND the fact that these brown teeth did not decay. He began to searcher the condition which he named Colorado Brown Stain.
In 1909 a world renown dental researcher G V Black arrived to assist with the research. McKay began to suspect something in the town water was to blame.
In 1923 McKay heard of the brown-toothed residents of Oakley, Idaho and was able to convince the town leaders to give up the sprig that they were using for the town's water and move to another spring. Within a few years newly born children had normal white teeth. McKay now knew that it was something in the water but could find nothing. Then the Brown-toothed residents of Bauxite, Arkansas drew McKay's attention. McKay called in Dr, Grover Kempf of the USPHS to assist but neither was able to find the problem. The reports produced by McKay and Kempf caught the attention of ALCOA's Chief Chemist H V Churchill who had been fighting claims that Aluminium was poisonous for years. Churchill decided to do a much more through testing of Bauxite's water supply using a Photospectrographic analysis. At last success and Churchill reported to McKay that the towns water contained high levels of FLUORIDE. Water samples from Colorado Springs and Oakley showed the same high levels of Fluoride.
In 1931 Dr. H. Trendley Dean, head of the Dental Hygiene Unit at the National Institute of Health began investigating the epidemiology of fluorosis and its effects on tooth enamel. Dr. Elias Elvove, a senior chemist at the NIH had developed a test for Fluoride in water accurate to 0.1 ppm. Through these studies it was determine that Fluoride levels of 1.0 ppm did not cause the brown-stains and still maintained the decay resistant teeth.
In 1944 Dean, the US Surgeon General, and the Michigan Dept. of Health convinced the City of Grand Rapids to add Fluoride to the cities drinking water. In a 15-year study 30,000 children born after the addition of fluoride were monitored for tooth decay. Tooth decay in Grand Rapids had dropped by over 60%.
Dean had not only foiled the Communist plot but it had yielded an unexpected added boon.
