I don't know. I did do a little research on fluoridated water, I found that some who were a part of that decision fell away from it, they decided that it wasn't doing anyone any good.
Recently I found out that Fluoridated water could cause arteriosclerosis. Arteriosclerosis is what Stalin suffered from, I don't know how he got the condition. But apparently late term arteriosclerosis caused Stalin to fail at distinguishing a good act from a bad act. Maybe that's why we have so many Democrats turning left, and our US government with so many corrupt people in it. I might be wrong about why that is, but I'm only speculating.
