Fluoride

Just reading stuff lately on how bad fluoride is. I was always kind of anti- water filtering, but there seems to be alot going on with fluoride. Most of Europe quit doing it. Fluoride calcifies the pineal gland, which is involved with wakefulness, which is something I'm concerned with. Not sure what to do about it. I know fluoride is poisonous for cats, but we give them fluoridated water! Perhaps buy bottled water? Or a reverse osmosis filter?
