If anything went into the water, I think iodine is better than flouride or chlorine. Saw a picture of a canal or something in China where they had a man with some kind of tub or something positioned over the water so he could slowly drop iodine into the water. It might make people smarter though and we can't have that! It's probably not a good idea to use the water supply to medicate people. Something about the ethics of it.
I remember this company from seeing its name on money in Central America more than 40 years ago. They also printed US money before the federal government did. Relevant, interesting or both?
