Magnetic Braclets
I have worn a magnet that you place in your pockets or in your bra (if you wear one) for years. I wasn't really able to see the difference but was told it was doing me good.
Yesterday I bought a magnetic bracelet and I can really tell that this one is doing me good. It is keeping me a little warmer for one thing. I am always cold and even now I am sitting here tying with my little Linus blanket wrapped around my legs, but I am much warmer than I am normally.
