I've seen solid copper braclets. I've seen chain copper bracelets. I've seen magnetic braclets. All of them claim to do one thing or another, but is any of it true? It sounds a lot like BS but then again, humans do have strange fields around them. When I'm near a radio, I cause lots of interference. My best friend's mom sets off theft detectors whenever she walks through them (even when she's not stealing things ). Do any of these bracelets do anything?
