Copper, titanium and other metal bracelets have long been promoted for arthritis relief, but now the idea has been taken a step further, with baubles designed to relieve stress and even help you play better. Callaway Golf has gotten into the act with a bracelet line called IONETIX, which includes a stainless steel version embedded with magnets. The product is designed to create "an overall feeling of well-being." The theory is that modern life, with all its electrical gadgets, loads our bodies with an excess of positive ions, which are balanced by the negative ions emitted by the jewelry. Some scientists have suggested that the bracelets offer little more than a placebo effect, but hey, your mind screws up enough of your roundsmaybe it's time it chipped in something useful.
