Okay, virtually. Apparently magnets will last forever, unless heated over 250 ?F. Thanks a lot, heat! Now onto the fun stuff! The Magnalinx Magnet Bracelet doesn't just resemble a cool old timey bandolier belt, it's apparently doing something...to you! Some people say that experiencing the magnetostatic fields produced by the bracelet can cause beneficial health effects. Now I'm not a doctor, a member of the FDA, or a scientist (unless loving cats is a science), but I do think these look rather groovy and would definitely benefit from some stress relief! Hey, some cats are jerks!
