A keychain you carry in your pocket is somehow supposed to discharge your static charge? I'm sorry, but electricity does not work like that. Unless the keychain has a ground wire of course, but the things image search showed me are just as effective as touching coins in your pocket.
I was thinking one of those sci-fi medical bays that rebuilds healthy bodies on a molecular level. Would like some of my amputated body parts back in addition to a cure to my ailments, thank you very much.
