Magnet implants in finger
People have been implanting magnets into their ring fingers, to get a kind of sixth sense. I’ve had something like this thanks to my steel engagement ring–I can tell where the security magnets are in shops, etc. I was thinking of making a magnet ring, problem might be keeping it clean and unspiky, considering all the metal filings that would leap up and stick to it? Might work as an emergency compass, though.
