Bob Wehadababyitsabo writes: The Wall Street Journal Health Blog writes about a fascinating medical case involving a jogger, his iPod, and a thunderstorm. "[...] witnesses said the poor guy was thrown eight feet by the electrical discharge. Both his eardrums were ruptured, and his jaw was broken. The first letter [to the New England Journal of Medicine], by doctors who treated the man at the hospital, argued that 'the combination of sweat and metal earphones directed the current to, and through, the patient's head.'" However, a letter in NEJM's Thursday issue disputes the original findings, instead suggesting the iPod earbuds served as a lighting rod, directing electricity away from the patients ears and head and toward his torso. The verdict from the second letter? "A final note on jogging in thunderstorms: much of the very interesting debate that has followed the publication of this case report would perhaps be unnecessary if common sense were as ubiquitous as the iPod."
