Health experts have recently put out a warning telling people not to use their iPods, cell phones, or other electrical equipment while outside in a thunderstorm. This seems like a redundant warning, since you aren't supposed to be out in a thunderstorm anyway.

The warning comes after a man, who was jogging in a thunderstorm while listening to his iPod, suffered severe injuries after a tree near him was hit by lightening. The electrical equipment, in combination with the sweat on his face and head, conducted the current through his skull, breaking his jaw and shattering both of his eardrums.

So if you get caught out in a storm, take a moment to turn off and put your personal devices away, and then get thyself to some shelter. In case you need a refresher course, here are the rules of thunderstorm safety.
