From the Boston Globe:
Listen to an iPod during a storm and you may get more than electrifying tunes.
A Canadian jogger suffered wishbone-shaped chest and neck burns, ruptured eardrums, and a broken jaw when lightning traveled through his music player’s wires. Last summer, a Colorado teen was hurt when lightning struck nearby as he was listening to his iPod while mowing the lawn.
Emergency physicians report treating other patients with burns from freak accidents while using personal electronic devices such as beepers, Walkman players, and laptop computers outdoors during storms.
