lightning warning to ipod users:conducts the electricity

                           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 travelled through his music player's wires.
                                                             Lightning strikes can occur even when a storm is many kilometres away, so lightning safety experts have been pushing the slogan 'When thunder roars, go indoors'. Packaging for iPods and some other music players do include warnings against using them in the rain. 
right, right, right!!!

Electronic devices do not attract lightning the way a tall tree or a lightning rod does. According to Dr Mary Ann Cooper of the American College of Emergency Physicians and an ER doctor at University of Illinois Medical Centre at Chicago, once lightning contacts the metal,the metal conducts the electricity. When lightning jumps from a nearby object to a person, it often flashes over the skin. But metal in electronic devices - or metal jewellery or coins in pocket - can cause contact burns and exacerbate the damage.


Facts
-The average number of lightning strikes worldwide per day is 8.6 million. 
-Count the number of seconds between the time you see the lightning flash and hear the rumble of the thunder. Divide by 5. The figure gives you the distance in miles of the lightning from you.
-The average lightning flash would light a 100 watt light bulb for 3 months.
