Don’t use a mobile phone in a storm?

I’ve seen this reported in several places, MSNBC [], Slashdot [], The Guardian [], and others:

in a letter to the British Medical Journal that usually when someone is struck by lightning, the high resistance of the skin conducts the flash over the body in what is known as a flashover. But if a metal object, such as a phone, is in contact with the skin it disrupts the flashover and increases the odds of internal injuries and death.

So my questions is what about other metal objects that I have one and are in contact with my skin all the time? What about my glasses? What about my earrings –surgical steel? What about the copper rivets and button or zipper? Am I going to be lit up like a Christmas tree the next time I take a walk in the rain?
