Forget brain radiation
Yikes! Three possibilities come to mind.
(1) The phone itself makes you more likely to get hit. (But what cellphone today has a significant enough amount of metal on it?)
(2) Lightning bolts can follow the invisible paths of cellular radio signals right to the handset. That’d make a great urban legend.
(3) Standing under this tree using a cellphone makes you more likely to get hit. But then why this tree? (There were other signs around following no discernible pattern.)
Seems to me that it must have something to do with the phone being on, otherwise why note anything?
This reminded a colleague of mine of a story of a woman in a park in London killed when lightning struck her bra underwire. Only one way to prevent that, I think. Be safe, ladies.
