Because of some news:
Israeli intelligence was reportedly able to track down the location of Iranian General Mohammed Ali Allah Dadi, who was killed in a strike attributed to Israel last week in Syria, via his cellphone, Lebanon's The Daily Star quoted Lebanese newspaper Al Joumhouria as saying on Sunday.Now, you may laugh at me, but I'm real sensitive to the problem of safety where all these new-fangled electronic gizmos are concerned.
I have perused the FDA site re this issue. While there is a mention of possible damage: "Two areas of the body, the eyes and the testes, are particularly vulnerable...", somehow it didn't match the picture of catastrophic failure of all the organs in the body. Like it happened to the general in question and his entourage.
So my advice to you all: switch off your cellphones when going out. Remember - it is just humans that write the software that guides these damn drones and launch these damn missiles, and you never know. FDA should add this to their site too.
It is your health, after all.
