Have your kids do this:
Take a slice of bacon, put it in your microwave oven, turn it on for one minute.
Then tell them, "If this microwave leaked as much energy as your cellphones and iPads put out, it would fail the safety test at the factory and never be sold."................
So if a guy carries a phone in his pocket is he going to get cancer in his gonads or prostate? Earphones causing brain cancer or just a lower IQ?
