I use to tell my grand kids that all the time, they'd be sitting on the couch with their cell phones sitting on their Johnson, which is what we call it now after I ran across this video one day, which really helped my pleading calls...
I also tell them to think of it as a cut up peanut, because they try convince you it's such a low dose it doesn't cause harm, but if you took those small cut up pieces of peanuts and putting it back together, eventually it's a whole peanut again, if you throw it in a jar, cut up another peanut and did the same, eventually, over a long period of time, the jar will be full.
That women you were talking about, wonder if it was the same one on Dr Oz show years ago. If so I didn't know she had died but back then she was still alive talking about how she put her cell phone in her bra and got cancer in the exact spot she put her phone in her bra. That story I've told several times to women who I knew did that and it convinced them to stop doing it.
One other really alarming thing is people sitting with infants on their laps while being on their cell phones, I tell them baby's skulls are fully developed yet and they can absorb greater amounts of those so called low doses of radiation.
