that's in fact, what we learned, the worst time to be doing that, and here's why. your phone is not always giving off the same amount of radiation. if you have a poor signal, if you're having a hard time hearing the person, in fact your phone is trying to compensate for that. your phone is trying to give you a better signal, and in the process of doing that it is e t emitting even perhaps more radiation. this is a constant process. it's constantly communicating with cell towers. further away from a cell tower, the sort of remote region that you're in, it could actually be exceeding those fcc limits as far as radiation goes, trying to give you a better signal. >> and you've always used a wired earpiece when talking on the phone. is that radiation-free? >> well, you know, it's interesting. it's not radiation-free. and again, this has been a learning experience i think for a lot of people. but even the wired earpiece, which i carry, as you know, everywhere, it does have some, for example, wiring that may transmit some radiation up to the ear as well. so it's greatly reduced versus a cell phone, certainly much
