I did not realize that this device has been around for 10 years so that such a longitudinal study could be completed.
Sample size? Citation to this study??
(P.S. I type this as my cell phone is sitting on my seat tucked slightly below my nuts...good thing I already have two kids already!)
Hmmm, doesn't it use radio waves? I don't think those can give you cancer. I haven't heard any reports of people working at radio stations getting cancer, and those huge antennae give out way more powerful waves than this.
