Just look at all the people driving whilst using a cell phone. Whilst driving to and from my client in Florida, I saw several cars being driven by idiots, like this one on the right.

Do Cellphones Cause Brain Cancer? Was a recent article in the New York Times.
Now there are all sorts of articles claiming all sorts of virtually unprovable effects. I know of physical effects that my colleagues felt and exhibited in my lab. But that was at a much much higher level of power. Now some other organizations are arguing for a complete disregard of the WHO report. Far too many have a vested interest in this for a realistic finding.

Still I do feel by the evidence witnessed by me, that the cell phone inside a vehicle is a dangerous distraction to the driver. Maybe the R.F. is interfering with brain function.
