I don't carry a cell phone either. I don't care about biophysical effects as much as I do other side effects of carrying a phone, such as that they track my location for creepy stalkers. I think they also at least sample audio, and would video but I cover the camera lenses. Cost me a couple hours walking today when my truck broke down, but that's probably good for me anyway.
Thanks!
I'm on the exact same page. A lot of people just can't give up the convenience. Thanks again for your comment.
