Okay, I will add my thoughts....E
Because of my major...I have been able to talk to Electronic Engineers. This topic brought me to ask a contact of mine who is a professor in Environment studies....
One engineer told me when I asked him told me that no studies have shown that WiFi can cause health issues in particular. He said that some symptoms that people have experienced (headaches, and dizziness) are psychosomatic.
This is the side of an Electronic Engineer though.
