How does a child or maybe an adult get sick because of Wi-Fi signals? That's very, very odd.

Answer 1

Odd? I don't think so. We get all sorts of weird questions here, the only explanation that I can see is that brains have been radiated with WiFi for an extended time.

Answer 2

Answer 3

Odd is that this article appeared in my paper today as I was reading your question.
