You ever been to a shop that sells TV's. when you stand next to the wall of TVs i can just feel too much electricity. even with eyes closes you can feel too much electrical in the air. Wifi probably does the same thing, it is a health issue. it like can you taste all the applied pesticides on your food? no. but they are Still There!!!
I can't say I've ever noticed myself but I'm sure we all have different levels of sensitivity. Our bodies are flowing with our own electricity so it stands to reason that external factors could affect us.
Though I'm not convinced about these people who have to move to that area administered by NASA that has no waves at all to escape their horror, I do think it's within the realms of possibility.
