The individuals who claim that they are sensitive to mobile mast emmissions seem to display, should their claims be true, a remarkable ability to biologically filter EM fields depending on their intended use, completely ignoring the TV, radio, and other bits of the spectrum which swamp our atmosphere whilst being affected negatively only by EM waves intended for mobile phones.
Another somewhat surprising aspect of this effect is that it only appears to happen in the UK. Perhaps these types of people can also filter out archaic 2.5g tech, and thus are not affected in the United States, where nary a word about masts is spoken?
As far as a solution to this paranoia goes, my only suggestion is this: tell these Luddites that the masts are being cranked up by 30% every day until they keel over from the self-inflicted placebo effect, and then the rest of us can live in peace.
