Cancer woo woo
My ex and my mum both believe in this wireless makes you ill moonshine, but it's something they won't shake, it's the judgement of huge numbers of people who won't be disabused of it. I feel for them. Some very bright people are like this. I won't hear it said they're stupid. So they don't reason like you or I, but you and I have a certain conception of risk and trust and so forth too, that's not all pure reasoning. The whole Better Call Saul subplot about Chuck McGill is a painful illustration of such tormenting and incorrect beliefs that are in practice unshakeable.
