Have to say, I'm a great believer in orthodox science, and take on board all the points explained here about the physics etc of electricity and magnetic fields. I do feel a bit silly, and I admit it. But I still have these reactions. Maybe they're psychological (or 'neurotic' as one poster suggested) I'm quite reassured by the lack of risk explained here, so thank you. Will try to drag myself into the 21st Century and accept modern installations and development, but still have illogical reservations!
