On reference I also seen this program, the Castle was situated in
Edinburgh. But we must realise the amount of EMF needed to produce
these effects are quite large and are normally produced by man made
equipment and not found in nature unless you are around a siesmic
event.
EMF pulses are not produced by nature and the amounts of EMF which
are produced normally may come from pesso effects as the weight of a
building crushes small crystals in the rock used in a buildings
construction.
These effects do not effect us in the way which we where lead to
believe, if that was the case we would assume we always have the
sense of being in a crowd of people as we have TV's, VCR, washing
machines in our home which produced more EMF than nature.
