Subject: Re: high-voltage lines
A TV programme I watched a year or so ago did an interesting scientific
experiment re waves
from radio masts.
They put volunteers in a house in the middle of nowhere and asked them
to record their
symptoms each day.
They found far more symptoms reported when the volunteers could see the
radio mast set up
in the courtyard and were told that it was functioning than when they
were told it was
switched off.
There was no relationship at all between when the radio mast was
ACTUALLY switched on
or off (the researchers lied!)
(They'd actually done a proper literature search too - or properly
reported one that had been
done - it was a v unusual programme in that it was evidence-based! It
also included
interviews with people who were convinced their health was affected by
local masts but they
were not at all convincing).
