The research is conflicting. The test will soon be available in the real
world. If mobile phones are such a threat then given their extensive use we
should start seeing early onset senility occurring in droves quite soon. I
think that with the old analogue phones, which requires circa x10
transmission power, there was a potential problem but the digitals appear
safer. Whatever, I hate the bloody things, have never owned one, and failed
to see why most people are so bloody anxious to be kept in touch with the
human race. Thus sayeth the hermit ... . You may recall that initially the
worry was cancers. Well that bugbear has fallen by the wayside, now there's
a panic about the blood brain barrier. Whatever, the research must be done,
in the interim my general take is that anyone who uses a mobile phone that
much to induce any possible damage deserves what they get.
