dr mercola's newsletter on led lights is fascinating, suggesting they have effect on aging/mitocodria (read energy)
a comment on same newsletter, suggests I don't have to worry about getting led tv, that it's frequencies that make the difference. he said we are like robots that run on frequencies...............? wish I knew more about this! anybody? I do know we (synapses?) run on .07 volts and I just bet it figures in pd.
