Here's a question for scientists only.
It has been demonstrated that metal amlagam dental fillings generate electrical potentials with magnitudes of up to 350 millivolts. See:
Does anyone think that the fact that the static electrical charges generated by some articles of clothing may be measured in many thousands of volts somehow proves that the electrical potentials generated by amalgam dental fillings are not able to dissipate electrical energy through the nerves in people's heads?
And, if so, how does it?
