This video considers how the strong electromagnetic fields that are present in the proximity of highly conductive silver and gold may impact on the human brain and facilitate mind control and social engineering.

I was wrong about Tin being highly conductive. I wish a metallurgist or electrical engineer would give some input here.

The name of the metals are on the left and the conductivity level on the right...
