There is an architect here in Baltimore who advertises that he can relieve your immune system by grounding electrical currents and minimizing exposures. This architect has training in the German science of "Bau-biologie", building biology.
He says that restless sleep, inflammation and high blood pressure can result from incorrect wiring. I know what he's talking about! Whenever I come home from camping, I feel like the electrical current is sizzling through my skin. I supposed this might be part of "sick building syndrome".
