Oxidizers added to gasoline, THE SOURCE OF ROAD RAGE, demand that everybody take a good antioxidant supplement. Further, this gas additive has been aggressively leaking into groundwater from aged tanks. This demands a carbon filtered water system, which can consist of a $30 tank and carbon cartridge emplaced on drinking water, either in the bathroom or kitchen. Drop a fine silver wire in the bottom of the tank to kill all tank slime and bacteria in the filter medium. 14 gauge FINE, NOT STERLING SILVER wire can be obtained at: C.C. Silver & Gold in Phoenix, Arizona. Shalom!
