Alright. thank your for the clarification. I was under the impresion that muscles only needed electricity to move, but I'm not sure why I thought this. After muscles are composed of cells just like any other tissue so they need oxygen in order to carry out their metabolic processes. Well back to the drawing board. What about a parasite or virus that caused evelvated levels of testosterome, an exellarated metabolism, dialated pupils (sensitivity to light) raised aggression, resistance to pain, and a lack of higher mental computation. Plausible?
