It is exasperating how little we know and just as frustrating how much we assume. The electrical potential of the cells in the human body function in a very narrow range, that much we do know. It doesn't take much to effect that narrow band. Our bodies are paramagnetic. Wave potentials increase when exposed to magnetic fields. The Ti book releases those fields, albeit at low levels. However, even low levels can be amplified through environmental exposure. As Paul eluded, living is risky. When it comes to our bodies we have to be the resident experts. ...Or at least die trying. :-) MBurke
