You hear about this phenomena from the majority of people who find themselves close to death. That begs the chicken/egg analysis: do they "see" their life pass before their eyes because that's what they expect to see. . . or is it a real phenomena that occurs as a result of loss of oxygen to the brain?Or, could it be the brain "downloading" or backing-up its data, to be restored at a later time, or on a newer machine?Maybe that download of material is proof of another life to be lived? All of that experience, reduced to data, would be necessary in our "next" life, if we are to believe that its important to learn from our mistakes.
