Until such time as duplications of individual nervous systems can be grown in tissue cultures (at this point no one knows "whose" consciousness they would have), our special identities will always be subject to being hit by a truck or dying in a plane crash. A sudden virus or heart seizure, even in the body's youth, may carry us off. Statistically, looking ahead thousands of years, the chances are that every human and even inanimate form will be broken sooner or later. But the distress felt by men and women today does not arise from the fear of such hazards. Rather, it comes from the certainty of aging and physical degeneration leading to death. It is the fear of losing our powers and being left alone, or in the hands of indifferent nurses, and knowing that the moment must come when we will not see the people we love any more, and everything will go black.
