As, aging, your body's components began to wear out, or flatly fail, science provided durable, reasonably priced, guaranteed replacements. Although no longer possessing flesh, bone, and blood, you feel that you do---that is the remarkable, and comforting, stability provided by this technology. As the world's politics continued to deteriorate, an ancient---but completely functional---cobalt bomb was found by disappointed excevators. Instead of display as an educational relic from the distant past, it became the flagship of an arsenal; and was, in a sudden fit of temper, detonated (your grandchildren's grandchildren's grandchildren having left no words of wisdom or warning for their grandchildren's grandchildren). Propped up against a rock, unable to move now due to absence of both replacements and repairers, your body degrades---by fractions, of which you are painfully (oh, that unexpected, unforeseen pain) aware. The last of the guaranteed improvements---the multi-layered, multi-dimensional chip that contains your mind---was said to have a half life expectancy of centuries. Around you, the decomposed debris of what were once living and breathing human beings---the numerous family of descendents of which you were the established, though virtually ignored, patriarch---continues to change nto unrecognizable patters, textures, and colors. The various changes of solar, stellar, and lunar movement have been reduced to two---light gray or dark gray---the diurnal and nocturnal tints of the radiocative cloud that now ensheathes the wreckage---the mass graveyard and junkyward---that was once the thriving and vivacious earth.
