HERE IS A LINK TO LIFE SENTENCE. Editor Paul Levitz had changed the original ending to this story. The original version turned on the notion that cloning would result in advanced aging because age occurs on a cellular level, and the resulting clones would be biologically as old as the cells from which they were grown. This was theoretical at the time the story was published, but since has been suggested by actual experience with clones.
