how about the cruise character finds the following document on the DiNiro character:
and he wonders why the hell he's still 50 years old after all this time? It could be some sort of experiment he was working on . . . like some performance enhancer that made him age slower? Kinda like an X-File within the story . . . some sort of age-defying concoction that the NWO was working on so the powers that be could remain in power longer, only the Dinero character (or rather sheridan) didn't know what it was. He could have watched his family grow old and die while he is still young . . . and the NWO doesn't want the public to find out. There could be an existing hit on him, only the operation to kill him was hush-hush?
