I still wanna know the story 5,000,000 years into the future

If you go back and look at some episodes, but Jack actually says- he rattles on a bunch of lines on how he has been killed and one of it he says "I've never put my head on a railroad track". Right away I thought, all of a sudden, that's how it happens. Jack just experiments one day. He gets up and his body just goes but his head is just there. I'll probably be 95 by the time they film that episode so i'll really look like the face of boe.
