Ten years after the movie they have gone and done it. We now know how the genetic make-up of human beings. Some Job descriptions even say without consideration of age, race, religion or genetics. We also have electric cars and wrist radios. This is no longer sci-fi; it is speculative fiction. Or at least it is speculative. Anyway I have a friend that had a back problem in his youth. They left some dye in him and it was spotted during a job interview physical for a desk job; you guessed it.
