I actually saw this documentary... I always wonder about the weird things, like how are they going to handle the job world, and applying for college. What if they want different majors? Can one get a credit card, and the other not be held liable for the debt? The coolest thing from the documentary is that each girl has independent control of one arm, yet they perform tasks and motions seamlessly without discussing it. They have the hand/eye coordination and dexterity that everyone does, but essentially their brains don't communicate with eachother.
