Some of the questions and comments here are really stupid. I saw the latest documentary also. To the moron who commented about the school lunches: the twins have SEPARATE stomachs. The show clearly told this. They have one food tray because of their physical form.
To the imbecile who asked about committing a crime. How could one commit a crime while the other is asleep, if -- in order to walk, BOTH twins have to be awake? They each control one leg. If one was asleep, the other would have only one leg with which to drag half a body of dead (asleep) weight.
Jeez, some people with one head have HALF a brain.
