I've met at least two people in my lifetime who had 2 or 3 language processors in their brain. They could type unrelated sentences while listening/speaking in a different conversation. That's not me, though - I can't even finish typing a word I've thought of if I'm trying to listen to someone talk or say something to them at the same time. I have 1 language processor at the best of times.
