Grubby: Not everyone rolls their eyes to the ceiling but certain people do. There was some research a number of years back about detecting deception (lies) and one of the indicators had to do with which direction people rolled their eyes up - diagonally to the left or to the right when answering a question. It had to do with the right brain / left brain phenomena that was so popular. Unfortunately I can't remember which direction susposedly indicated truth and which indicated deceipt.
