It is important to know where he was and what he was doing. Was he stuck in the sewer with Bane for 6 months? When they showed him setting the bomb, he didn't appear to be in rough shape at all, even though he had been watched over by LOS members for that entire time. You would think he would have gone crazy by that point.
