Shaken, but not quite 23 July 2005

After a series of bomb blasts in an Egyptian resort (almost 100 killed and many injured) a BBC World presenter was talking to a British policeman on vacation there. He had earlier taken part in the police operation in London after the suicide attacks there; he had been only 50 meters from one or two of the Egyptian blasts, and had seen all the carnage and mayhem they had caused. With all this in mind, the BBC presenter said something like: “You are obviously quite shaken…” The policeman confirmed, but he sounded totally in control and relaxed. What kind of brain can possibly generate such utter composure (other than the Sitting Bull’s)?
