Consider the following scenario: A burning building, relatively structurally sound, is engulfed in flames, with 4 small children trapped inside. There are two people who must decide how to respond to the situation: Granny -- an 80-year-old misanthropic, pyrophobic, luddite, who saw her mother burn to death in a fire when she was younger. She's in relatively good health, although she uses a cane. She has a cell phone for emergencies, but she hates it. Clark Kent -- a 30 year, world-renowned firefighter who is on his way back from the latest firefighting championships. He has all his gear with him but, like Wolverine in the X-men, has loads of superpowers, so he rarely needs it.
