By Tuesday at dawn, Dr. Haynes estimated the core body temperatures of the Indy’s boys were probably hovering right around 92 degrees. Later, after the shark attack, as the sun rose and baked them, their temperatures began to rise a degree or two, perhaps as many as five. In essence, the boys had fallen into a pattern of abrupt energy drain and renewal. But increasingly, they were building a deficit that eventually even the heat of day wouldn’t be able to erase. With their body temperatures dipping low, the boys were wobbling off into the land of fatal judgment.
