  • "All night long as they lay in the snow, their bodies had fought to keep warm by drawing the blood away from their skin and exposed extremities and pushing it deep into the core. In the morning, when the boys stood up and began to walk for the first time in hours, the sudden change of position and unaccustomed motion triggered a massive fall in blood pressure. Blood from the cores of their bodies cooled as it moved into the cold extremities. Their pumping hearts forced this chilled blood to circulate. When it reached their hearts, the boys instantly went into ventricular fibrillation. Instead of contracting and releasing in steady rhythmic beats, the lower chambers of their hearts began to quiver without coordination or effect. Pumping quit; blood stopped circulating... Jesse and Omar blacked out. Ten or fifteen minutes later, their fibrillating hearts ceased to beat altogether and the boys died."

    —David Laskin, The Children's Blizzard (New York: HarperCollins, 2004), 207–208

    I wish the guy had explained what the boys should or could have done, rather than getting up quickly. Could they change positions slowly? What should they have done to warm up more slowly, if they were still out in the cold and getting up to go for help?
