———. 1962. “Cardiovascular Studies in the Samburu Tribe of Northern Kenya.”American Heart Journal. April; 63(4):437–42. Why had the city flooded? A bad storm. The loss of a wetlands buffer. Most of all, around New Orleans, the levee and flood control system—increasingly federalized after the 1927 Mississippi River floods and managed by the US Army Corps of Engineers—was grievously and predictably faulty. The failure to address its known weaknesses had saved money in the short term and now appeared outrageous. Piaget, Jean, ref 1 Our propensity to alter our behavior in response to physiological needs is what the Johns Hopkins physiologist Curt Richter called, in a heralded 1942 lecture,“total self-regulatory functions.” Behavioral adaptation is one of the fundamental mechanisms by which animals and humans maintain homeostasis. Our responses to hunger and thirst are manifestations of this, replenishing calories or essential nutrients or fluids. Physical activity, as Richter suggested, is another example of this behavioral regulation, in response to an excess or dearth of calories. “We may regard the great physical activity of many normal individuals, the play activity of children, and perhaps even the excessive activity of many manic patients, as efforts to maintain a constant internal balance by expending excessive amounts of energy,” he explained. “On the other hand, the low level of activity seen in some apparently normal people, the almost total inactivity seen in depressed patients, again may be regarded as an effort to conserve enough energy to maintaina constant internal balance.”
