In this past year's Olympic games we were reminded of the extraordinary endurance of certain athletes like the marathon runners and decathletes. These events are always among the most popular in any Olympic competition. There is a special fascination with people who seem capable of endurance beyond any reasonable limits, whether those are the limits of athletic competition, like a footrace of over 26 miles, or persevering in the face of lengthy illness or adversity. We know eventually those limits will be reached and the efforts of the competitor must cease as all resource is depleted.
