“One who voluntarily deprives oneself of food may live twice as long as one who is forced to be without food. Similarly, you can choose to go without water for several days, but if you are deprived of it, you die more quickly. The older men survived because they had resaons to live - a garden to finish, a wife to see to, and grandchildren to help raise - whereas the younger men had less encouraging them to return (from battle). Strong wills become more crucial than strong bodies. It was this principle that inspired the establishment of Outward Bound. Yet, more than two millennia earlier, Alexander led his troops out of the desert with this same principle.”
