Abstract

Our society has evolved in a remarkable way. When humans first appeared, they were essentially hunters. Survival could be assured only by hunting and not being hunted themselves. Although humans were at a physical disadvantage compared to other predators, they were able to mobilize available resources so that they might have an edge over their potential prey. How else could a human kill a deer or a buffalo, let alone an elephant, or whale?! Nevertheless, it was the law of the jungle that the fittest would survive. Food was scarce and difficult to obtain, and much energy had to be spent obtaining it. Their bodies were programmed to absorb as much food as possible and to store whatever was not immediately needed for use at a later stage when food may not be available.
