Although this leaflet begins by exaggerating the risks of drinking even small amounts of alcohol, it morphs into a treatise on social and human evolution. Bishop grew up at a time when physical fitness as an ideal had spread from Europe to the United States. This concept may have influenced his belief that the human body had originally evolved for survival in the wilderness and still retained its instincts to eat meat (and caffeine). At a time when most jobs involved manual labor, people still required meat to maintain their bodies. But in this leaflet Bishop argues that humankind has entered a new era, one in which most people do not have physically demanding jobs and in which the instinct to consume meat and caffeine is an anachronism. Meat eating causes obesity, which leads to nervousness and depression, which leads to alcohol abuse as a way of drowning these psychological troubles. And so Bishop advocated vegetarianism to prevent alcoholism.
