Most every population can be statistically described along a bell shaped curve graph. The majority of a population, about 68%, occupies the center portion. The remaining 32% is split equally on the edges. When describing human emotion, the left edge is composed of people who are cautious. The right edge is composed of people who engage in life threatening activities. Aviators tend to occupy that right edge. One piece of anecdotal evidence supporting this is that almost all conversations, acronyms, stories, and training about flying include or begin with the word “safety”. Most people don’t have to be reminded to avoid life threatening behaviors. As a matter of routine, aviators do.
