Due to their strong sense of purpose, U.S. Troops in Afghanistan are afflicted with few discipline problems, only a few minor medical complaints, and only one minor case of battle fatigue (far fewer than is statistically likely), and unusually, none of the 4,000 U.S. soldiers in Afghanistan has been sent home for psychiatric reasons. The experts credit good leadership as well as a sense of purpose for significantly reducing stress, which leads to such problems.

Ah, for a sense of purpose.
