Go back 200 or so generations and meet your hunter- gatherer ancestors. Try as you might those genes won't go away. Why do you think golf is so popluar? Men still want to wield a club or spear and be victorious in the hunt. As long as man has food and shelter he can keep his primal nature in check. Governments know what will happen if it's citizens run out of food, beer and cigarettes,too. New Orleans ( Katrina) was a window to our past human nature.
