Often people who live through the trauma are nostalgic when it's over. When I went back to Bosnia 20 years after the brutal civil war, even people who had been badly wounded told me they missed those times. They were missing their more courageous selves.

If hardship brought out the worst in people, the human race wouldn't have survived. Right after 9/11, for instance, the murder rate actually went down in New York City. In World War II during the Blitz, the civilians of London were bombed almost every night for six months, but psychiatric admissions declined.

There is some evidence that average wave heights are slowly rising, and that freak waves of eighty or ninety feet are becoming more common. Wave heights off the coast of England have risen an average of 25 percent over the past couple of decades, which converts to a twenty-foot increase in the highest waves over the next half century. One cause may be the tightening of environmental laws, which has reduced the amount of oil flushed into the oceans by oil tankers.

I don't think people would climb mountains or jump off bridges with parachutes or kayak Class V rapids if those things didn't offer the brief and horrible illusion of imminent death. They would just be complicated, time-consuming endeavors that we'd steer well clear of because they got in the way of real life.

Bad news is dramatic. It makes good TV. If there's a firefight on the same day that a school opens up, the media will show the firefight even though the school is way more important and will affect the community for much longer.

I was surprised how open and unguarded the military was. I expected more scrutiny, more supervision from command.

No matter how many people you kill, using a machine gun in battle is not a war crime because it does not cause unnecessary suffering; it simply performs its job horrifyingly well.
