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.

I think objectivity is like this strange myth that people think you're supposed to achieve, but actually, the dirty little secret is that it's not attainable any more than pure justice is attainable by the courts.

Ironically, though our society of affluence brings safety and stability, it doesn't bring psychological health. As wealth goes up, suicide and depression rates tend to go up. I read one study that compared women in North America with women in Nigeria, and the group with the highest rates of depression was urban North American women, which is the wealthiest. Now, there are obviously huge stresses that come with poverty, but the poorer the society, the more collaborative people have to be.

It's fun to have money, but the more money I get, the less interesting it becomes. If you don't have very much, you have to think about it. If you are starving, you become interested in food. If you are struggling to pay the bills, money becomes tragically important.

The negative effects of combat were nightmares, and I'd get jumpy around certain noises and stuff, but you'd have that after a car accident or a bad divorce. Life's filled with trauma. You don't need to go to war to find it it's going to find you. We all deal with it, and the effects go away after awhile. At least they did for me.

I decided to start a medical training program for freelancers, only freelancers. They're the ones who are doing most of the combat reporting. They're taking most of the risks. They're absorbing most of the casualties. And they're the most underserved and under-resourced of everyone in the entire news business.

During the air war of 1944, a four-man combat crew on a B-17 bomber took a vow to never abandon one another no matter how desperate the situation. The aircraft was hit by flak during a mission and went into a terminal dive, and the pilot ordered everyone to bail out. The top turret gunner obeyed the order, but the ball turret gunner discovered that a piece of flak had jammed his turret and he could not get out. The other three men in his pact could have bailed out with the parachutes, but they stayed with him until the plan hit the ground and exploded. They all died.
