People who do really dangerous tasks can't afford to sit around and discuss the merits of what they're doing.

Well, you got to remember, bin Laden killed 3,000 Americans and, in some ways, he and his ideology killed tens of thousands of his fellow Muslims, including Pakistanis. I understand that that was provocative and complicated for Pakistan, but only if you accept the idea that he was an acceptable member of Pakistani society.

The attacks of 9/11 came out of Afghanistan. It was a failed state, a rogue nation. That's why al Qaeda was there in the first place.

One interesting thing I found was that if you take an affluent modern society and collapse it during a crisis, like a war or a natural disaster, people begin relating in a more ancient, organic way. They're functioning in small interdependent groups and putting others first. And another irony is that even in terrible times, cooperating makes people feel good.

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.

I hope I get married one day.

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.
