If I were not a writer, I would spend more time doing the things that I am already doing, which include doing research in physics, teaching, and running a nonprofit organization with a mission to empower women in Cambodia.

Yet, only years after the Nazi-era, millions were sent to their deaths in places such as Cambodia, Bosnia and Rwanda, and the world once again took too long to act.

There are a lot of recent pics of me rocking silk strings of beads. They're made by survivors of the sex trade in Cambodia who were rescued by one of the organizations I support.

The fact that you had disruptions in the peace process was not only in Rwanda. We had the same problem in Cambodia, we had the same problem in Mozambique, we had the same problem in Salvador.

I look and there's our boy from Vietnam and our daughter from Ethiopia, and our girl was born in Namibia, and our son is from Cambodia, and they're brothers and sisters, man. They're brothers and sisters and it's a sight for elation.

My second TV assignment ever was to go to Cambodia to look at the state of the country in the dying days of the Khmer Rouge. I was naive, awkward, and not very good at writing to pictures.
