I have spent a lot of my career on the road, sometimes in arduous situations. I have peeled leeches off my feet after going barefoot on a mountain in Thailand. I have suffered near frostbite by exposing my bare hand to minus-30 degree weather in the Arctic. I became exceptionally agitated when I temporarily lost sight of my Arabic-speaking driver at the Syrian border last year. And five years ago today, I ran the Boston Marathon.
