President of Yale University

We leave together. You leave Yale College after four years; I leave the Yale Presidency after twenty. I find myself thinking about a Grateful Dead song written in 1970, the year I came to Yale as a graduate student. You know the words: "Lately it occurs to me, what a long, strange trip it's been." It's been a long trip, but, for us, more wonderful than strange.

Exonerated from death row in 2002

My trial took less than a week. I was sentenced to death. I spent nearly 18 years on death row, a traumatic and heartbreaking time for me and my family. I never stopped fighting for my freedom.

I have been involved in research in this area for 17 years, since shortly after BRCA1 and BRCA2 were discovered, and I have no idea what I would do if I were a woman faced with this decision. The diagnosis of a mutation is just words on paper, but the risks they foreshadow are very real.

Your chance of winning the lottery on a single ticket is one in 175 million. That seems tiny, and it is. In fact, it's so small that it is difficult for us to grasp.

The good news: The Office has a legacy as large as its heart (and Dwight's head). It'll never really be gone, because it's changed, well, everything. It's inside us now. That's what she said.
