How much can we blame DNA for our depression and anxiety? Is something about our mental health pre-written into our genetic code? How much trauma carries over from one generation to the next? How should we think about epi-genetics? These were 4 of the 20 questions I brought to Dr. Francis Collins, the guy who let the team that mapped the human genome. There’s two things I want to say about this episode: I learned so much just studying for the interview and every minute I spent with Francis Collins was a total joy. He is a very special person — direct, deeply informed (maybe moreso on this topic than anyone else on Earth) and delightful. I am so excited to put his guy in your ear — a happy, loving man filled with purpose and eager to share what he knows (and doesn’t) for the greater good. And he laughs easily and a lot. So, I was getting hits of my dad the whole time. A heavenly experience that comes through in every minute of the conversation. Enjoy.
