I shot this at a noisy convention in NYC called the seed experience. If you can focus on what he is saying you may learn something about gut flora.
I got to sit down with Rich Roll only a few days after reading his book. It was so surreal to finish the last page of Finding Ultra and say, I hope I meet him some day. The next weekend I ran into him in NYC and he gave a one on one interview. My tripod dropped and I was so focused on him that it did not turn out so well but his info is great for people starting a new fitness routine or running.
