Just finished listening to this TJ. Thanks that was awsome. I posted a link to this on Facebook because I get questions from family members all the time and I think they would listen to what a doctor has to say more than what I have to say. I'm trying to appeal to them by ethos and logos (using dr marks credibility and authority as a dr and then also his reasoning).
His being a doctor is incredibly helpful and why this interview is so important to our sport, but also that he is bridging our message to the shod running community.
