This is a presentation recorded in Breckenridge, Colorado, February 2017 and published in March 2017. Personally, I had the privalage to listen to a similar presentation in a small hotel in Skipton in the 2016 shortly after he was awarded NHS Innovator of the Year - the first GP to achieve that award.
