Steve and Andrew offer beer and chips to bribe Matt into an interview. Matt shares all his secrets about running the Kepler and Barkley Marathons. Topics also cover genetics of obesity, the difference between sugar and heroin, brain tumours, running on drugs, and more about drugs and having a degree in chemistry. Not only does this look like an episode of Breaking Bad we also get lots of stories about quitting, not quitting, passing Mr Muir although not mentioning getting passed by Ms Muir singing 'Bodys Hit the Floor', running for fun and lots of other numbers.
