Jamie wants to talk about barriers both mental and physical ones that prevents people from doing things they want to do. He describes his barriers and together Gill and Jamie work out what he actually does that allows him to remove any barriers and how that can be duplicated to removing other barriers.
As is usual with Gill and Jamie they then somehow end up talking about buying friends presents and Gill shares what she did a few years ago to overcome that barrier and the impact it had on others.
