David had confirmation of his diagnosis of Cowden Syndrome after his mum passed away with the same condition. David talks about isolation after being diagnosed, and the urge he felt to do something for the rare disease community. He now leads a group open to all men with rare disease, focused on mental health. Through this, he provides a platform for men to open up, or listen to others. 

The song David chose is Dream Baby Dream by Bruce Springsteen.
