Obsessive worrier and organiser Jon Richardson hosts a new comedy format where he attempts to analyse, assess and log every single one of his many, many worries.

To help him with this colossal task, Jon is joined each week in the studio by big name comedians plus a range of experts. Using a mix of film, funny studio set-pieces and archive Jon and his guests will explore exactly how severe each worry actually is before filing it accordingly in Jon's very own ‘Worriedness Index' – a high-tech digital log of every anxiety in existence.
