Mat Barlow, a firefighter, describes his battle with PTSD, triggered by an incident that took place whilst he was driving a fire engine. He describes some of the most tragic symptoms he’s experienced that affected his relationships, his family and his work. Imagine if we could have prevented those symptoms? He’s joined by Dr Jen Wild, a researcher who’s aiming to do just that. She talks us through her innovative programme that’s preventing mental health problems in emergency workers.
