Former England scrum-half Ben Youngs became emotional while discussing head injury concerns with Lewis Moody, who has been diagnosed with motor neurone disease. Youngs explores these issues in his documentary "Ben Youngs Investigates: How Safe Is Rugby?" Despite no scientific evidence linking MND to concussions, Youngs questions whether the sport is truly safe for players at all levels. The emotional interviews reveal the personal toll these concerns take on former players.

Youngs reveals how rugby's approach to head injuries evolved dramatically during his career from 2007 to 2025. Former teammate Anthony Watson admitted cheating the concussion test, while Youngs himself admitted he wouldn't have left a World Cup final with symptoms. Steve Thompson, now living with early onset dementia, joined a concussion lawsuit against rugby authorities and stated he would not let his children play the game, exposing the dangerous culture that once existed.

World Rugby has implemented significant safety measures including smart mouthguards and independent doctors overseeing head injury assessments. Youngs underwent a brain test himself and was relieved when results came back clear. He advocates for brain testing to become standard for former players, particularly those in high-impact positions. The documentary shows how the sport has progressed in safety protocols, but acknowledges that rugby remains a contact sport with inherent risks that require ongoing attention.
