Really interesting video on the effects of concussions in contact sports. Featured in the video from One News New Zealand is former All Black scrum-half Steve Devine discussing how repetitive cases of concussions had an effect not only on his family life, But also his own mental health. After this video you'll have a new-found respect for people who play the game, whether its professionally or in the amateur game.
