Former Scotland rugby player John Beattie has been investigating whether playing contact sports can lead to long-term brain damage. <br />In 2015, he made a documentary about the growing evidence which suggests that repeated head injury in such sports might lead to Chronic Traumatic Encephalopathy (CTE), a form of dementia. <br />Former players, among them John's rugby heroes, came forward to say that they could be among players affected. <br />One of the most poignant moments came when John Shaw was asked: "What do you think the future holds for you?". <br />After a few moments he replied: "That was one of my cut-out moments there". He says this is happens frequently and tries to answer the question again.
