Lucy Wallis tells the story of a man whose personality changed after a stroke: “Chris Birch struggles to remember or identify with his old self. He used to be a 19-stone, beer-swilling, party-loving rugby fan from the Welsh valleys, the life and soul of a party. He worked in a bank and loved sport and motorbikes. After a freak accident in 2011, he says he underwent a big change to his personality. He believes that he has gone from being straight to gay.” [BBC]
