According to this article by Lucy Wallis in the BBC, Chris Birch became gay after he suffered a stroke. Chris went from being a burly, beer-drinking, rugby-loving banker to become a hairdresser.
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.
"I was doing a forward roll down a grass bank one day and cut off the blood supply to my brain which caused a stroke to happen. It was from there, while I was recovering, that I realised I'd changed," says Birch, from Caerphilly.
"The Chris I knew had gone and a new Chris sort of came along. I came to the realisation that the stroke had turned me gay."
