Are all gay people just “born this way”? Most apparently are. But a rare few, including the young man in the documentary above, find their sexual orientation changed when their brains are suddenly altered by a cerebrovascular accident…a stroke. Chris Birch has lost large chunks of his memory, and with it, his former self — a heterosexual, chubby, “chavvy”, rugby-playing bank clerk with a lengthy string of girlfriends. Now a hairdresser making plans to marry his boyfriend, he’s trying to piece together a coherent picture of who he was, and how he became the person he is. He’s also trying to reconnect with old friends and family from whom he became alienated as a result of his stroke. He is certain that the stroke changed his entire sexual orientation, as well as wiping out his old personality and the memories that came with it. And since being gay is indeed a state of brain, it turns out that he is right. He is literally a different person since his stroke, and it is all because of a fundamental change in the structures of his brain.
