EXCLUSIVE: Tourette’s campaigner John Davidson is clarifying how his condition works following his outburst at the #BAFTAFilmAwards: “My tics have absolutely nothing to do with what I think, feel or believe,” he told Variety. “It’s an involuntary neurological misfire. My tics are not an intention, not a choice and not a reflection of my values… What you hear me shouting is literally the last thing in the world I believe; it is the opposite of what I believe.”
