The Tourette Syndrome Foundation of Canada wanted people to really understand the frustration, randomness and judgement that comes with Tourette. So they launched Surrender Your Say, a campaign where people could give up control of their Twitter handle and have Tourette tics tweeted randomly into their feed. It was controversial. It had never been done before. And for a day, thousands of people felt what it was like to have Tourette Syndrome, in front of millions and millions of followers.
