Dash Mihok

The ‘Deep Water’ star has worked his way to a successful career in acting in spite of his hereditary condition that developed at the age of 10 during his karate training.

He said: "We were trying to be still, but I had an urge to whip my hair around my head. I couldn't stop doing it."

Sadlt, the actor hates going to the cinema due to his tics.

He said: "You're born with a problem that draws attention when that's the last thing you want.

"What hurts most is that you're doing things that can take away from somebody else's experience — like watching a movie. It's a sickening feeling sometimes."
