Seen that before, very interesting to watch. Never come accross anyone with tourettes personally but if I do, I will certainly know how to react a lot better, or in fact a lot less thanks to that program. Can't help but feely really sorry for these people but it's good that they get on with their lives and that the recognition and understanding of the disease is growing.
Can't help but laugh at the bit where the bloke is walking his dog though! Poor dog doesn't know what to do!
