parkinson's awareness

Being newly diagnosed, I was far from suffering what would become in future years, one of the most annoying debilitating symptoms of Parkinson's. At the time, unfamiliar with the term 'on' and 'off' I asked for clarification of this phrase.
I've heard from people accused of being drunk, refused service in supermarkets, ignored by taxi drivers, and even arrested by police at the Olympics for not smiling (lack of facial expression can be one of the signs of the condition). This simply has to change.
