To be brutally honest, for much of that time, I was the only person in the world with Parkinson's. Of course, I mean that in the abstract. I had become acutely aware of people around me who appears to have the symptoms of Parkinson's disease, but as long as they didn't identify with me, I was in no rush to identify with them. My situation allowed, if not complete denial, at least a thick padding of insulation.
