Vicky,
In the UK, we don't have the same problems in health as you do in the USA. First, everyone over 60 gets free prescriptions. Then everyone has free healthcare under the National Health Service (NHS). Then the fortunate ones like myself have private healthcare for life as part of my pension.
However, I recognise what you are saying, I worked in Chicago for a couple of years, and did not even register with a doctor, due to the costs.
So if it causes problems for you over there, I am happy to drop it.
It just seemed a simple cheap way to get a pointer on genetic v environmental causes of PD
Best wishes
Ron
