Hi, I joined the list a few weeks ago and am still learning about sending mail etc., so I hope this makes it. My father was diagnosed with PD 3-4 years ago. Unfortunaltely I don't see much of him as we live in different countries. My main motivation for joining the group is to learn more about PD and also to send on any useful tips I read here back to him. I found the discussion about a possible relationship between PD and surgery interesting as my father has had numerous operations in the the last 10 years or so. Annie Mills
