Thank you Ivan, I hope I can be even more useful on the list, from what I have learned from Dad's problems. He had other problems than PD, I will discuss them at a later date, to possibly help others avoid some problems. Due to Dad's legacy of humor, I hope to be able to distract those who need it, until the real cure comes along. I met more people in their late 80's in the last 2 days who would amaze you! Many still working productively. There is hope! AND, though he does work in mysterious ways, there is G-d! Hope you and your father are both doing ok. Ken B
