Hi Barbara, just read the birthday news. Happy Birthday to the PARKINSN List and congratulations to its originator and driving force. The Parkinsn Network is, without a doubt, of immeasurable benefit to all who subscribe to it. Even if I don't actively write as often as I perhaps should, I look forward every day to reading the correspondence. The wealth of information provided by the participants is enormous and often unobtainable anywhere else. So again, congratulations to you and all subscribers to the Parkinsn Network.
