This chemical theory is interesting. I "played" in pellet fertilizers like in a sandbox, and helped spray herbicides and pesticides while riding on the back of the tractor on our farm when I was a child. Most recently, we moved to Missouri and used a lot of bug spray and "bombs" over the last 15 years. Also, while staying on my Dad's ranch for several months, he had the timber sprayed, right over our heads by airplane. All the hardwood trees died. Strange, this may have some bearing on the PD. Thanks to those of you who wrote to me about the Christmas issues, good, useful info. I wish I had time to write each of you back. Thanks, Monica dx. @ 50 now 51. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
