Martha, I read your message with great interest. I made a remark to Dick not long ago about the fact that maybe his PD was brought on by his unhibited use of pesticides around the house. He is forever spraying and dosing the grass trees foundation etc. He once even sprayed my office at work while I was in there working. I have no windows and no ventilation except the air conditioning and I was appalled he would spray poison around me in an enclosed area. He thought nothing of it. I told him I was sure he had been doing stuff like that for years, but to discontinue it immediatly around me and the children and grandchildren. They have to play on that grass and I didn't want it on their clothes and eventually in their mouths. If you see an offending bug step on it. Of course there is the problem of pesticides on our food too. Maybe there is a connection to all this. SuecgDick
