good question, carey...
I have seen alot of Parkies, I have met more women left -then men -
in "The Champion Video" all the men remained married - and except for one -
all the women went through divorce - I t has been a tough life since -
but actually I prefer it on my own.
my theory -
if the husband is a PD patient the wife will stay if he has money or
the better thought would be if she truly loved him,

the husband usually if healthy will run from it / and leave the PDwife and be replaced with a newer healthier model,

the only one I can actually think of is "Mort Kondarke stayed for Milly,
Milly was very very ill when I met her, her face was frozen -yet she could speak with her eyes, her eyes filled with tears - when her Dr. chase introduced me to her, and I told her not to worry - I was fine...

soooooooo many such people I have met who have lived and died with this plague.
