Yes I can see that it may have been an insight to some, if my dad didn't have Parkinsons I probably would have watched it and not thought a lot more about it.
My dad lives on his own and does the best he can, but added to his Parkinsons is his terrible grief of loosing his "best Pal " my mum, who died 2 yrs ago. I really thought he would have died with a brokwn heart.
I can only say, he must be made of strong stuff! which that generation were.
I had an Uncle who died about 20 yrs ago with Parkinsons, he once asked my dad to "help him die" his brain was still there but he was just curled up in a bed.
Since them some prgress with medication has come along, but very little.
