Just try to motivate them to exercise and listen to Dr's exercise is the best way to fight pd if they give in it wins

I can reach the same stage and get in a why bother mode. This has come with having had a stoke with too many residual issues, cancer, and now PD. Through this I have used motivational speakers, currently https://nickvujicic.com/. Listening to him reminds me of " I had no shoes and was sad till I met a man who had no feet"
