Blimey! That's wonderful! You brought tear to my eye dude!
My grandmother died of Parkinson's 20 odd years ago. My great uncle about 10 years before that. It's an incredibly viscous disease that takes away people's dignity. I would have loved to have seen them try this but their time was too early.
RIP
Honestly? It makes me tear every time, too... but I think about my neighbor we met at the beach house in Ogunquit, ME, back in the 90s, that has/had (?) a pretty severe case of MS, like always in a chair or wheelchair-type MS, and how I'd hook her up with local bud, and she'd just get up and walk around! And look and talk soooo much better and seem so much happier (of course).... her pop, a Texas Supreme Court Judge actually owned the tiny cabin, too, and she'd come up now and then with only her hubby and we'd cross paths... haven't seen them in a good 20 years, or so... hope they are well.
Edit: my father in-law basically died of atypical Parkinson's (no tremors, but muscle issues etc) from being a (phd) chemist for Sprague Electric out on the Deerfield River in North Adams, MA, (went to Williams w/a scholarship, one town over) and being exposed to very specific nasty chemicals in the days before OSHA... he also got laid-off early in the 80s... and wasn't diagnosed until the early 00s.... very sad.
