Yes, and I hope I'm not taking too much time.
When you ask about “success”, I would ask what does success mean? If we think about it in terms of pursuing a cure, that's great--except that, as I always like to say, life is a sexually transmitted disease that ends in death. Everybody is going to die. So what does success mean for somebody living with Parkinson's now, where a cure really may not be an option?
I think that's really part of the answer to your question. Success for them isn't necessarily anything other than being cared for well, and what does that look like? How do you then make sure that the outcomes for someone coming to terms with their dying process, which is what it is, are as good as they could be, and what does that mean for them? Because that is where all of us are going.
What does success mean for those people?
