text:  So boxing, I'm glad you said that because we're going to definitely talk about physical activity. But what happens with Parkinson's is that it robs your ability for automatic movement, everything automatic, eye blinking, swallowing, even automatic posture. So, for example, if I am standing on a hillside that's slanted, I don't think about it automatically. I'll shift my center of gravity so I don't fall down the hill. If you have progressed Parkinson's, that automatic pilot may not be working for you if you're not getting the dopamine right.
