 Now, there are a lot of reasons. Just being old, it doesn't have to be Parkinson's to have that weird shuffling gait, to have that weird stiffness, to have that old man. He could be terrified of tripping. They put him in special shoes. Remember, I'll be curious to know if those special shoes have anything to do with Parkinson's disease as well. The possibilities are endless. The only possibility that isn't being entertained because it's the only possibility.
