Peter Dunlap-Shohl's   Off&On: The Alaska Parkison's Rag  has a pop quiz on Parkinson's disease.  He tells how he wrote it to avoid admitting to his PD support group that he hadn't prepared to lead the meeting, but that it worked well. 

Peter was a political cartoonist for the Anchorage Daily News and he applies his cartoonist ironic whimsy to look at his Parkinson's as an adventure (generally not pleasant) and I think his blog is one of the best in Alaska. 

You can get the answer to the question and a bunch more at his blog.  And see how learning can be fun.  He has a much, much lighter touch than I have here and gets us to think about this disease differently than I've ever seen.
