Today is the first of April. I know. It seems like a good day for joking. But this is no joke. About ten percent of the people diagnosed with Parkinson's each year are under the age of fifty. Now fifty can be a good age, full of promise. When Bilbo Baggins,the hobbit, turned fifty, he set out on an adventure with twelve dwarves and a wizard. When his nephew, Frodo, turned fifty he took the One Ring to Mordor to destroy it. When I turn fifty in January, I do not think I will be able to set off on any journeys but, if I am lucky, and if I stick to it, I hope I will be walking to the Clinton Community Nature Center; it is only 1/4 mile away. Once there, I can walk on the Natchez Trace, a footpath that has been followed for centuries. For a person living with Parkinson's, fifty is still young. Exercise is the only thing known to halt or reverse its progression. What if, during April, each person who can walk invited someone to join them for a walk? They could enjoy being enjoy how being outside makes them feel, and improve their health. Maybe two of them might even brainstorm up a cure for Parkinson's.
