Jean,

Exercise does work but as we all know, nature of science is to prove any hypothesis. The recent results of the trial with 26 people confirms the first trial that was held with 12 people, that confirms the serendipitous results of Jay's ride across Iowa 10 years ago. Now they are starting a study with 100 people, which happens to be a magic number in scientific research. It's hard to wait, both for the trials and for the outcomes.

In the meantime, many YMCAs and exercise centers across the country are starting Pedaling for Parkinson's programs. If there is not one in your area, contact your local YMCA or don't hesitate to contact me with a private message and I'll see if I can help.
