Actor Ryan Reynolds, who sits on the Board of Directors of The Michael J. Fox Foundation for Parkinson’s Research, is challenging his fans and the general public to get involved in helping to speed a cure for Parkinson’s by “liking” the Foundation’s Facebook page (facebook.com/michaeljfoxfoundation). If the Foundation reaches 100,000 Facebook fans as part of its national Parkinson’s Awareness Month campaign, Reynolds will add $10,000 to his cumulative giving to the Foundation.
