Michael J. Fox has been living with Parkinson's disease since the early '90s after discovering his condition on the set of "Doc Hollywood." He was given 10 years to live if he was lucky, but 23 years later he's still with us. Fox's Foundation has $450 million for Parkinson's research and he managed to surprise everyone at a recent concert playing two classic songs from "Back To The Future."

He's been known to play guitar, but we haven't seen him play in years. And with a crippling disease like Parkinson's, it's almost impossible to perform even daily tasks, such as holding a cup still. He shocked and awed folks attending a Coldplay concert recently and played two classic songs from the "Back To The Future" soundtrack --- watch as he shreds into "Johnny B. Goode."

Michael J. Fox has always been one of my favorite actors, but to see him still making a difference and making people smile is the highlight of my day.
