This is the video for Rjd2's "Work It Out" from 'The Third Hand' (XL Recordings).
The vid features Bill Shannon who was born with a degenerative hip condition. His legs cannot carry his own weight and so he has lived a life on crutches.
He has developed a new way of moving through life on his skateboard and the crutches. Though this may look like a recreational hobby or a debilitation, it is simply how Bill maneuvers throughout the day.
