The inspiration for a photo book can come from anything. For photographer Joe Madsen, it was cholesterol. When his doctor told him his cholesterol was too high he decided to eat better and walk more. But he needed extra motivation, so Joe brought his camera with him. Bloodwork is the visual story of how an effort to make his body better led to a better body of work. This 62 page soft cover book is a collection of street photography from around the world.
