This is Your Brain on Coffee

Sifu Slim is the pen name of Henry Kreuter, an author, wellness educator/speaker, lifelong amateur athlete, and leading proponent of “intentional physical activity.” As a writer, Sifu is an expert on sedentary living. His program of maintenance fitness, intentional physical activity, and downtime is the perfect antidote for the sedentary, over programmed world. He is the author of two books.

Sedentary Nation presents the challenges of the busy person living in the overprogrammed digital world as well as a plan to overcome this plague of modern convenience.

His second book chronicles the lives of some notable still-fit, former world-class athletes and retired elite military, and asks them, "Why are you—a small 10 percent of retired athletes—still maintaining your fitness while 90 percent of former world-class athletes have become mostly sedentary?"
