Today we are in a healthcare crisis. All around the industrialized world people are struggling with declining health. From childhood obesity to the multiple health-related needs and concerns of an aging population, millions need help understanding, managing, or even reversing their maladies. Hospitals are essential of course, but most are set up for episodic care, not long-term disease management or continuous health improvement. So healthcare organizations, civic leaders, church leaders, and philanthropic groups wonder what can be done to help.
