How does social inequality affect people's health?  Two health activists, Desiree Hellegers and Tricia Tillman, talk with Bill Resnick.  They are part of a major conference on Friday, April 18 at  Washington State University in Vancouver.  It's called "Health Disparities and Inequities: Mobilizing a Regional  Response,"  and it's open to the public.  For information, go here.
