Minnie Miller spoke freely to the man standing beside her about the preponderance of high blood pressure in her family. She also inquired about heart disease. But Miller was not talking to her doctor. Instead, she shared her concerns with her barber. Miller was among many customers around the city yesterday who not only received haircuts and styles from their barbers, but health advice and information too, as a part of the third annual "Take a Health Professional to the People Day" sponsored by the University of Pittsburgh Center for Minority Health.
