The Rev. Billy Graham is back on his feet, six days after being hospitalized following a fall. The 80-year-old evangelist was released from the Mayo Clinic Jacksonville (FL) on Wednesday. Graham, who was not seriously injured in the fall, also received follow-up care for previous eye surgery during his stay, clinic spokeswoman Carol Chaffin said. Graham, who suffers from Parkinson’s disease, had previously been treated at the Mayo Clinic in Minnesota.
