Actress Mia Farrow is ending her 12-day fast protesting the humanitarian crisis in Darfur and is leaving billionaire Richard Branson to carry on the cause. Farrow’s doctor said she must stop the liquid fast for health reasons. “I am fortunate. The women, children, and men I am fasting for do not have this option,” 64-year-old Farrow told Entertainment Tonight. Branson, the mogul behind the Virgin brand, said he visited Darfur over a year ago and was “horrified” by the conditions there. He plans to fast three days for the cause.
