South African President Jacob Zuma, center, leaves after visiting the Mediclinic Heart Hospital where former South African President Nelson Mandela is being treated in Pretoria, South Africa Wednesday, July 10, 2013. The Nelson Mandela Foundation is hoping that volunteers around the world will donate 67 minutes of their time when South Africa's former president turns 95 next week, in reflection of what the foundation says is the more than 67 years Mandela spent serving his community, his country and the world.
