FILE - In this Wednesday, July 18, 2012 file photo, former South African President Nelson Mandela celebrates his birthday with family in Qunu, South Africa. The emotional pain and practical demands facing Nelson Mandela's family are universal: confronting the final days of an elderly loved one. There are no rules for how or when the end may arrive. Mandela's status as a respected global figure only complicates the situation, doctors and end-of-life experts say. (AP Photo/Schalk van Zuydam, File)
