(Pretoria)  --  Former South African President Nelson Mandela is now reportedly on life support.  The 94-year-old freedom icon is being hospitalized in critical condition at a private facility in the capital of Pretoria.  The country's first black president has been hospitalized several times over the past year with lung complications.  Mandela's lung troubles date back to the tuberculosis he contracted during his 27-year imprisonment under South Africa's apartheid system.
