Nelson Mandela's been having a rough time lately. The 94-year-old was admitted to the hospital early Friday morning for the recurrence of a lung infection—his fifth hospitalization in the past two years. The former South African president and anti-apartheid leader, is in "serious but stable condition,” according to a presidential spokesman. Mandela's lung issues are nothing new, and it is believed that he suffered permanent respiratory damage working in prison quarries during his 27-year sentence. But there is positive news: the spokesperson also said that Mandela is able to breathe on his own. Here's hoping for a speedy recovery.
