Natacha Poberaj and Julio Duplaa are seen behind the curtains as they dance the tango during a show on the fourth floor of the Borda Hospital on August 26, 2009. A few months ago some were too shy to talk and others could barely keep their balance when they walked. Today, they embrace their partners cheek-to-cheek, gliding and pausing across the floor to the mournful chords of a traditional accordion. (REUTERS/Marcos Brindicci) #
