Graciela Anton (L) and Manolo dance the tango during a show on the fourth floor of the Borda Hospital, Buenos Aires' largest psychiatric hospital, as patients, doctors and nurses watch in Buenos Aires 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. Doctors as far afield as Italy and Australia are using Argentina's world famous tango to treat problems ranging from Alzheimer's and Parkinson's disease to phobias and marital breakdowns.
