NEW YORK – MAY 24: Moira Sauvane works as a cancer researcher at Columbia University May 24, 2005 in New York City. Javier Garcia, an Argentinian-American and a third-year psychiatric resident, and Moira Sauvane, an Argentinian and a post doctoral cancer researcher, are among the best tango dancing couples in the world. For the last three years they danced the tango almost every evening, three to four hours a night, somewhere in New York City where they now live. Their tango is unique, in that they come together in a passionate dance dialogue where they exchange lead, in a constant form of improvisation. Their relationship is also unique. Moira is married to another man. (Photo by David Turnley/Getty Images)
