On a US radio show they hosted called The Pursuit of Happiness, John Littig and Lynne Rosen urged listeners to embrace spontaneity.

"So much about life is about impulse," Littig said on a broadcast this year on an FM station in New York, WBAI. "It's about doing it right now."

A shocking decision the couple made together appeared more methodical: Police say they killed themselves side by side as part of a suicide pact.

The bodies of Littig, 47, and Rosen, 45 were discovered on Wednesday on a couch in the couple's brownstone in Brooklyn.
