 The title is derived from a phrase from the poem "A Shropshire Lad"  by A.E. Housman (qv): "But since the man that runs away / lives to  die another day". In the movie, James Bond says to Gustav Graves,  "So you live to die another day." This is a reference to the start  of the movie when it was believed that the villain under his  alternate persona had been killed.
