I will review our current understanding of the evolution of M<8Msun stars from the pre main sequence to their end results as white dwarfs. Theoretical work on the helium flash may have put to rest one long-standing stellar evolution concern, while recent asteroseismic data from the Kepler and CoRoT satellites have found very slow rotation rates of the stellar helium core during both the red giant phase and those burning helium on the clump. These data challenge our understanding of angular momentum transfer within stars and raise new questions about the role of rotation on the fates of more massive stars.
