"Life Begins at 40" is a song by John Lennon. It was written in 1980, the year that both Lennon and Ringo Starr turned 40 years of age. Lennon recorded a demo of the song at his home, but it was not recorded at any of the sessions for his comeback album, Double Fantasy. Instead, he intended to give the song to Starr to record on his own forthcoming album, Can't Fight Lightning. The song's amiable country feel was well suited to Starr's singing style. After Lennon's murder in December 1980, those plans were shelved. However, Lennon's demo was eventually issued in 1998 on the John Lennon Anthology box set.
