Yeah I'm sixty-three years old
You know look at you you're
Just a baby, you're twenty-two
Jack White is 36 himself, at the time of this song, which is interesting since 63 is 36 backwards.
The song is obviously about an older man (perhaps Jack himself?) who is in a relationship with a younger woman and doesn’t know whether it should continue or not.
There was a rumor that his divorce was because he cheated on his wife with a member of the Black Belles, she was 21 at the time, making her currently 22. He created her band on his label.
