Lyric discussion by HeroShot 

This song is about getting old, and the decision old people are confronted with when they get old: “Should I give up?”

People you love / Will turn their backs on you / -- refers to how old people are neglected and seen as a burden.

You'll lose your hair / Your teeth / -- things that occur when someone gets older.

Your knife will fall out of its sheath / -- this is a very clever line, alluding to someone unable to get an erection; the sheath is the condom.

This is a very clever song, and one of my favorites.
