A piece taken from that song/lyric
"Don’t feel guilty if you don’t know what you want to do with your
life…the most interesting people I know didn’t know at 22 what they
wanted to do with their lives, some of the most interesting 40 year
olds I know still don’t. Get plenty of calcium. Be kind to your knees, you’ll miss them when they’re gone. Maybe you’ll marry, maybe you won’t, maybe you’ll have children,maybe
you won’t, maybe you’ll divorce at 40, maybe you’ll dance the funky
chicken on your 75th wedding anniversary…"
I think it's rather appropriate :)
