Keep Your Heart Young, by Brandi Carlile

So take a picture of the one you love and put it in a locket
Go dig up your time capsule and the blueprints for your rocket
Keep in touch on a fake CB,  that same old tic-tac box
Pack your snowballs a little less tight
but in the middle still put rocks

And keep your heart young
Don’t go growing old before your time has come
You can’t take back what you have done
You gotta keep your heart young

You gotta keep your heart young
Sometimes you don’t die quick
Just like you wished you’d done
‘Though love is a loaded gun
You’ve gotta keep your heart young
You can’t take back what you have done
You gotta keep your heart young
