1) Pumping blood and oxygen A machine mortal as all men That's what your heart's for That's what your heart's for 2) It's the hand that shapes your moods It's so strong but it so easily wounds That's what your heart's for That's what your heart's for Bridge 1: Sometimes that pulse is strong Sometimes there's nothing –where's it gone? Though all joy and pain It takes the strain and carries on 3) Hidden by a shield of bone Wishing it was not so all alone That's what your heart's for That's what your heart's for 4) Helping us in times of stress Beating fast as we undress That's what your heart's for That's what your heart's for Bridge 2: Sometimes I find when I Take a look inside that it's gone Then you look my way And it's back to stay where it belongs 5) Built to a simple plan And yet so hard to understand That's what your heart's for That's what your heart's for 6) Once so bright and bold Now dull and hard as we grow old That's what your heart's for That's what your heart's for Bridge 3: Sometimes that pulse is strong Sometimes there's nothing –where's it gone? Though all joy and pain It takes the strain and carries on 7) Now the ravages of time And fading memories gone by That's what your heart's for That's what your heart's for 8) Stained forever red and Feeling things that can't be said That's what your heart's for That's what your heart's for That's what your heart's for...
