what I can't have I give to you

Take the blood that pools in my legs As long as your heart still beats Take the breath I can't ever catch As long as your lungs still move Take the strength my weary limbs lack As long as you learn to walk Take the salt I'm made to chase As long as you can still cry Take pieces of light from my eyes As long as you see the sun Take what I can't have, I don't mind As long as you're alive.
