Answer:
I am the heart that does not beat. If cut, I bleed without blood. I can fly, but have no wings. I can float, but have no fins. I can sing, but have no mouth.
I went to the woods and got it, when i got it didn’t want it, looked for it, couldn’t find it so I took it home.
I am the red tongue of the earth, that buries cities.
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
I have a tongue, but do not talk. I follow close, but neither run nor walk. Coupled and hitched, but never married. You couldn't bear the load I've carried.
You use it between your head and your toes, the more it works the thinner it grows.
