I can run swiftly and silent...
I can run swiftly and silently when you want me to stay still, I can move slowly and cautiously and am yours to fill. You look at me often and yet you always forget me, I am the most feared killer, yet you can't live without me. Sometimes you have me for all to spare, Yet when you need me, I am not there. You can waste me, or cherish me, you choose the track, But once you're done you can never get me back. What is it?Correct answers: 37
