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

Belated Guardian Angel
Walking down the street, a man hears a voice: Stop! If you take one more step, a brick will fall down and kill you.
The man stopped; a big brick fell in front of him. The astonished man continued walking to the cross walk.
The voice shouted, Stop! If you take one more step, a car will run over you and you will die.
The man stood still; a car came careening around the corner, barely missing him.
Where are you? the man asked. Who are you?
I am your guardian angel, the voice answered.
Oh yeah? the man asked. Where the hell were you when I got married last week?
