Answer:
What is harder to catch the faster you run?
What always ends everything?
What is deaf, dumb, and blind, but always tells the truth?
I have a hundred legs but cannot stand a long neck but no head and I eat the maid's life. What am I?
I dig out tiny caves and store gold and silver in them. I also build bridges of silver and make crowns of gold. Sooner or later everybody needs my help yet many people are afraid to let me help them.
Break me and I am better immediately set and harder to be broken again.
