Answer:
If you break me, I do not stop working. If you touch me, I may be snared. If you lose me, nothing will matter.
I grow for a surface, even if you cut me. I continue to grow even after death.
I can be quick and then I'm deadly, I am a rock, shell and bone medley. If I was made into a man, I'd make people dream, I gather in my millions By ocean, sea and stream.
I am never quite what I appear to be. Straight-forward I seem, but it's only skin deep. For mystery most often lies beneath my simple speech. Sharpen your wits, open your eyes, look beyond my exteriors, read me backwards, forwards, upside down. Think and answer the question...
Alive without breath, As cold as death, Clad in mail never clinking, Never thirsty, ever drinking
