Answer:
I am longer than a decade and shorter than a millennium
I will go within you and destroy you. Only because you wanted me too
You shoot me but I don't die. You hang me but I don't die. What am I?
I can be sweet or sour. I do not rhyme with any other word
I am of several different kinds, but the one you pick doesn't do its job. What am I?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
