Answer:
In my life I must bare, my bloodline I must share. What am I?
I twist and turn and leaves a loop
I can be written, I can be spoken, I can be exposed, I can be broken. What am I?

I am always around you but often forgotten. I am pure and clean most time but occasionally rotten.
I am rarely touched but often held. If you are smart you'll use me well. What am I?
