Answer:
People need me yet they give me away every day.
I wonβt break if you throw me off from the highest building but I will break if you place me in the ocean.
I am very easy to get into,but it is hard to get out of me. What am I?
I am round. I have only one line. Circle is not my name indeed. What am I?
