Answer:
I moan I groan I chase after you. I never seem to rest. Timeβs up for you.
The more of this there is the less you see. What is it?
I make everyone blind. You can't see me but I will always come back for you. What am I?
In my life I must bare, my bloodline I must share. What am I?
I can swim but never get wet. I can run but never get tired. I follow you everywhere but never say a word.
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.
