Answer:
I donβt forget!
I make you weak at the worst of all times. I keep you safe I keep you fine. I make your hands sweat and your heart grow cold. I visit the weak but seldom the bold.
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
There is one in every corner and two in every room.
I break down buildings, I crumble mountains but you can't see me. 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.
