They do not possess flesh or feathers or scales or bone
But still, they are blessed with fingers and thumbs of their own.

I am white when I am dirty, and black when I am clean. What am I?

Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I?

John was piloting a plane behind a car but was never able to overtake it. Why?

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What is it?

Can you write down eight eights so that they add up to one thousand?

Pronounced as one letter,
And written with three,
Two letters there are,
And two only in me.
I am double, I am single,
I am black blue and grey,
I am read from both ends,
And the same either way.

The more you take me, the more you leave me behind.
Who Am I?

When I get multiplied by any number, the sum of the figures in the product is always me. What am I?
