GOOD RIDDLES

What goes up but never comes down?

Always in you, Sometimes on you;

If I surround you, I can kill you.

What am I? 

I make two people out of one.  What am I?

I have lakes but no water,

No cars but I have streets;

Many places and borders,

But I'm in one piece.

What am I?

One day, the police found a man dead inside a hut. In his left hand, he's holding a gun. In his right hand, he has a recording. When the recording is played, the police hear the man talking about how horrible life is and how he wants it to end. The recording ends with a gunshot. The police are about to call it a suicide until you point out a very important clue. What is it?

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

What 4-letter word can be written forward, backward or upside down, and can still be read from left to right?

Look in my face, I am somebody; Look in my back, I am nobody.

What am I?

Until I am measured I am not known, Yet how you miss me when I have flown.  What Am I?

How can you leave a room with two legs and return with six legs
