A murderer is condemned to death. He has to choose among three rooms. The first is full of raging fires, the second is full of assassins with loaded guns, and the third is full of lions that haven't eaten in 3 years. Which room is safest for him?
The third one. Lions that haven’t eaten in three years are dead.
What is wider than life itself
Longer than forever
So simple it's complicated
Travels but never leaves the spot
Puts others in danger but no one gets hurt
And reaches to worlds unknown?
