It is hard for me to live, but easy to die. I am only present when I am not given away. Many people know about me but not what I am. You can keep me, but it is hard. What am I?
A man is in a room with no windows, no doors, no doorway. There is only a table and a saw. The walls and ceiling are too thick to saw through. How does he escape?
He cuts the table in half, and puts it together. Two halves make a whole / hole, and he escapes through the hole!
