What do you do?
Do you immediately go into the white light and be judged to enter heaven or hell (like Ghost Whisperer)?
Hang around your family for a while and become a invisible helper?
Haunt you enemies?
Visit the places you never got around to visit while you were alive (Paris, Rio, Jamaica)?
Visit places where you would have got arrested while you were alive (Fort Knox, the Dallas Cowboys Cheerleaders locker room)?
