What do you most often think about before you fall asleep?

Mental checklist of what I should get done once I wake up.

Stephen Colbert is interviewing the guy who has the most interesting books in his kindle, i start stuttering, and the camera of the show goes into the blank space coming out of my face, and then the voice i speak is shown as geometrical shapes.

Events of the day at work.
Problems at home.
People i love who are struggling.
Preparations required for work coming up.
People from my past whom i wonder if they're alive and well.
Etc.

The futures market and the stock market.

"Why can't I sleep?"
