"Freakonomics" and "Super Freakonomics" are humorous and chatty books about people:
- what makes us give to charity
- why an IT specialist chooses to "turn tricks"
- school teachers
- drug dealers who live with their moms
- ... all that plus three easy way on how to avert the global warming crisis.
Read one or both of them. That's coming from me, someone who dislikes non-fiction almost as much as she loves fiction.
