Here is some info about the PBS documentary we watched on Monday. You won't be directly asked about the content of the video for the exam, although it helps put many of the topics we've discussed in context, so it might help. And it's interesting.
Many clips of the documentary can be found on Youtube, and it's available on Netflix instant streaming for those of you who have access to it.
The host, Dan Gilbert, is a social psychologist at Harvard whose research has been mentioned a number of times in the course. You can find his TED talk on happiness here.
