Happiness is ...

We talk a lot about happiness. On the white album, the Beatles had a song entitled; "Happiness is a Warm Gun." Most people don't talk about what "happiness is", instead, they talk about what makes them happy. Last night, after I ate, I was out on Digg.com and I came across this link. It won't tell you what happiness is, but if you go down to the bottom of the page and click on "functions". Then in the left column, click on "happiness", it will show you where in the brain "happiness" occurs.
