Women get high by talking?

I read this Daily Mail article about how women talk about 3 times more that men. Through my experince (mainly through my dear wife and oldest daughter), the article sounds accurate, thought I believe the ratio should be closer to 4 or 5 times more ;) That being said, the following sentence jumped out at me:

And, if that wasn't enough, the simple act of talking triggers a flood of brain chemicals which give women a rush similar to that felt by heroin addicts when they get a high.

I had always thought that some people like to hear themselves talk, but I never thought that they were getting high doing it!
