Your tax dollars at work: according to this news report (link now dead), the United States government has researched the matter and has scientifically determined that sex makes us happy. Profound grasp of the obvious, there!

What I found interesting, although not surprising, is that the study (of 16,000 people) found that more than a fifth (22%) had not had sex at all in the previous year. You know that intuitive sense you get, that a lot of the people you run into every day badly need to get laid? You were right all along.

My thanks to the friend who sent me the link.
