Wow! It seems like the scientists are working overtime on the less than reliable sounding hormone studies!
Today, MSNBC reports that women with high levels of estrogen look and feel prettier, but are less inclined to have long term monogamous relationships.
Or, you know, you could look at it this way- people who feel more attractive and more confident also feel as though they don't have to settle. But that would make too much sense, so they had to throw estrogen in there to make it more sciencey.
