I found the second article (hidden beneath the credits and the book ads) about monkeys adopting currency much more interesting. I know people who do primate research and it doesn't surprise me in the least, but it's much more interesting than the first, which can be summarized as "high-end prostitutes have a good life and make a lot of money, low-end prostitutes have a shitty life and make no money" with the rest being a mix of stereotypes and overconvoluted explanations of the demand curve.
