As most women figured out long ago, men are no better than your average mouse or fruit fly:

Male fruit flies that have been rejected by females drink significantly more alcohol than those that have mated freely, scientists say…

The connection between alcohol and this chemical, which in humans is known as neuropeptide Y, has already been noted in studies involving hard-drinking mice.

Yet one scientist insists on raining on my "men or no better than fruit flies" parade:

However, in an accompanying article in Science, Troy Zars of the University of Missouri wrote that "anthropomorphising the results from flies is difficult to suppress, but the relevance to human behaviour is obviously not yet established".

Party pooper.
