"Scientists in England gave 84 heterosexual college students chilled lime-flavored drinks that were either non-alcoholic or given a dose of vodka equivalent in alcohol to a large glass of wine or a pint-and-a-half of beer.
After 15 minutes, the volunteers were shown photos of 40 other college students from both sexes. Both men and women who drank booze found these faces more attractive, "a roughly 10 percent increase in ratings of attractiveness," said researcher Marcus Munafo, an experimental psychologist at the University of Bristol in England."
