A customer sips a cappuccino at a Starbucks coffee shop in Seattle.
A new study out of the U.K. today suggests that drinking coffee makes women smarter and men dumber.
According to Bristol University, coffee increases women's brainpower in stressful situations, while at the same time it makes men slower.
Test subjects were given a multitude of tests to perform, as well as a cup of coffee.
While performing the tasks, researchers found that men who drank the coffee performed much slower in memory tests, as well as completing puzzles.
For the women, the coffee actually enhanced their performance.
