Coffee makes you dumb

And I used to wear those heart palpitations like badges of honor.

Drinking a moderate amount of caffeine might step up your smarts, but that benefit decreases the more you drink, according to a new study.

Researchers found that students given the lowest dose of caffeine used in the study — equivalent to half a can of Red Bull – had the best responses to a reaction-time test, which required them to respond to targets on a computer screen. But those that drank more caffeine had slower reaction times.
