We’ve always been warned about the dangers of coffee.

After all, caffeine is a drug (a stimulant!), and as a rule we tend to categorizes all drugs as “bad”.

But recently there’s been a study that can dispel those myths. John’s Hopkins came to the conclusion that caffeine can help with memory consolidation.

Best dose? 200 mg, as The Atlantic notes, about half of a Starbucks Venti coffee. But Mr. Mike Yassa, who may or may not have a burgeoning  caffeine addiction, is not the only one who has noticed the positive effects of coffee consumption.

Several other studies (here and here) noted that, unlike urban legend, moderately consuming coffee does not necessarily contribute to dehydration. Oh, and by the way? Daily consumption of coffee or green tea decreases your risk of stroke. Even historians praise humanity’s ongoing caffeine addiction: It allowed us to “sober up” and create “a more productive society”

You hear that? Yeah, that’s the sound of college students everywhere rejoicing.

But don’t overdo it ’cause you know what else is important? Sleep.
