There’s too much Internet—it taught us the right way to use a seesaw this week—and too little time. That's why we curate a list of the best of the best (aka "the Greatist") things we've come across on the Web this week. In other words, it's the stuff we'd email/gchat/tweet/text you immediately if we were besties. While we'll never stop striving to bring our readers amazing content on a daily basis, we know not all the best stuff comes from us.

1. Why Does Beer Smell So Delicious? (Modern Farmer)

If the aroma of beer didn’t smell so good, maybe we wouldn’t drink so much. But Belgian scientists discovered that beer doesn’t use its fruity scent to attract us. The hoppy beverage actually puts out its beautiful scent for fruit flies. And those fruit flies do double duty: breaking down sugars (the byproduct of fermented yeast) and then spreading those yeasty organisms wherever they fly.

2. These Researchers Found a Way To Make Calorie Labels That Actually Work (Vox)

We’re all trying to make healthier decisions, but science shows our brains are basically kids in a candy store wanting to eat as many calories (read: pizzas, cookies, cakes) as possible. Can looking at a nutritional label really be enough to stop the hunger monster (er, our brain)? Turns out knowing the soda in our hands is going to take 50 minutes of exercise to burn off is a more effective way to get humans to eat healthier than a nutritional label that says that same can of soda is 250 calories.

3. Why Introverts Should Avoid Coffee (Science of Us)

Sure, a cup of joe might seem like a great idea before a big presentation or meeting—it can be just the the thing you need to perk up and be more alert. But if you’re the shy type, you may want to steer clear of caffeine. Introverts’ brains function at a naturally higher state of alertness, so a cup of coffee can push them to be overstimulated.

4. What the World Eats (National Geographic)

Americans have a reputation for eating more than their fair share of meat. (The Atkins and paleo diets aren’t doing much to help the cause.) So, how do we stack up against other countries? Lucky for us, our friends over at National Geographic pulled five decades of data from the Food and Agriculture Organization of the United Nations and put together beautiful pie charts of daily diets from around the world. China and Hong Kong consume more meat than us, but we take the cake (literally) when it comes to sugar and fat intake.

5. How Music Can Boost a High-Intensity Workout (The New York Times)

As any SoulCycler will confirm, the perfect playlist can get you through even the most grueling workouts. And now we’ve got science to back up that claim—even for high-intensity interval training. A recent study looked at the effects of listening to music on a cycling class that included 30-second all-out bursts followed by a period of more leisurely pedaling. Participants found the class to be hard with or without the music, but they managed to exert more energy—and burn more calories—when the music was bumpin’.

6. The Best Personality Trait for Your Health (Refinery29)

Your mother was right when she said, “It’s what’s on the inside that counts.” At least when it comes to your overall health. But which personality trait is the most beneficial? Conscientiousness tops the list, so long as it’s not met with a touch of neuroticism. It’s great to follow a doctor’s orders, but not so great to endlessly ruminate about what might be wrong.
