What's your top pet peeve? Open-mouthed chewing? Nail biting and knuckle cracking? The sound of silverware scraping? Or perhaps it's a bigger behavior, like leaving the toilet seat up?
From day to day, it can be difficult to remember everything that's required of you. I tend to forget exactly where it is I'm supposed to be during my busiest moments, and it's even easier to delete each day's events out of your brain when there's so much else that dominates your mind. Yet taking the time to remember exactly what it is that happens during each of our days can be a vital part of our memory—and with nothing more than 15 minutes, we can strengthen our brains and remember more tha...
Whether you're a serious, sweating athlete or just need to recover after a night of drinking, chances are you've replenished your body's fluids with a sports drink at some point. Those electrolytes aren't the only thing entering your systems, though. Sports drinks are sugary, sweet, and loaded with calories—but there's a way you can still recharge your body without ingesting the unhealthy additives.
Are you a follower or a leader? No matter how you respond, we all know that leader is a more desirable position to hold. Great leaders typically share a few qualities—confidence, intelligence, and strength, to name a few—but one of the most intriguing is their appearance. With the right facial structure, and some well-rehearsed expressions, you can trick others into thinking you're leader material.
We tend to assume that eating is mostly a physical act, but the mind has so much to do with the choices we make.
Journals are a great source of hilarity and embarrassment, detailing everything from your elementary school crushes to those super awkward middle school dances. While rereading your old hand-scrawled entries might make you cringe, that old journaling habit could benefit you as an adult.
Think eating food is as easy as putting it in your mouth? It's considerably more complicated than that. Your brain plays a big role in determining what and how you eat. Understanding how your brain interprets food choices is key to managing your eating habits.
Tequila is a hard liquor that's often been misunderstood. Produced from the agave plant, this aged spirit has complex flavors that bloom the longer it's aged and can rival the finest scotch.
An open bottle of wine can be dangerous. You intend to enjoy—nay, savor—a single glass, but then two episodes of Top Chef later, that sucker is empty. Now you have to go to work the next day with a wine hangover. What happened? Turns out there are some unconscious reasons you might be chugging more wine than you wanted. Never fear. Along with clenching your fists to make better food choices, there are some tricks you can use to moderate your wine intake. Researchers at Cornell University disc...
I have an embarrassing habit: I type with six fingers. Just as your grandma pecks at the keyboard with her two index fingers, I rely solely on my index, middle, and thumb fingers only. But it's not as slow as you think, and I'm not the only one out there that does it.
Cats. Whether you love 'em or hate 'em, you've got to admit—they've got minds of their own. While this makes them incredibly entertaining at times, it can also cause tons of issues for their owners. Trying to "train" a cat is usually an exercise in futility.
Dianne Tice and Roy Baumeister gave a bunch of college students a questionnaire in which the students answered questions about their work habits.

Ahoy, landlubber! Next to vampires and werewolves, seafaring pirates are going to be the most popular costumes this Halloween. And luckily, you don't need to pillage or plunder in order to prove your scoundrel worthiness.
It's funny to us that so many Victorian makeup looks done for Halloween emphasize heavy, dead makeup with lots of deep plums and reds because the Victorians wore little to no makeup (women were basically considered whores if they wore rouge).
Hydrogen can be used to improve mileage. The hope with this method is that hydrogen will increase the amount of gasoline combusted and increase fuel efficiency, as you trickle hydrogen into the tank. Often propane is used to increase gas mileage. The studies are still being done. There's no official data at present, but there is significant experimentation.
