Models vs. Supermodels: What's the Difference?

The Quick Trick: A model gets arrested for snorting cocaine; a supermodel gets on the cover of People for snorting cocaine.

The Explanation:

Like beauty itself, supermodeldom is in the eye of the beholder. One day, perhaps, there will be a Model Sanctioning Body that will establish clear rules for who qualifies as a supermodel—but until then we'll just have to muddle our way through. The difference between regular and super models is generally believed to involve not money but fame: A supermodel is someone whose celebrity extends outside of the fashion world. That is to say, you don't have to know your Dolce from your Gabbana to know that Cindy Crawford is really pretty.

Janice Dickinson, the thrice-divorced Surreal Life alum who wrote the literary gem Everything About Me Is Fake . . . And I'm Perfect, coined the term supermodel in 1979. Hence, she calls herself the world's first supermodel. But we feel that no one who ever appeared on Surreal Lifeshould be legally allowed the title of "super" anything. A better candidate for first-ever supermodel might be Suzy Parker. Born in 1932, the 5'10" Parker ushered in the era of tall female models, starred in many ad campaigns, and appeared in the movie Funny Face with Fred Astaire. She also became one of the first fashion models to be really, really bad at acting. But being unable to act your way out of a paper bag is just all part of la vita supermodel.

Nadja Auermann: Said to have the world's longest legs (they're 45"), Auermann has appeared on many magazine covers, starred in a couple German movies, and has her own perfume. But 1) these days, everybody has her own perfume, and 2) nobody outside of Germany can pronounce her last name. Verdict: model.

Naomi Campbell: Instantly recognizable, Campbell's made $50 million modeling, was one of People's 50 Most Beautiful People in 1991, wrote (well, cowrote) a novel, and sold one million copies of her first and only album, Babywoman. (It was a failure in America, but a single from it was a huge hit in Japan.) Plus, she used to date Usher. Verdict: supermodel.

Helena Christensen: This former Miss Denmark changed our lives forever with her appearance in the music video for Chris Isaak's Wicked Game. And she dated Leonardo DiCaprio (although, really, at this point who hasn't?) in addition to appearing on the cover of countless fashion mags. But she never managed to parlay the Wicked Game video into widespread renown. Nothing personal, Helena, but we're gonna say: model.

Tyson Beckford: A former gangbanger who left the streets behind to become the face of Calvin Klein apparel, Beckford is the highest-paid male model in human history. He also appeared in Zoolander and 2003's Oscar-nominated Biker Boyz. What's that you say? Biker Boyz wasn't nominated for an Oscar? Oh, well. The verdict's still: supermodel.

What's the Difference Between Cement and Concrete?

Picture yourself walking down a city block. The sidewalk you follow may be obscured by shuffling feet and discarded gum, but it’s clearly made from something hard, smooth, and gray. What may be less clear is the proper name for that material: Is it concrete or cement? Is there even a real difference between the two words?

Though they’re often used interchangeably, concrete and cement describe different yet related elements of the blocks, flooring, and walls that make up many everyday structures. In simple terms, concrete is the name of the gray, gritty building material used in construction, and cement is an ingredient used in concrete.

Cement is a dry powder mixture that looks much different from the wet stuff poured out of so-called cement trucks. It’s made from minerals that have been crushed up and mixed together. Exactly what kind of minerals it’s made from varies: Limestone and clay are commonly used today, but anything from seashells to volcanic ash is suitable. After the ingredients are mixed together the first time, they’re fired in a kiln at 2642°F to form strong new compounds, then cooled, crushed, and combined again.

This mixture is useless on its own. Before it’s ready to be used in construction projects, the cement must be mixed with water and an aggregate, such as sand, to form a moldable paste. This substance is known as concrete. It fills whatever mold it’s poured into and quickly hardens into a solid, rock-like form, which is partly why it’s become the most widely-used building material on Earth.

So whether you’re etching your initials into a wet sidewalk slab, power-hosing your back patio, or admiring some Brutalist architecture, you’re dealing with concrete. But if you ever happen to be handling a chalky gray powder that hasn’t been mixed with water, cement is the correct label to use.

Why Do You Stop Feeling Tired As Soon As You Climb Into Bed?

There are few situations more frustrating: After a day spent nodding off at your desk, on the train, and on your couch, you suddenly can't sleep the moment you crawl into bed. It's not that you aren't tired or have insomnia, necessarily. Like a curse designed just to torture you, the sleeplessness only seems to occur when you're in your own bed at home, a.k.a. the place where you'd prefer to do your sleeping.

This maddening problem isn't in your head. According to TIME, many people have more trouble falling asleep in their own beds than they do elsewhere thanks to a phenomenon called learned or conditioned arousal. Conditioned arousal develops when you inadvertently train your body to associate your bed with being awake. In many cases, this results from doing stimulating activities in bed. For instance: If you like to slip under the covers and spend 40 minutes watching Netflix before closing your eyes, you're teaching your brain that your bed isn't for sleeping. That means the next time your head hits the pillow, your body will respond by preparing for the next episode of Friends instead of releasing the chemicals that help you fall asleep. The same goes for scrolling through apps, eating, and even reading in bed.

Doing things that aren't sleeping in bed isn't the only way to develop conditioned arousal. If there are other factors keeping you up at night—like thoughts about your day, or that cup of coffee you had at 8 p.m.—they can lead to the same result. Your brain starts to associate being in bed with tossing and turning all night, so even if those mental and physical stimulants go away, the muscle memory of being awake in bed remains.

Conditioned arousal is a vicious cycle that can't be broken in one night. The only way to manage it, according to the American Psychological Association (APA), is to minimize behaviors that contribute to poor sleep habits and to reserve your bed for sleeping (though sex is OK, according to the APA).

If you're a nighttime scroller, browse apps in a different room before getting into bed, or skip checking your phone at the end of the day altogether. When you spend more than 20 minutes struggling to fall asleep in bed, get up and move to a different part of the house until you get sleepy again; this will stop your brain from strengthening the association between your bed and feeling restless. The results won't be instant, but by sticking to a new sleep routine, you should eventually train your body to follow healthier patterns.

Of course, combating conditioned arousal alone isn't always effective. In people with conditions like anxiety and insomnia, intrusive thoughts and genetic factors can prevent them from falling asleep even under ideal circumstances. In such cases, the help of a medical professional may be required to sleep more soundly.
