The Difference Between Hoarding And Collecting

Between 700,000 and 1.4 million people in the United States alone have issues with hoarding, and the difference between hoarding and collecting is largely how a person feels about their surroundings. Collectors are proud of their items and display them, while hoarders keep their possessions because they can’t bear to throw them away, even though they’re ashamed. They feel anxious whenever anyone asks them about getting rid of things and, unlike collectors, there’s often an element of disorganization to their stash.

The Difference Between A Real Smile And A Fake One

Admittedly, some people are better at pulling it off than others, but according to scientific research, there’s still a definite difference between a real smile and a fake one. It all has to do with the interaction of the muscles around the mouth and cheeks with the muscles in the eyes, and there’s only one unique combination of these muscle movements that results in a smile that means happiness or contentment. Other types of smiles—including the one that you give at a really bad joke—can mean anything from sadness and smugness to barely concealed annoyance.

The Difference Between Pigs, Hogs, And Wild Boars

Pigs, hogs, boars—they all wallow in mud, root around, and can destroy nearly any vegetation in their path. But what makes a pig a pig and not a boar or hog? Ultimately, there’s no cut-and-dried difference, because farmers, hunters, and regular folk all use these terms a little differently and interchangeably. However, “pig” usually refers to the barnyard variety, a wild boar is the kind that lives out in nature and is the ancestor of domestic pigs, and “hog” is used to describe larger pigs and boars.

The Difference Between Teenage Brains And Adult Brains

Teenagers can look like adults, dress like adults, and even act like adults at times; sometimes, it might be hard to tell the teenagers from adults (and other times it isn’t hard at all). But it’s also crucial to remember that their brains are wired completely differently. It’s long been known that at the end of the day, teenagers just don’t think like adults, and that’s because the different sections of their brains aren’t connected the way they will be once they’ve matured a little more. Most specifically, teenagers lack many of the nerve connections that tie the frontal lobe to the rest of the brain, limiting their ability to think ahead.

All The Different Kinds Of Lightning

Throughout the centuries, lightning has been mistaken for many things, from UFOs to the spirits of the dead. There are so many different kinds of lightning that it’s not surprising that sometimes people just don’t recognize it for what it is. In addition to the most common lightning that accompanies thunderstorms, there’s also the ball lightning that many see as a UFO, the jellyfish-like red sprites, blue jets that are more often seen from the sky than from the ground, and the rather disturbing dark lightning, that you may have been hit by without knowing it.

The Different Ways To Be Dead

The more we learn about the human body, the trickier it is to define just what death is. A person can be different types of dead; when a person is declared brain dead, that means that all brain activity has stopped, including control over the rest of the body’s function. But there’s also circulatory death, in which only the lungs, heart, and the circulatory system stop functioning. One can happen without the other, and it’s led to some tricky moral questions about just when a person is legally, absolutely, completely dead.

The Benefits Of The Different Types Of Naps

There’s a lot to be said for the benefits of napping, and taking differently timed naps during the day can provide you with quite the variety. Short naps lasting no more than about 20 minutes will increase your immediate processing ability, while slightly longer, 60-minute naps can provide you with a boost to your creativity. And 45-minute naps will leave you with health benefits like lowered blood pressure.

Telling The Difference Between Real Memories And False Ones

Separating false memories from real ones is a tricky thing; sometimes our brain creates false memories to protect itself, or, occasionally, on accident when it puts together information in such a way that it suddenly revolves around us instead of the friend we heard the story from. But science can tell the difference. The body has a series of involuntary movements that can reveal whether we’re remembering something that really happened or not, and our brain waves actually follow different patterns when they’re retrieving something we’ve actually seen, heard, or experienced and filed away for future use.

The Many Different Types Of Ice

Ice seems like one of the most straightforward concepts out there—it’s just frozen water. But there are many, many different types of ice, forming under different conditions and even in different temperatures. For example, glaze ice forms when water that’s above freezing hits a cold surface that supercools it and forms a clear coating. Hail is ice that starts as frozen rain, growing as it rises and falls through the atmosphere. And pack ice is frozen seawater that freezes at varying temperatures because of the salt content.

The Many And Varied Types Of Archaeology

Archaeology is one of those careers we’d all like to have, as long as we can be Indiana Jones. It’s rarely like that, though, and it’s also one of those careers that’s been vastly misrepresented by the media. Archaeologists aren’t just archaeologists: They’re marine and underwater archaeologists, prehistoric archaeologists, battlefield archaeologists, aerial archaeologists, or even biblical archaeologists.
