You say these phrases all the time, but do you know their grim origins?

We toss around old sayings all the time—some without thinking twice. But have you ever wondered where these phrases actually came from? You might be surprised (and a little unsettled) to find out that many of them have pretty grim backstories. Even if we’re keeping things light and curious, you’ll never look at everyday expressions the same way again!

The Mad Hatter may have been lovable and quirky in Alice in Wonderland, but the origin of the phrase isn’t nearly as charming. In the 18th and 19th centuries, hat-makers, especially in England, used mercury in the felt-making process. Long-term exposure to the toxic substance led to tremors, confusion, hallucinations, and even full-blown insanity. So, when someone was "mad as a hatter," it wasn’t a joke, it was actually a tragic side effect of their trade.

These days, "deadline" means you’re rushing to finish your taxes or meet your grandson’s birthday RSVP. But during the Civil War, it was a deadly serious term. Prison camps had an actual line drawn in the dirt—step past it, and guards had permission to shoot without warning.

If your grandkids ever run through your living room like a tornado, you’ve probably said they were "running amok." Originally, this referred to sudden, violent rampages by certain warriors in Southeast Asia. European colonizers didn’t understand it and blamed the devil, but it was likely tied to deep psychological distress. Over time, the phrase softened, but its origins are quite dark, don’t you think?

It might sound like gentle teasing today, but "pulling someone’s leg" used to mean something far more sinister. In the crowded, foggy streets of old London, thieves would trip unsuspecting victims by yanking their legs from behind—either to rob them or help an accomplice mug them more easily. So next time someone says they’re "just pulling your leg," be glad it’s only a joke.

You’ve probably said you were "taken aback" when someone shocked you with unexpected news, right? Did you know this phrase has nautical roots? On a sailing ship, if the wind hit the sails from the front, it could stop the boat dead in the water, or even pull it backwards. That "aback" feeling was equally surprising as it was alarming!

We call fake emotions "crocodile tears," but the story behind it is a bit strange. People once believed crocodiles cried while eating their victims, like they were able to show some kind of twisted remorse. Of course, science has since debunked this theory, but the legend stuck around. So when someone puts on a sad face to get out of chores, just remember: even reptiles have better excuses.

Before painkillers and numbing gels, wounded soldiers had one brutal option during surgery. Can you guess what it was? That’s right, bite the bullet. Literally. On the battlefield, doctors had to work fast and without anesthesia. A bullet between the teeth gave patients something to focus on while wounds were stitched (or worse!)

We know that Shakespeare loved creating new words and phrases, and "the be-all and end-all" is one of his most dramatic. It first appeared in Macbeth when the title character thinks of ending the king’s life as a final, all-important solution. These days, we use it for less murderous things—like the ultimate plane has for some things.

Saying "God bless you" after a sneeze might seem polite, but it stems from a much darker place. In the time of the bubonic plague, a sneeze could be an early symptom, and people feared it meant death was close. Saying "God bless you" was like a quick prayer that you’d survive. Other theories suggest it was meant to keep your soul from escaping. Whatever the origin, it was more panic than politeness.

We say someone’s "wreaking havoc" when they’re causing trouble. But centuries ago, it was an actual military command. Once a battle was won, officers might yell "Havoc!" and soldiers were free to do and destroy whatever they wanted. As you can imagine, the chaos was so brutal that King Richard II officially banned the cry in the 14th century.

What science says

It was false after all: 10 health myths that sound true—but aren't

Health myths are everywhere! These ideas were simply passed down for so long that they became part of what we believed. But now science has stepped in to clear things up. Does cold weather make you sick? Can lemon detox your body? Is reading in low light really harmful? Let's uncover the truth behind 10 common health myths!

Have you ever been told that cutting your hair will make it grow faster? We're sorry to say that's just a myth. Hair grows from the root, not the ends. So, trimming it won't boost growth, though it does help remove split ends that can make your hair look dry or unhealthy.

This is one of the most common health myths. Cold weather often gets blamed, but it's not the temperature that makes you catch a cold. During winter, we tend to stay indoors with others and keep the windows closed, an environment that makes it easier for viruses to spread. That's why colds tend to be more common in winter!

The idea that eating before bed automatically leads to weight gain is a myth. In reality, it has more to do with what you eat and how much, rather than the time of day. Often, when we eat very late at night, we're tired and more likely to reach for quick, high-calorie, heavy foods. This can disrupt sleep and lead to consuming more calories than we burn, both of which may affect weight. If it's close to bedtime, it's better to have something light and healthy in a moderate portion than to skip a meal altogether.

Does wearing glasses weaken your vision? Myth! If an eye doctor prescribes glasses, wearing them as directed helps correct your vision; it won't make it worse. Additionally, the right glasses can help prevent or reduce headaches caused by reading or spending long hours in front of a screen.

This myth is closely related to the previous one. If you love reading and sometimes have to do it in low light because of the situation, don't worry. According to experts, reading in low light doesn't cause permanent or irreversible eye damage. However, it's not recommended because it can make your eyes feel tired or strained, leading to discomfort or headaches.

We're all different, and so are our bodies. The idea that everyone should drink exactly eight glasses of water a day is more of a general guideline than a rule. Staying well hydrated throughout the day is extremely important, but how much water you need depends on factors like your weight, age, climate, and overall health. We should prioritize staying consistently hydrated instead of obsessing over the number of glasses we drink.

Some people say drinking lemon water helps eliminate toxins and cleanse the body. While adding a slice of lemon to your water is a refreshing way to stay hydrated, it doesn't have any special "detoxifying" powers. The vitamin C in citrus fruits is beneficial, but the body has its own natural detox system. The liver and kidneys are the main organs that filter waste and eliminate toxins.

Not all fats are bad! Just like other food groups, your body needs fats to function properly. The important thing is knowing the difference between healthy fats and those that can be harmful. Foods like avocados, seeds, olive oil, fish, and nuts are rich in healthy fats. On the other hand, the fats found in processed or fried foods are the ones that can have a negative impact on your body.

Liver diseases can be serious. While heavy and frequent consumption of alcohol and fats is a major contributor, it's not the only cause. Liver problems can also result from many other factors. These include viral infections, autoimmune diseases, genetic disorders, high blood pressure, and exposure to certain chemicals.

There's some truth to it: breakfast is important because it replenishes our glucose and energy levels and supports proper metabolism. However, the idea that it's the most important meal of the day might be an exaggeration. Everyone's body has different needs, and all meals are important, so we shouldn't skip any of them!
