After the argument, she kept her coworker at arm’s length to avoid more drama.

Remember that friend-of-a-friend you’re not so sure about? The one you’d rather not let get too close? That’s someone you keep "at arm’s length." This common phrase comes from the old practice of measuring distances with body parts (not so old, really; we still measure in feet), and an early version even shows up in Shakespeare’s 1599 play As You Like It, where the line goes: "Hold death awhile at arm’s end."

When my car broke down, a kind stranger stopped to lend me a hand.

Many expressions we use figuratively today started out in very literal situations. That’s the case with "to lend a hand," which originally referred to physically using your hands to help someone with a task. Over time, the meaning expanded, and the phrase can now be used for any kind of help.

His birthday is on the tip of my tongue… wait, is it next Thursday?

You’re chatting with your best friend, remembering old times, when a familiar song pops into your head. You remember the lyrics perfectly, but who was the singer? Ahh… It’s on the "tip of your tongue"! Used in English since the 16th century, this idiom describes those moments when something feels just within reach but doesn’t fully come to mind.

Ever since they met, he’s been head over heels for her.

When was the last time you were completely captivated by someone or something? In those moments, you could say you were "head over heels." The phrase dates back to 14th- and 15th-century English as "heels over head," originally describing literal upside-down movements. Over time, it evolved into its modern form, describing the feeling of being madly in love.

I’d give my eye teeth to get tickets to that concert!

In the past, canines (often called eye teeth because they sit just below the eyes) were among the most important teeth. Losing one was a big deal, which likely explains the origin of this idiom. It’s still used today to describe a major sacrifice or something someone desperately wants.

I bet your ears are burning after that email went around the office.

It turns out your ears can "burn" even when there’s no infection. This kind of burning has a different interpretation: it means someone is talking about you behind your back. It’s not always negative, but it does involve gossip. The idiom comes from ancient beliefs that physical sensations in the body could indicate external events.

Renovating the old house is going to cost us an arm and a leg.

When something costs an arm and a leg, it means it’s extremely expensive or requires a big sacrifice. There are two main theories about its origin: one, now widely regarded as a myth, suggests that in the 15th century, artists charged more if a portrait included the subject’s arms or legs. The other theory links the phrase to the serious physical sacrifices soldiers can make in war.

Break a leg at the competition; everyone’s rooting for you.

When you tell your singer friend to "break a leg," you’re not wishing them anything bad; in fact, it’s the opposite. This idiom comes from old theater superstitions, where saying "good luck" was thought to bring exactly the contrary. To avoid tempting fate, people would say something negative to actually wish someone something positive.

He cried his heart out after saying goodbye to his childhood home.

Since ancient times, people have believed that the heart is where emotions live. So when you "cry your heart out," you’re letting out all your feelings, often very intensely. The phrase usually reflects pain, sadness, ordeep emotional suffering.

Even though we argued, he’s still my flesh and blood, and I’ll always protect him.

This idiom is much less creepy than it might sound at first. To be someone’s "flesh and blood" means you are part of their family, or are treated as if you were. Some sources trace one of the earliest uses of this phrase to an Old English translation of the Bible, specifically in Matthew 16:17.

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!
