Good luck, bad luck

Have you ever broken a mirror? Let's demystify these 10 superstitions

Do you have rules you follow "just in case"? Some of us avoid walking under ladders, hesitate before opening umbrellas indoors, or instinctively knock on wood after saying something… But

where did these rituals come from? Why did some everyday accidents, animals, or gestures get labeled "unlucky"? Let’s explore some of the answers and whether they have to do with psychology, religion, history, or plain old common sense!

1

Walking under a ladder

For one, there’s the safety concern: Why would you walk under a ladder if you could avoid the –albeit low– risk of it falling on you?

However, this superstition is also linked to the medieval Christian belief that interrupting a shape resembling a triangle was a way of insulting the Holy Trinity. Again: Why risk it?

Breaking a mirror

Have you ever shattered a mirror and winced at the thought of years of bad luck? This goes back to ancient Greece and Rome. There, reflections were thought to be linked to the soul. Destroying a mirror was considered an affront to the gods watching over your spiritual self.

The "seven years" bit comes from the Roman idea that the human body renewed itself in seven-year cycles.

Celebrating a birthday early

"You’ll jinx it!" is a common reaction when someone celebrates before their actual birthday. This superstition appears across several European traditions, where marking a milestone before it arrives was seen as presumptuous, even disrespectful to fate.

In eras when illness and mortality were real daily concerns, reaching your birthday wasn’t guaranteed… so celebrating early felt like counting blessings before earning them.

A black cat crossing your path

In ancient Egypt, black cats were revered and associated with protection and prosperity. What happened to their reputation, then? Simply put, in medieval Europe, when fear of witchcraft ran rampant, cats (especially the poor black ones) became linked with witches.

However, beliefs vary widely: in Britain, Ireland, and Japan, black cats can signify good luck or fortune, and sailors once welcomed them aboard ships to ensure safe voyages.

Friday the 13th

In many Western traditions, both Fridays and the number 13 had separate unlucky connotations long before they were combined: Friday was sometimes seen as ill-fated in Christian lore (Jesus’ crucifixion is said to have been on a Friday), and 13 was viewed with suspicion in Norse myth (where Loki’s unexpected arrival as the 13th guest at a feast led to chaos).

Opening an umbrella indoors

When early umbrellas with stiff metal frames first became popular in Britain and Europe, they were hard to fold and easy to jab into furniture, lamps, or unsuspecting family members. That made opening one inside genuinely hazardous, and turning it into a superstition was a tidy way to say, "Please don’t do it."

7

Knocking on wood

Almost everyone does this reflexively: you say something hopeful and then tap wood to "keep the luck going." One theory ties this to pagan traditions in Europe, where people believed protective spirits lived in trees; knocking on the trunk was a way to call on those spirits or to secure their goodwill.

Spilling salt

Salt was once very precious: it preserved food, flavored meals, and even served as currency in parts of the ancient world. Spilling it meant waste, and waste invited misfortune. But, of course, everyone knows the fix: throw some over your left shoulder.

Stepping on a crack

"Step on a crack, break your mother’s back." This ominous-sounding rhyme isn’t ancient at all; it rose to popularity in the early 20th century, spread through schoolyards rather than folklore. Of course, there is no logical explanation to back it up. But if you are superstitious… why would you risk it?

10

Seeing a solitary magpie

"One for sorrow, two for joy"... In British and Irish folklore, seeing a single magpie was thought to signal misfortune, loneliness, or bad news. The belief probably just pointed at how unlikely it is to see only one of these beautiful birds. To counter the bad luck, people developed rituals: tipping a hat, greeting the bird politely, or even saluting it.

Being a "treasured guest" is not a compliment. This is the hidden meaning

Have you ever heard "Code Adam" while shopping for groceries at Walmart? Or maybe you’ve heard how "Dr. Firestone" was being paged during a routine hospital visit. They sound like harmless announcements. But behind these ordinary words are secret codes staff use to signal emergencies without causing panic. From hospitals and supermarkets to airports and Disney Parks, these phrases quietly warn employees that something is happening. You hope you never hear them, but if you do, it helps to know exactly what they mean.

Treasured guest

We all love getting special attention at airports or hotel desks, but if you hear the clerk call you a "treasured guest," don’t feel so flattered. You may not be as VIP as one could think.

In the hospitality industry, "treasured guest" has become a humorous bit of industry folklore to describe someone causing trouble. Maybe a customer yelling at staff over expired coupons, demanding impossible accommodations, or throwing a full-blown tantrum at the front desk. Whatever it is, the phrase has become the staff’s secret way to warn co-workers without escalating the situation in front of the customers. Most guests don’t realize the meaning, but once you know it, you may start hearing it more often. We just hope it’s not about you.

Code Adam

Imagine you’re pushing a shopping cart through Walmart when suddenly the overhead speaker announces, "Code Adam." You can easily assume it’s some kind of employee meeting or cleanup request. But when you see them start locking the exits and moving around, you know something’s wrong.

This code was created in 1994 by Walmart in collaboration with the National Center for Missing & Exploited Children (NCMEC), in memory of the tragic case of 6-year-old Adam Walsh. Adam was abducted from a Sears department store in 1981 while shopping with his mother. His father, John Walsh, later became famous for hosting the TV program America’s Most Wanted and advocating for missing children. Even if Adam’s story ended in tragedy, Walmart created the emergency system in Adam’s memory, and other retailers soon adopted it nationwide, intending to have a quick response to missing or abducted children.

Code Blue

You’re sitting in a hospital waiting room during a routine check-up when you suddenly hear "Code Blue, Room 214." Most people immediately know it sounds serious, even if they are not entirely sure why.

The phrase "Code Blue" is used at hospitals to draw the necessary staff and equipment to perform a resuscitation. It was created in the early 1960s at Beathany Medical Center by Dr. Hughes Day. Before then, hospital resuscitations were often chaotic and poorly coordinated. In 1961, Dr. Day received a grant to build one of America’s first cardiac care centers, and he developed both the Code Blue alert system and the modern crash cart to improve survival rates during cardiac emergencies. Today, the system is used in hospitals across the country, sometimes with specialized versions like "Code Blue Pediatric" or "Code Blue Neonate."

Dr. Firestone

Imagine visiting a loved one in the hospital when the intercom calmly announces, "Paging Dr. Firectone to the third floor." Your head surely goes, "Dr. Firestone’s probably having a busy day up there." He is, but it’s not what you think.

The phrase is actually a discreet fire alert used to warn staff about smoke, flames, or overheating equipment without frightening patients and visitors. Hospitals adopted these coded announcements after realizing that openly yelling "fire" over loudspeakers could create panic, especially among patients who aren’t able to move quickly. "Code Red" is an alternative used by many health centers today, but it also hints at the situation while keeping hallways calm.

Code 10

You’re standing at a checkout counter when the cashier picks up the phone and quietly says, "I need a Code 10 authorization." If you think that’s just another way to get a supervisor’s approval or technical issue, think again. In reality, the cashier may suspect the credit card is stolen or fraudulent.

Code 10 was developed through a cooperative effort between major credit card companies like Visa and Mastercard, along with international standard organizations. As credit cards became more common in the 1960s and 1970s, stores needed a discreet way to alert banks about suspicious activity without directly accusing customers and potentially putting employees at danger. When a cashier requests a Code 10, the bank’s operator begins asking yes-or-no questions to assess the situation and guide the employee on what to do next.

Code Bravo

You’ve probably experienced those long airport security lines. The wait is usually uneventful. But sometimes, you can hear "Code Bravo" over the speakers. Maybe it’s a delay, or maybe it’s an issue with luggage. Within seconds, people stop moving, the security line freezes, and exits may even close. It’s something bigger.

Code Bravo is the emergency phrase used by airport security and the Transportation Security Administration to signal a serious security threat, such as an unattended bag, a breach at a checkpoint, or someone slipping into a restricted area. The term comes from the international phonetic alphabet used in aviation and military communications, where "Bravo" represents the letter B. When this is called, security staff immediately lock down affected areas, stop screening lines, and search for the source of the threat. To passengers, it’s sudden and confusing, but to security, it’s a carefully rehearsed response.

Code Alpha

You are heading back to your cabin on a cruise ship when the speakers announce, "Code Alpha, Deck 7." You may think Alpha is related to the captain, but that’s not the case. It means someone on board is suffering a medical emergency.

The phrase comes from the NATO phonetic alphabet, where "Alpha" represents the letter A. In maritime emergency jargon, it became shorthand for a Priority A medical situation requiring immediate response. Cruise lines such as Royal Caribbean and Disney Cruise Line commonly use the term, though some ships use variations like repeating "Alpha" three times. Once the code is announced, onboard medical teams rush toward the specified deck or cabin. If necessary, stretcher crews are mobilized, and in severe cases, the ship may even divert course toward the nearest port for emergency evacuation. Passengers are enjoying the views, but the staff is running to save a life.

10-33

Anyone who remembers the CB radio craze of the 1970s probably smiles when they hear "10-4." Movies, truckers, and radio fans turned those number codes into a part of American culture. So if you overhear "10-33" on a police scanner, you might assume it’s just another routine message. But it’s not as simple as it sounds.

The 10-code system was first created in 1937 by Illinois State Police communications director Charles Hopper and later standardized by the Association of Public Safety Communications Officials, better known as APCO. Officers needed short phrases they could understand clearly over crackling radio signals. The 10-33 code commonly means an officer needs emergency assistance. In some departments, it also signals radio silence so dispatchers can focus on the crisis unfolding in real time.

Signal 70

Disney World is amazing, the parks offer something for everyone, and there are things to see wherever you look. But that’s exactly the kind of place where a child can easily disappear into a sea of strollers, balloons, characters, and crowds. For that reason, Disney has developed the "Signal 70," which alerts cast members and security that a child has become separated from their family.

The number comes from older police and emergency radio systems, where "70" was commonly associated with missing persons. Disney adopted the phrase because it allows employees to communicate discreetly without frightening or alarming nearby guests. If a member finds the child, they gently -and magically- escort them to Baby Care Center, where they coordinate the reunion.

Echo, Echo, Echo

Cruises are great to relax, enjoying a good book under the sun with a nice drink by the side. Until you hear "Echo, echo, echo" on the speakers. If you do, something is happening somewhere else on the ship.

The code is used among cruise employees to signal that dangerous winds or a navigational hazard are affecting the ship. It comes from the international maritime phonetic alphabet, where "Echo" stands for the letter E. In maritime signalling, the letter traditionally means "I am altering my course to starboard." And, in time, the phrase became associated with urgent ship maneuvers and weather-related warnings. However urgent, the repetition of the word by three doesn’t represent life-threatening situations. It alerts the crew of a certain hazard to prepare while avoiding panic among passengers.
