Fun facts you’ll want to share

They know what you want: What you ignore about the most popular apps

We carry these apps with us in our pockets everywhere we go. Yet how little we know about them… Did you know TikTok can learn how to make you laugh in less than an hour? Or that Google’s first server was literally built with toys? Or the percentage of songs on Spotify that have never been heard by anyone –ever? Here’s a list of fun facts that you’ll want to share with your friends.

This story sounds made up, but you can Google it yourself. In its very early days, Google’s founders stored the company’s first server in a box made of… Lego bricks! It held ten 4 GB hard drives.

As you can imagine, that colorful, practical, creative image cemented the same aesthetic that Google is nowadays so well-known for.

Gone are the days when we judged people harshly for posting pictures of the food they ate.

The strange habit of showing the world your meal via Instagram is a die-hard, worldwide trend. And the most Instagrammed food globally is #Pizza (with 75.6 million posts), followed by #Sushi (39.2 million).

Has this ever happened to you? You log into Netflix and find a romantic poster for a brand new series. But when your friend goes in through his account, the same series has a poster that makes it look like a horror show.

This is intentional: Netflix famously runs tests on almost everything, including the artwork you see for a show. They know what you’d prefer to watch!

Yes, many people use Twitter (a.k.a. "X"). But only about 10% of those active users are responsible for around 92% of all tweets.

In other words, most people lurk and use the site to get their instant news or a few laughs. Very few accounts produce the content!

The first logo of Facebook (around 20 years ago, when it was still "thefacebook.com") used a portrait; specifically, it was a white-and-blue profile of the young face of actor Al Pacino. You can still look up that old logo.

Massive and popular as Spotify is, a big part of it is completely unexplored. That’s because roughly 25% of the songs on Spotify have never been played.

Are you thinking about the poor artists whose songs have 0 plays? Well, consider this: A 2024 report showed that around 99,000 new tracks were uploaded every day!

If you type Relentless.com into a browser today, it still redirects to Amazon. That’s because "Relentless" was one of the early names considered.

"Cadabra" (as in abracadabra) was another early option, but it was changed because the founder’s lawyer noted it sounded too much like "cadaver."

It would be impossible for a human to watch even a third of YouTube’s content in a lifetime. The site has 5.1 billion videos, and the number keeps growing: More than 360 hours of new content are uploaded every minute.

WhatsApp is one of the world’s leading messaging apps, and it is currently owned by Facebook. But it was created by two former Yahoo employees who were repeatedly rejected from jobs at Facebook… and then Facebook ended up buying their app for 19 billion dollars.

TikTok’s algorithm is so precise that studies show it can figure out your preferences in about 40 minutes of use, just from what you linger on. That is scary-precise technology.

Also, TikTok has been the most downloaded app in the world since 2020, surpassing even Facebook and Instagram.

Wikipedia supports one of the largest knowledge bases on Earth. Yet it runs on a budget far smaller than people assume, roughly comparable to a mid-size NGO.

It’s edited by a surprisingly tiny active community. A small percentage of editors maintain a huge portion of the platform.

Would you trust information found in "r/AskReddit"? As it turns out, it is officially one of the site’s most influential subreddits and has shaped countless journalism pieces, TikToks, and YouTube videos. So, basically, it has transformed organically into a quiet content engine behind the internet.

Hospital secrets

What is a "Code Gray" and what you should know if you hear it at the E.R.

A trip to the emergency room can be stressful enough without hearing doctors and nurses speak a language that sounds like a secret code. One minute, someone is asking for medication "STAT," the next there’s a "Code Gray," and another patient is suddenly "NPO." What do those words really mean? Some are official medical terms, others are insider slang, but they all help hospital staff communicate quickly when every second counts. Here are 10 of those codes explained.

The E.R. can be hectic and unpredictable. Most patients are frightened or uncomfortable, but now and then someone becomes aggressive because of pain, confusion, mental illness, or the effects of alcohol or other substances. That’s when you can hear "Code Gray" announced over the speakers.

The code is used to summon security officers to help manage a violent or combative situation. While color codes vary from one hospital to another, Code Gray commonly signals that staff needs extra assistance to protect patients, visitors, and healthcare workers. Even if you know it now, most people in the waiting room never know what happened, and that’s exactly the point.

You have a scheduled surgery, you’re in your bed waiting to be taken to the surgery room, and you ask for a cup of coffee to make the wait lighter. The nurse will probably tell you you’re an NPO. You may think it’s serious, but it’s simply a procedure.

"NPO" is an abbreviation that comes from the Latin phrase Nil Per Os, which means "nothing by mouth." It tells patients they cannot eat, drink, or sometimes even take medication until doctors say it’s safe. The rule is most common before surgery or certain medical tests, when food or liquids could increase the risk of complications or alter the results. It may be frustrating, but it’s an important part of keeping patients safe.

You’ve probably been through the experience of visiting an emergency room, either to get checked or to visit a loved one. In that part of the hospital where everyone is rushing to save lives, you’ve probably heard a doctor asking for the R.C.P. cart or medication "STAT!" It sounds urgent, and that's because it is.

The expression comes from the Latin statim, which means "immediately" or "without delay." Hospitals have used Latin medical terms for centuries, but STAT is one of the few that remains part of everyday conversation. When a doctor says it, the request jumps to the top of the priority list. It doesn’t always refer to a life-or-death situation, but it does mean the medical team needs something done as quickly as possible.

Newborns are always a reason to celebrate at the hospital. Parents usually rest happily next to their child as they receive congratulations from close relatives. However, the hospital is always prepared to handle extremely rare emergencies under "code pink."

If you hear a "Code Pink," it usually means a baby or young child is suspected of being abducted from the hospital. Within seconds, security officers respond, exits may be monitored or blocked, and staff begins following carefully rehearsed procedures. Although different hospitals sometimes use different color codes, Code Pink has become widely recognized across North America as one of the most serious alerts a hospital can issue.

If you’ve ever spent a few days in the hospital, you’ve probably noticed that some patients are walking up and down the halls, while others need help just getting out of bed. When a nurse refers to someone as a "walkie-talkie," it’s actually good news.

This informal expression refers to patients who can walk on their own, use the bathroom without assistance, and handle most basic tasks independently. It’s not an official medical term, of course, but it’s commonly used among healthcare workers because it quickly tells the next shift that the patient requires less hands-on care than many others.

As nurses change shifts, you’ll often hear them give a quick report about each patient. One person may only need medication, while another is described as a "total."

The term is short for a patient who requires total care. They may need help eating, bathing, getting dressed, turning in bed, or moving from one place to another. Although the expression sounds impersonal, it’s simply a practical way for caregivers to communicate how much assistance someone needs.

Most people hear "frequent flyer" and think of an airline reward program. And that’s correct, but in an emergency room, the phrase has a very different meaning.

A frequent flyer is an informal nickname for patients who repeatedly return to the hospital, often due to chronic illness, recurring medical conditions, or other ongoing health issues. Behind the light-hearted nickname is often a difficult reality. Many of these patients are simply dealing with medical problems that require regular emergency care, and the expression is just a way to make the experience a bit lighter among the familiar faces of doctors and nurses.

Not all codes are for patients. The next time you’re in a hospital, look closely at what the nurse is pushing from room to room. It may look like a small rolling desk with a computer on top. Staff often call it a "WOW," short for "workstation on wheels."

As hospitals switched from paper charts to electronic medical records, these mobile computers became essential. Nurses use them to review test results, scan medications, update patient charts, and check doctors’ orders without leaving the bedside. The name sounds funny, but the technology helps caregivers spend more time with patients instead of walking back and forth to a nursing station.

After getting a shot or having blood drawn, most patients never think about where the used needle ends up. It certainly doesn't go into an ordinary trash can.

Hospitals place needles, scalpels, and other sharp medical instruments into special containers designed to prevent accidental injuries. These sturdy, puncture-resistant boxes are sealed when full and safely disposed of in accordance with strict health regulations. This not only protects nurses, but it also protects cleaning crews, waste handlers, and even the public from dangerous needle sticks. It’s one of the most important safety measures in every hospital, even though most patients never notice it.

If you’ve ever watched a medical drama, you've probably seen a patient become so agitated that several staff members rush into the room. In situations like that, a doctor or nurse may ask for a "B-52." But the name has nothing to do with numbers themselves; it actually comes from a medicine.

B-52 is hospital slang for a fast-acting injection used to calm down patients who are severely combative or at risk of harming themselves or others. The nickname comes from a commonly used combination of medications that usually include diphenhydramine, haloperidol, and lorazepam. It’s strictly reserved for when other methods of calming the patient haven’t worked.
