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.

The truth about your brain

You won’t believe what happens in your brain while you sleep

Your brain is one of the most powerful and mysterious organs in your body. It controls everything from your thoughts to your emotions and even processes information at lightning speed. But how much do you really know about it? Some long-believed myths about the brain have been debunked, while other surprising facts reveal just how incredible this organ truly is. Get ready to be amazed by these fascinating brain facts!

You’ve probably heard this one before, but it’s completely false! While it’s true that not all parts of the brain fire at the same time, imaging studies show that most regions are active throughout the day, even when we sleep.

Your brain is constantly working, controlling bodily functions and emotions, and processing information. So next time someone says you’re only using 10% of your brain, you can confidently tell them that’s just a myth!

Here’s a weird fact: While your brain processes pain signals from the rest of your body, it has no pain receptors of its own. This is why surgeons can perform brain surgery on conscious patients without causing them pain.

However, the membranes and tissues surrounding the brain do have pain receptors, which is why headaches and brain injuries can be so excruciating.

How come we have headaches if the brain has no pain receptors? Well, that’s because headaches are triggered by chemical activity in the brain, changes in nerves and blood vessels, and even fluctuating serotonin levels.

In some cases, hormones like estrogen can also play a role, which explains why migraines are more common in women.

Dreams are proof that your brain never rests! (Warning: this fact can make you feel exhausted.) While you sleep, your limbic system, that is, the part of the brain that deals with emotions, becomes especially active, which is why dreams often feel so intense.

On average, humans experience four to seven dreams per night, even if we don’t always remember them. And what about that scary nightmare about falling? Well, you can thank your amygdala, the brain’s fear center, for that one.

Have you ever walked into a room and instantly forgotten what you were after? That’s because short-term memory only lasts about 20-30 seconds! That’s not enough!

Your brain holds a limited amount of information in its active state before deciding whether to store it or discard it. Ironically, we can’t really choose what makes the cut, but we do hope these facts stay with you!

That sharp, icy pain when you eat something too cold? It’s your brain’s way of telling you to slow down! Officially called sphenopalatine ganglioneuralgia, a brain freeze happens when cold food or drinks rapidly chill the blood vessels in your throat, causing them to constrict and then rapidly expand. This sends pain signals to your brain, warning you of the sudden temperature shift. It’s annoying, but it’s actually your body trying to protect itself!

You didn’t need us to tell you, but let’s look at the details: The average person has between 12,000 and 60,000 thoughts per day. What’s even more interesting? 95% of those thoughts are the same ones you had yesterday. Is that not surprising enough? Hear this out: 80% of them tend to be negative. That’s because our brains are wired for survival, constantly analyzing risks and potential dangers.

Even though it only makes up about 2% of your body weight, your brain employs a major quantity of energy! It consumes 20% of your oxygen and blood supply, making it one of the most demanding organs in your body.

If your brain goes without oxygen for just five minutes, brain cells start dying, leading to irreversible damage. This is why deep breathing and cardiovascular exercise are great for brain health!

Do you know that feeling when you hit the back of your head and see stars? That’s because your occipital lobe, which controls vision, is located at the back of your brain. If you get hit there, your brain momentarily misfires, causing flashes of light.

Interestingly, your brain processes vision on the opposite side; while your right brain controls your left eye, your left brain controls your right eye. It’s one of the many ways the brain operates in a complex way.

Believe it or not, your brain generates between 12 and 25 watts of electricity when you’re awake. If you can’t really grasp how powerful that is, check this out: It’s enough to power a small light bulb! Your brain’s electrical activity is what allows neurons to send signals at speeds of up to 260 miles per hour.

Your brain may be the fattiest organ in your body, consisting of at least 60% fat! This is why consuming healthy fats, like omega-3s and omega-6s present in fish, for example, is essential for brain health.

Healthy fats stabilize brain cell walls, reduce inflammation, and support cognitive function. So go ahead and enjoy that avocado toast, it’s food for your brain!

It’s not just your memory that fades over time; the brain itself physically shrinks as one gets older. It continues developing until your late 40s, but after that, it slowly decreases in size.

Now, size doesn’t equal intelligence, so a smaller brain doesn’t necessarily mean a less capable one. Staying mentally active, exercising, and eating brain-boosting foods can help keep it in top shape!

We often think of cholesterol as bad, but your brain actually depends on it! In fact, 25% of your body’s cholesterol is stored in your brain, where it helps with learning and memory. However, unlike other organs, the brain can’t absorb cholesterol from the blood, it has to produce its own. So, while too much cholesterol in the body can be harmful, the right amount is vital for brain function. At least you can use that as an excuse to get that burger!
