10 Curiosities You Probably Didn’t Learn in Biology Class

The world is a big, wonderful place full of facts we never thought possible. For instance, if a pregnant mouse has a sudden medical issue, the fetus will send stem cells to heal the mother, increasing its chances of survival as well. Fetal stem cells have been found in human mothers as well, dubbed by science as microchimerism.

Bright Side dug up some more marvelous facts about nature and its creations, upholding our yearly resolutions to spread knowledge and joy.

1. The heart slows when your face touches water.

As mammals, we can’t breathe underwater, so as part of the mammalian dive reflex, our heart rate goes down in the water — more so if we go underwater. Even splashing the face with water makes the heart slow down, making it a great way to calm down.

2. Fungus can break down plastic in weeks.

It is said that in the future, there may be more plastic in the ocean than fish. This is why the plastic-eating fungus is great news, and there are around 50 new species of such fungi discovered already. One of the fungi discovered can digest plastic within 2 months, so there’s hope for us yet.

3. Newborn babies can support their own weight.

Newborn babies are strong — strong enough to be able to grasp things in their tiny fists and even support their weight as shown by an experiment done in the nineteenth centuryLouis Robinson witnessed babies able to hang from a walking stick, from 10 seconds to 2 minutes and 35 seconds.

4. Koala fingerprints have been mistaken for human ones.

We’ve been told that our fingerprints are unique, and they are. But the fact remains that even though we share a common ancestor with the koala that was alive 100 million years ago, koala fingerprints look very similar to human fingerprints, as do chimpanzee fingerprints for that matter.

5. Snails can sleep for 3 years.

If you thought bears had it good with hibernation, meet the snail. Snails can sleep rather than hibernate for 3 years at a time without needing food. Of course, this is with some snail species, not all of them. Meanwhile, bears usually hibernate for just 4-8 months.

6. Sloths need 2 weeks to digest food.

Sloths don’t only move in slow motion — even their insides move slowly, ostensibly to preserve energy, which is why a sloth’s digestive system takes 2 weeks to process the food it ate. Plus, most of what it eats is indigestible, giving it very little energy from each slowly chewed mouthful.

On the other end of the spectrum lies the shrew, whose digestion takes mere minutes and is done so fast, not much of it is fully digested. This is the reason why shrews eat their own feces. They can die of starvation in a matter of hours if they don’t eat.

7. Your brain ignores seeing your nose.

We can see our nose all the time, it’s just that the brain tends to ignore it because it’s a constant visual stimulus. It’s the same with people who wear glasses. After a while, they simply stop noticing them.

8. Your forearm is the same length as your foot.

If you don’t have the time to try on a shoe, measure it from your elbow crease to your wrist. If it fits or is just a little smaller, it would fit your foot because the length of your forearm is the same as your foot. And this is just one of many human body ratios that are a marvel in themselves, including the fact that your femur bone is one-quarter your height.

9. You can “see” your white blood cells.

If you look up at a cloudless, bright blue sky and see some wiggly things at the periphery of your vision, you’ve just experienced the blue field entoptic phenomenon. The wiggly things are white blood cells moving in the fine blood vessels moving in front of the retina, at the back of the eye.

10. Human beings have striped skin, but only cats can see it.

Human beings have stripes and patterns on the skin too, and they are called Lines of Blaschko, name eponymously by the scientist who discovered them, Dr. Alfred Blaschko. These are closer to tiger stripes, forming more of a V-pattern fanning out from the center to the extremities. These lines are visible under UV light, a spectrum that cats can see too, which is why cats can see you as a striped being as well.

Which of these facts turned out to be a revelation for you? Share your extreme nature facts with us and blow us away.

Pampered Boy Ridicules Flight Attendant Unaware That His Wealthy Father Is Observing

Seventeen-year-old Andrew is used to getting what he wants and treating people badly when he doesn’t get it, but his father decides it’s time Andrew learned a lesson about respect when he mistreats a flight attendant.

“Do you think he’ll be okay?”

Steven had been watching his seventeen-year-old son walk toward the airport boarding gate, but now he looked down at his wife.

“Of course Andrew will be okay,” he replied.

“I hope this new school can help him learn some humility.”

“But what if they treat him badly in the dorms?” Steven’s wife looked up at him. “He’s never been to boarding school before.”

“That’s the point.” Steven clenched his jaw. “Andrew has become spoiled and he needs to learn some tough lessons about life.”

Months later, Andrew was flying home for the holidays after his first semester of boarding school. He’d hated every minute of his time there and was eager to return to his high-powered computer and the luxury car he got for his sixteenth birthday.

“Hey, you.” Andrew waved to the flight attendant, a redhead woman with freckles.

“How can I help you, sir?” The flight attendant smiled at him.

“You can get me something better to snack on than these peanuts.” Andrew threw the bag of peanuts at her.

The flight attendant’s smile turned into a frown. “Sir, please don’t throw things at me.”

“I’ll do what I like,” Andrew replied. “You’re here to serve me, so stop complaining and do your job.”

“Don’t talk to her like that.” The older man in the seat beside Andrew turned to look at him.

“Just because it’s her job to serve us doesn’t mean you can disrespect her.”

Andrew rolled his eyes and snapped his fingers at the flight attendant. “I’m still waiting for my snack.”

The flight attendant walked away with her eyes downcast. The older man in the next seat shook his head.

“Your parents must be so disappointed in you,” the elderly man muttered.

“Nobody asked you, old man.” Andrew began scrolling through the movie options.

After a few minutes, the flight attendant returned with a pretzel.

“Here you go, sir,” she said and held out the pretzel to him. “If there’s anything else —”

Andrew sneered and slapped the pretzel out of her hand. “I don’t want a pretzel!”

The flight attendant recoiled, tears forming in her eyes. “Peanuts and pretzels are the only snacks we serve on this flight.”

“That’s pathetic, just like you.” Andrew leaned forward in his seat. “Go and fetch me a proper snack, now!”

“How dare you talk to her like that?” A woman rose from her seat across the aisle and put a hand on the flight attendant’s arm.

“If she did her job then I wouldn’t have to.” Andrew pointed at the flight attendant.

“She’s a servant, and a bad one too.”

The flight attendant burst into tears. The woman passenger tried to comfort her.

“Somebody ought to give you a hiding, young man.” The elderly passenger in the seat next to Andrew scowled at him.

“I agree.” Somebody placed a hand on his shoulder.

At that moment, Andrew understood what his father had been trying to teach him.
Andrew recognized that voice. He turned and stared in surprise when he saw his dad behind him. His face was red with anger.

“Dad, what are you doing here?” Andrew asked.

“Flying home from a business trip,” Steven replied. “I hoped we might meet on the plane, but I never imagined it would be like this. Apologize to this young lady and the other passengers immediately.”

Andrew hunched his shoulders and mumbled an apology. He didn’t see what the big deal was, but he knew better than to disobey his father when he was so angry.

When Andrew and his father got home, Steven marched him straight to his office on the second floor of the luxurious house.

“This comes to an end right now.”

Steven shut the door and turned to point at Andrew. “Your behavior is disgusting. I hoped that you might learn manners in boarding school, but it seems I was wrong.”

“Why are you making such a big deal out of this?” Andrew threw out his arms. “She’s just a flight attendant. It’s not like she’s important.”

“And that’s your problem, Andrew. You think you’re better than others because you were born into a wealthy family, and that you can treat others badly because of that.” Steven crossed his arms. “That’s going to change.”

“What does that mean?”

“You won’t be going back to that school. You’ll finish your education at a public school, and you’re going to spend your holiday working.”

“Working?” Andrew straightened up. “Are you giving me a job at your company?”

Steven smiled. “You could say that. I’m going to give you a job in my cleaning company, as a janitor.”

Andrew was horrified.

“I won’t do it!”

“You will because I’m also cutting off all your privileges. I’m taking your bank cards, your computer, your car, and your cell phone. I’m even taking your branded clothes.” Steven put his hands on his hips. “You’re going to find out what it means to respect people.”

Andrew had no choice. His father took his possessions from him, and he started his job as an airport janitor the next day.

Andrew knew nothing about cleaning. The older woman he was assigned to work with laughed at him for not knowing how to sweep or mop. He shouted at her for laughing at him and threatened to get her fired.

“No, you won’t,” she replied, shaking her finger at him. “Your father warned me about you, now get to work. These floors don’t clean themselves.”

Andrew sighed and started sweeping. He was clumsy, and his supervisor teased him about it. Andrew got angry, but there was nothing he could do about it.

He was cleaning the trash cans when something hit him. He turned and saw that somebody had thrown an empty takeaway carton at him.

“Hey!” Andrew shouted at the man who’d thrown the carton. “How dare you throw that at me.”

The man ignored Andrew, so he ran after him and grabbed his arm.

“I’m talking to you,” Andrew said.

The man shook Andrew off so hard that he fell to the ground. “Get your filthy hands off me, you dirty janitor.”

Andrew watched the man walk away in shock. Was this how it felt to be treated like you didn’t matter? Andrew didn’t like it. He looked around just as somebody kicked him.

“Get out of the way, you lazy bum.” The woman who’d kicked him sneered at him.

“I’m going to report you for sleeping on the job.”

At that moment, Andrew understood what his father had been trying to teach him. He knew now how much it hurt to be mistreated by people who thought they were better than you.

A flash of red caught his eye, and Andrew looked up. He recognized the flight attendant he’d been rude to and hurried across to her.

“I’m so sorry,” he said when he reached her. “I treated you so badly.”

The woman was surprised to see him, but she smiled when he apologized.

“I’m glad you’ve learned the error of your ways,” she said.

What can we learn from this story?

Everyone deserves respect. It doesn’t matter if somebody works a menial job; they’re still a person and deserve to be treated respectfully.
Sometimes children need to learn a lesson the hard way. It can be difficult for children to understand the true depth of important life lessons when they’ve never experienced that situation.
