10 basic things every adult should know but a scary amount don't.

When you think about it, 18 years really isn't a lot of time to learn all the things you need to know before you move into adulthood. Any parent or caregiver can attest that the first five years of a child's life is spent trying to make sure they don't accidentally seriously maim themselves, or worse. But just when you think that stage has passed, it rears its underdeveloped frontal cortex again in the early teen years. That doesn't leave much time for solidifying all the "common knowledge" things parents need to teach their kids before they move out.


Someone on Reddit asked the question, "What's some basic knowledge that a scary amount of people don't know?" and the people did not disappoint. Or maybe they did disappoint since this is about things that should be common sense, but aren't. Either way, the people on Reddit had a lot to say about the things that should've been learned before adulthood and some of them may surprise even the adultiest adult. There were more than 28,000 responses. Here's the top 10…

1. Water and grease don't mix.

This little bit of advice seems like a no-brainer until you add in the element of fire. One commenter explained that you should never put water on a grease fire, which can go against some people's instinct when they see a fire blazing. A grease fire can occur when you're cooking with something that requires grease, such as fried chicken or sauteed vegetables. The grease catches a flame under the pan and whoosh, you no longer have eyebrows. Grease fires are best smothered with a lid, or a substance like flour, salt or whatever is inside fire extinguishers.

2. Mixing cleaning products can be deadly.

Most people know not to mix bleach and ammonia, but not everyone knows not to mix other cleaning Items together. A commenter reminded people that mixing bleach and Pine-Sol can create toxic fumes that can absolutely be deadly if too much of the fumes build up in the room. Someone else chimed in that mixing any cleaning solutions together is not a good idea unless you're a chemist and know exactly which compounds are safe to mix.

3. Having a basic knowledge of female anatomy is helpful.

Surprisingly, or maybe not surprisingly, a lot of people don't seem to know that people with female anatomy do not in fact urinate out of their actual vagina. There was some confusion as to where it actually come from and for some users the Pikachu shocked face was definitely happening on the other side of the screen. If you are also unaware, I won't tell. Just lean in close so no one else hears. There's a small hole above the vagina called a urethra. That's where pee comes from.

4. Don't believe natural always means good for you.

This little tidbit of information may make some people upset, but one user said, "Just because it's natural doesn't mean it is automatically healthy. Just because it is artificial or synthetic doesn't mean it is automatically bad for you." Lots of things are natural that are not good for you, for instance, arsenic. It's certainly natural, but I wouldn't be in a rush test its healing properties.

5. If you're being questioned, the police are not your friend.

Maybe some people missed this in TV shows centered around law enforcement, but as one commenter helpfully pointed out, "cops can lie to you." They can, they will and they do. Police officers are allowed to make up anything they want in an effort to gather information from someone who could be a person of interest. The advice under this comment is to ask for a lawyer and invoke your right to remain silent.

6. How to spot an obvious scam.

You'd think if it was obvious then people wouldn't fall for it, but the truth is, scammers have been getting more and more clever. According to commenters, people have been posting about falling for scams that involve a fake astronaut and one where they send you money only for you to send it back, so in turn they send you a larger amount. There's even one where people call you and have more information than they should but then they demand you pay off your debt in Apple gift cards. Some of these may be really obvious to some people, but to others, fear kicks in and they do what they're told, which is what the scammers are banking on.

7. Accounting for the weight a semi-truck carries.

We've all seen it happen, someone cuts in front of a semi-truck and slows down or slams on brakes because they didn't realize there was a slower car in front of the truck. This is dangerous and can be deadly. One Reddit user is imploring people to know how long it takes for a semi-truck to stop and hundreds of others are nodding their heads in agreement.

8. How to tell if your food has gone bad.

Ahh, the old sniff test. One commenter used to work at a meat department and says he would regularly get phone calls from people asking how to tell if their food had gone bad. Though the person didn't have a "smellophone" to help answer the callers' questions, he does make a good point by saying everyone should know how to tell if their meat or food has gone past the point of no return.

9. Not all news online is real.

Remember back in the day when our parents were super skeptical of this wizardry known as the internet and would wag their finger saying "don't believe everything you read on the internet"? I do. The funny thing is, it was probably much safer to believe what was on the internet in the early days of the world wide web than it is now. Not all news sites are created equal and some sites deliberately put out false and inflammatory information. Deciphering what's true and untrue is a skill everyone should hone.

10. Evidenced-based reading should be focused more heavily on in high school.

Researching information on the internet isn't enough if you don't know how to search for and read scholarly peer-reviewed articles. Not only should you know how to read scholarly articles, but you should also know how to read the research included in the articles. The commenters feel that this skill will help people stay educated and better able to decipher truth in things shared online.

While some of these things may seem like common sense to you, they're not common sense to everyone. Hopefully someone learned something new today. If you want the nearly 30,000 responses, you can see them here.

34 broken bones, a mural, and Buddy the Elf—what these three things have in common
True

The Bank of America Chicago Marathon took place on Sunday, October 12th. Every runner who took on the enormous feat of 26.2 miles is truly an inspiration. We’re proud to share three outstanding stories about the power of community, giving back and crossing the finish line. Not only did they run an outstanding distance, but they each also gave back by fundraising for an organization that changes lives for the better.

Running a marathon is so much more than race day. It’s sticking to a schedule, getting enough rest, learning how to fuel your body for long distances, and—perhaps the most challenging of all—building mental resilience.



Meet Leanne: Running after 34 Bone Fractures

Leanne was only 12 years old when during her middle school cross country practice, she fractured her right tibia, the shin bone in her leg. This wasn’t Leanne’s first time breaking a bone—it was actually her 34th fracture. After many years of being overlooked as "clumsy," Leanne felt immense relief and recognition when a doctor diagnosed her with brittle bone disease, an incredibly rare condition.

Lurie Children’s provided a care plan for Leanne to build strength and start running again. And as of October 12th, Leanne ran her second Bank of America Chicago Marathon. She said in an interview, “I never thought I’d run again. But against the odds, here I am, training for my second Bank of America Chicago Marathon... all because of Lurie Children’s.”

Leanne’s impressive journey is a testament to the incredible research of Lurie Children’s, where she gives back by volunteering at the hospital and running on its behalf. Talk about being a true inspiration.


Meet Everett: Running to Inspire Through Art

Everett is an artist who creates beautiful murals around the city of Chicago. He uses his art as a tool for storytelling for community and connection.

In addition to being an artist, Everett is a runner. He ran the 2025 Bank of America Chicago Marathon on behalf of Peace Runners 773, a non-profit organization that strengthens the community of Chicago. In this video, we follow Everett on a run to visit some of his favorite murals. The run ends at Garfield Park, where Everett just finished a mural that he dedicated to the organization—symbolizing growth, strength and togetherness. Everett didn’t stop there.

While building his strength as a runner, Everett is strengthening his city of Chicago. Through his running and artwork, Everett has brought more awareness and resources to his community.

Meet Joseph: Running on Behalf of Special Olympics


Joseph ran the Chicago Marathon on behalf of Special Olympics, dedicating each mile to one of 26 friends with a developmental disability. The last 1.2 miles were extra special. It was for one of his closest friends, Matt.

In this video, Joseph runs to Matt’s house. For every mile of this training run, he tells us a heartwarming anecdote about Matt. They met at camp and soon, Matt will be a groomsman in Joseph’s wedding. The duo even sends a Christmas card every year—most notably dressing up as Buddy the Elf and sharing a bowl of spaghetti with maple syrup (spoiler: it doesn’t taste good).

As Joseph runs, he says, “Before we get to Matt, a quick note about why I’m running on behalf of Special Olympics. Matt and I love sports. And so do many of my other friends. Donations help provide year-round sports training and competition for more than 20,000 people with intellectual disabilities across Illinois.”

Joseph is the perfect example of inspiration. Not only did he run an entire marathon, but he also found inspiration in his friends who love sports as much as he does.


Leanne, Everett and Joseph are three incredible people who have shown how much strength and perseverance it takes to run a marathon. Each runner is both empowering themselves and their community. Their dedication to the Bank of America Chicago Marathon shows that the people of Chicago have a passion for the city, their neighbors and their personal achievements.

90-10 rule, happiness, life hacks, woman happy, woman angry, blonde woman

A woman is both happy and angry.

In the field of human psychology, there is a popular concept known as the illusion of control, which states that people believe they have greater control over the events in their lives than they do. If you think about it, a lot of our lives are controlled by chance, whether it's our genetics, the families we were born into, the time and place where we were born, and chance encounters that change the trajectory of our lives, such as the moment we met our spouse or someone with a job opportunity.

People who have it good are more likely to attribute their good fortunes to their effort, while those who are having difficulty getting by are more likely to blame bad luck. No matter how we delude ourselves, one thing is certain: many situations we find ourselves in throughout life are out of our control, and our real power lies in our ability to react.


Knowing how to react to situations beyond our control is the crux of the 90-10 rule.

What is the 90-10 rule?

The 90-10 rule, attributed to Stephen Covey in the bestseller “7 Habits of Highly Effective People,” states that 10% of life is made up of what happens to you, and 90% is decided by how you react.

People often explain the 90-10 rule by sharing a story of a mishap at breakfast.

You are having breakfast in business attire, and your young daughter spills coffee on your shirt. You reprimand her and your spouse for putting the cup of coffee too close to the table's ledge. Your daughter gets upset and misses her school bus. So you have to drive her to school, and because you’re speeding, you get a $180 ticket. You arrive at work late, and the day spirals from there. When you get home from work, you have an annoyed wife and child.

Why did you have a bad day?

A) Did the coffee cause it?

B) Did your daughter cause it?

C) Did the policeman cause it?

D) Did you cause it?

The answer is "D".

In an alternative universe, the coffee spills on your shirt, and you forgive your daughter. You change your shirt, your daughter makes the bus, and you get to work five minutes early. Now, instead of having a day that spiraled out of control, taking a moment to see the spilled coffee as an accident changed the entire day.

What happens when people skillfully respond to events out of their control over a long period? Their lives will be completely different than if they chose to take things out of their control personally.

Here are 3 ways to apply the 90-10 rule.

The key is not to take minor inconveniences personally.

1. If someone says something negative about you, do not be a sponge. Let the attack roll off like water off a duck's back. You do not have to let the negative comments affect you.

2. If someone cuts you off in traffic, don’t take it personally; who cares if you get to work 10 seconds later? There's no point in letting it ruin your day.

3. If you get to the airport and find out your flight is delayed, don’t get mad at the person working at the ticket counter. It’s beyond their control. The plane will arrive at some point, whether you get worked up or not.

The 90-10 rule mirrors the "Let them" theory championed by Mel Robbins, a podcast host, author, motivational speaker, and former lawyer. The first thing is to acknowledge that others are imperfect and that you cannot change them. “People can only meet you as deeply as they've met themselves. Most people haven't gone to therapy, they haven't looked at their issues, and frankly, they don't want to. Let them. Let your parents be less than what you deserved," Robbins said in a viral video. "Let your family life be something that isn't a fairy tale. Try to remind yourself that they're just doing the best they can with the resources and the life experiences they have."

Remember, you can’t control everything, but you can choose how you react to minor annoyances. Choose to respond in a skillful, thoughtful manner without taking things seriously, and you can quickly get past the minor annoyances without causing the adverse ripple effect that can ruin your entire day.

Pency Lucero taking in the Northern Lights

Seeing the northern lights is a common bucket list adventure for many people. After all, it ticks a lot of boxes—being a dazzling light show, rich historical experience and scientific phenomenon all rolled into one. Plus there’s the uncertainty of it all, never quite knowing if you’ll witness a vivid streak of otherworldly colors dance across the sky…or simply see an oddly colored cloud. It’s nature’s slot machine, if you will.

Traveler and content creator Pency Lucero was willing to take that gamble. After thorough research, she stumbled upon an Airbnb in Rörbäck, Sweden, with an actual picture of the northern lights shining above the cabin in the listing. With that kind of photo evidence, she felt good about her odds.

However, as soon as she landed, snow began falling so hard that the entire sky was “barely visible,” she told Upworthy. Martin, the Airbnb host, was nonetheless determined to do everything he could to ensure his guests got to see the spectacle, even offering to wake Lucero up in the middle of the night if he saw anything.

Then one night, the knock came.

It looks better in person

In a video Lucero posted to TikTok, which now has over 12 million views, we hear Martin ushering her out to take a peek. Then we see Lucero’s face light up just before seeing the sky do the same.

“I thought it was a prank,” the onscreen text reads in the clip. “And then I see it….”

“I was mostly in awe of what this Earth is capable of,” Lucero recalled. “I never expected it to be THAT beautiful for the naked eye.” This is a hopeful sentiment against the widely accepted notion that the northern lights are often better looking in photos than they are in real life.

As Lucero asserted in a follow-up video, “Our video doesn’t do it justice at all…I would argue it’s even better for the naked eye.”

Others were quick to back Lucero with anecdotes of their own experience. “It’s definitely possible to see it like in the pics. I saw it this winter in Norway, there was bright green, purple and so much movement.”

“They’re so much better in person, the way they dance and move around is insane and beautiful.”

Of course, if you ask Martin, who everyone agreed was the best host ever, seeing guest reactions of pure wonder and joy is even “better than the lights themselves.” But still, he can’t deny that there’s a breathtaking magic to it all. He shared with Upworthy that “Sometimes it feels like it will pull you up in the sky like you are in the middle of it. I wish everyone would have the chance to witness it.”

When it comes to tips for actually seeing the northern lights, Martin admits it still mostly comes down to being in the right place at the right time. Luckily, his Airbnb listing can help with that.

What causes the northern lights?

The Northern Lights, scientifically known as Aurora Borealis, occur when charged particles from the sun collide with the atmosphere near the poles. The charged particles interact with gases such as nitrogen and oxygen to produce credible, colorful light displays that float magnificently above the night sky. The Northern Lights are most visible in high-latitude regions such as Sweden, Finland, Norway, Iceland, Alaska, and Canada.

Nature has a great way of reminding us that, beyond the distractions and distresses of modern life, there is sublime beauty waiting for the chance to capture our hearts.

This 4-year-old’s hilarious reaction coming home from school is all of us

This little boy is not shy about expressing his exhaustion, and it's incredibly relatable.

A little boy speaks to the camera

There's one thing you can say about little kids that's pretty consistent no matter who the kid is, and it's that they're brutally honest. Whether you have something stuck in your teeth or you've gained weight, a small child will inform you - loudly, and usually in front of others. But one preschooler's moment of honesty is going viral for how relatable it is.

An exhausted and cranky 4-year-old named Jude has had enough. The little boy had just gotten home from school when he must've been asked something before the camera started rolling because his response was a #same moment.


"Listen. No, do you hear me? I'm cranky, I'm tired, I worked hard at school," Jude says to his dad.

Jude's mom, Amber Tinker uploaded the video to TikTok where it went viral with over 14 million views and over 1.5 million likes. The tiny grumpy human was clearly not interested in whatever shenanigans his dad was up to and he let him know it.

Jude's dad, Justin Tinker was attempting to tease the boy about messing with him later but Jude was having none of it. The preschooler quickly repeated that he was cranky and tired after working hard at school. He mumbles something as he walks towards a barn when his dad stops him.

"I've already got everything fed and watered. I already got the eggs, I did your job cause I knew you was tired," Justin calls out.

Though his dad did his chores for him, Jude still didn't feel like he got his point across because later in the video he repeats how cranky and tired he is. Both of his parents explained they also worked hard today and were tired but it was obvious that Jude out tired them all. In the end he declared he was getting a bath tonight. Maybe his mom will bring him a cold Capri Sun and light some candles while he soaks in a bubble bath. Preschool must be rough these days.
