Knowledge is something that can always be improved. At the same time, it's also a thing that no matter how much effort you put in, you'll have some blind spots because it's impossible to know absolutely everything, isn't it? There are things that we are doomed to never learn about. But today's list isn't about them. Instead, it's about the things many people don't know but can learn about. And when is a better time to start than now?

A burial plot is called a graveyard if it's part of a church lot. It's called a cemetery if separate.
What a grave thing that people get wrong. But, pray tell, since I'm dying to know, are those definitions are set in stone, or if they are just a rough plot of an idea? I might have to do some digging into the topic myself though. You can't trust everything you see on the Internet, keep that in your memory (I'm sorry, but I'm an amateur dad joker).
Probably many of us have heard the saying that “knowledge is power” at least once in our lifetime. This phrase comes from the Latin aphorism "scientia potentia est" (the words can be placed slightly differently, but it doesn’t change the meaning). Commonly, it’s attributed to Sir Francis Bacon, former Lord High Chancellor of Great Britain, as the expression "ipsa scientia potestas est" ('knowledge itself is power') occurred in his book “Meditationes Sacrae” (1597).
As you can see, Francis Bacon didn’t use the exact aphorism that’s assigned to the “knowledge is power” saying. The first time this exact Latin phrase was written was in the 1668 version of “Leviathan” by Thomas Hobbes, an ex-secretary to F. Bacon.

Scuba is an acronym, standing for self contained underwater breathing apparatus.
I swear I learnt this from a TV show...I want to say Boy Meets World but I may be wrong, something of that era!
A company called Warner Chappell Music collected licensing fees for use of the song “Happy Birthday to You” all the way until 2015. That’s why characters in movies often sing other songs like “For He’s a Jolly Good Fellow” and restaurant chains often have their own birthday songs they sing to customers.
I knew the song was still under copyright. Is it still, or did it go public domain in 2015?
Yet, even though knowledge is power, everyone carries different levels of it. And this leads to the phenomenon of the “curse of knowledge” or “the curse of expertise.” It’s a cognitive bias where people incorrectly assume that everyone knows as much as they do on a certain topic. This makes it hard for them to imagine what it’s like to not have that knowledge.
One of the most interesting experiments done about this curse, which also quite easily explains the phenomenon, was conducted in 1990 by a Stanford University psychology graduate student Elizabeth Newton. She created a game, where people were assigned roles of “tapper” and “listener.” Tappers had to tap out the rhythm of a well-known song on a table, while the listeners had to guess the song.
Out of 120 songs tapped out during the experiment, only 3 were guessed correctly. Yes, only 3! Apparently, when a tapper taps, they hear the tune in their mind along with the taps, while the listener only hears the uncoordinated tapping sounds. And due to the curse, the tappers couldn’t see why it was so hard for listeners to understand the tune.
Irukandji jellyfish grow only to about 1 cubic cm in size, but have an incredibly painful sting. One symptom of the sting is a strong impending sense of doom. Victims have begged their doctor to be killed as they were certain they would die anyways.
Mammals pee an average of 22 seconds, no matter if mouse or elephant.
My wife pees for about 2 seconds (I'm not even joking, she pisses so hard that I worry she's gonna chip the porcelain), I pee for about 2 minutes. I think both of us are upsetting the average.
It’s called a “power piśs” 😀 I had a delightfully weird female roommate once who actually practiced this and did kegels every day. We went camping a lot (in the bush, no toilets) and she was always so excited to make me listen to how fast she could pee when we took bathroom breaks together (bush safety rules). It was pretty impressive tbh! 😂

I'm so tired of seeing this. It is not true. TL:DR - bad science based on filming 32 animals where the actual number is 0 seconds to 48 seconds. One study (Yang, et al 2014) looked at 32 animals at a zoo and discovered they pissed 21 seconds +/- 13 seconds. One standard deviation means that 67% (21 of 32) pissed between 8 and 35 seconds. 95% pissed between 0 and 48 seconds. You wonder how 0 is possible. The study includes a graph showing it takes a rat .16 seconds.
I thought it couldn't be true, because to the best of my knowledge rodents don't have bladders, they just expel urine as and when it's created

I don't know how long I pee for, but I'm getting to the point where I have to pee *every* 22 seconds
Seems to be based on the much-hyped Yang etc al (2014), which says "all mammals above 3 kg in weight empty their bladders over nearly constant duration of 21 ± 13 s." Yes, that's remarkable consistency given the biological variance; still, plus or minus 13s per species (n = 32) plus the weight constraint suggest that it's probably not reliable. My own research (n = 1) suggests the variation in a single species can vary from a few seconds to at least several minutes depending on age, position, type and quantity or liquid consumed and the proximity of other species members.
Said paper explicitly said small mammals such as mice and rats don't pee this way, incidentally, but in frequent urination of single drops.

Curious about who funded the grant for that bit of research, who accepted the job, and why anyone thought it mattered enough for the effort? That's just how my stream of consciousness flows.
According to the authors, the main reason was that urination time is a very easy thing to observe and yet can be highly useful for diagnosing urological disorders "as well as inspiring the design of scalable hydrodynamic systems based on those in nature." Regarding the latter, "Engineers may apply this result to design a system of pipes and reservoirs for which the drainage time does not depend on system size. This concept of a scalable hydrodynamic system may be used in the design of portable reservoirs, such as water towers, water backpacks, and storage tanks." Funding was from an early career physics grant for the physical modelling and an undergraduate research award for the experiments.

Gonna time it. ed: Just shy of 15 and a half seconds. So a full bladder I could see going a fair bit beyond the average. Interesting! Also that's a lot of pee from an animal that's huge.
i thought that said that they pee every 22 seconds and i was like fricking hell
What a crock! Just watch your pets, kids, and listen to your coworkers.
Seems unbelievable that it takes the same time for a mouse and an elephant. But I'm not a scientist...
My late doggo would pee for so long that I could have a full conversation with the neighbors. LOL!
My Guinea pig could wee so quietly on my legs for half an hour and I thought she was just warm and comfy, so downvote for me !
This works with any other type of knowledge. Knowing some piece of information makes it hard to understand how others don’t know it, hence the curse in the phenomenon’s name.
And it’s not the only thing that's so cursed about it. In fact, this phenomenon creates quite a few problems between people:
- Makes some teachers have difficulty understanding how their students can’t comprehend a topic;
- Makes it difficult to communicate;
- Makes it hard to understand or justify your own past behavior;
- Makes it hard to predict or understand the behavior of others.
So, be aware that as you learn new things from this list, you might fall for the curse of knowledge. After all, as the question that prompted this thread suggests, the majority of people don’t know these facts, so don’t forget that!
Also, maybe you know any other facts that not many others know that weren't mentioned in this list? Share it with us in the comments! And don't forget to upvote the most interesting facts you learned from this list!

The Amazon River is over 4,000 miles long and doesn't have any bridges that cross it.
Technically, False. But also true. The Amazon river proper does not have any bridges. However, there are many small bridges crossing the distributaries, which are still part of the same river (as they leave and re-join the river). I know this for a fact because I have crossed them, just outside of Iquitos, Peru.

Your eyes have a separate immune system from the rest of your body. If they get damaged in such a way that it affects anything other than your eyes, your regular immune system can attack the damage and will not recognize them, meaning your own body can permanently blind you.
What's worse, your body cannot tell the difference between either eye. If one of them gets infected or damaged, your immune system can attack your healthy eye and take away your sight entirely.
Sharks predate trees.

CPR is to keep oxygen circulating until you can get actual medical help to restore a rhythm (if they even can). CPR alone isn't going to fix someone. Just keep someone's brain from dying from lack of oxygen.

You can collapse your lungs from laughing.
Not quite right. People with certain conditions can suffer a form of attack as a result of laughing (such as an asthmatic having an asthma attack, and narcoleptics falling asleep), and smokers can have a phlegmatic attack which can cause blockages in the lungs and airways. The act of laughing forces air from the lungs (including stale air), which is why a good laughing session always includes a large intake of breath. The collapsing of a lung occurs when air gets trapped between the lung and chest wall, which would not occur when laughing. *Unless there was another force/injury, such as a broken rib, which is rare, but possible.
The human body has no means of sensing "wetness", and thus doesn't know what "wetness" is. It can only sense temperature and pressure. Put on a latex glove and submerge your hand in water, and it will feel wet.

Your immune system has at least 1 cell to combat every single infection that could ever exist. Your T-cells are cells that, when created, go through a sort of training phase in the thymus where they are allowed to change their genetic code at random, in order to be able to battle 1 random very specific disease. During this, the body also kills any T-cells that are accidentally adapted to kill human cells. Then the T-cells are sent to lymph nodes, to be found later by presenting an antigen (a part of a pathogen) to it. Basically you have something for everything in your body, the problem is just finding it, as it takes a good few days for your body to locate the specific one.

Fact checking is a thing. If it isn't a fact didn't post it as one.
'Anyone can write on Bored Panda. Start writing!' That appears pretty obvious when you read this load of garbage. Most of it is inaccurate, at least the parts that were actually finished before posting it.
Fun fact: Humans are capable of natural flight, as long as they strongly disbelieve in the concept of gravity. That disbelief can be achieved under moments of extreme stress but also extreme ignorance and youth. Scientists have almost achieved results by dropping babies off of the Empire State building in a series of tests in the 1950s. Unfortunately due to the ratio of success/failure and the optics of the situation, they did not publish any of their research. Anti-flight authorities are still looking for them to this day. Believe it or not.
Just in case, I have to publicly state that this is complete sarcasm and should not be taken seriously. No babies have been harmed for this joke, but some intelligent people have hurt their eyes by rolling them.
