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?

If you want to stop and have a chat, you won't die if you move out of the walkway.
If you move to the side, a piano might fall on your head.
This is definitely false. If you move out o the walkway, you will likely be in the road, where there is a very good chance that you could be deleted.
Obviously no one is suggesting you move your conversation into street traffic. Most sidewalks have 2 sides: the dangerous side such as the road or a cliff or a river and the safe side such as a building or a park. Just step out of people's way for the duration of your conversation. Safely.

My fav ever was the discovery that highlighting a word and pressing shift+F3 will change the word between all caps, no caps, and just the first letter capitalised.
I wish. Like many of the other things here, it depends on the program you're in. It works in Microsoft Wordpad (my usual program unless I need more bells and whistles), but it doesn't work in Firefox, Thunderbird, or Open Office Writer.

A burial plot is called a graveyard if it's part of a church lot. It's called a cemetery if separate.
According to various definitions I'd rate this as 'mostly true. True in that graveyard is more commonly associated with a church, but untrue in that both words are technically correct whether or not a church grounds is involved. So not a great hill for the grammar nazis to die on (pun intended). --- "The word cemetery (from Greek κοιμητήριον 'sleeping place') implies that the land is specifically designated as a burial ground and originally applied to the Roman catacombs. The term graveyard is often used interchangeably with cemetery, but a graveyard primarily refers to a burial ground within a churchyard."
Is this just in English or other languages too? There's no difference in my language (cemetery - cimitir)
We in german have the word "Friedhof" (Peace Yard; literally) for both, but I'm actually not sure if there would be another word in that context that maybe isn't very common
Load More Replies...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.

Nah. More like an overlapping Venn diagram. Biology includes some chemistry but not all of the field of biology is chemistry. Behavior and distribution are just two of the parts of biology that are not chemistry. "the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution."
each level you move up, the more each category overlaps. at GCSE, they're more distinct. at A level, Biology has a lot of Chemistry, and Chemistry is basically Physics.
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!
Did you know Tuba is also an acronym? It stands for "terrible underwater breathing apparatus"
Many people (including my younger self) are also mistaken about what is inside the breathing apparatus. No, it's not oxygen, because 100% oxygen would kill us. It's just compressed air.
Yes and no. A lot of people are mistaken about the standard (insofar as there is one) gas for SCUBA, but many gas mixtures besides regular air are used. Recreational divers often use Enriched Air Nitrox (commonly referred to as just "nitrox" though nitrox is really any mixture of nitrogen and oxygen).Enriched Air Nitrox is air that has a higher than normal percentage of O2 to reduce the uptake of nitrogen during the dive, which extends he allowable duration of the dive. Technical divers often use "trimix" with is O2, N2 and helium. Decompression divers often use pure O2 or high % O2 mixes to speed the offgassing of N2. O2 is toxic at high partial pressures, s the amount of O2 in the mix determines the maximum depth at which it can be used. Pure O2 is used for the final (and long) stage of decompression at 20'.

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?
On the 22th of September, 2015, a USA Federal Judge, George King, ruled that the Warner/Chappell copyright claim over the lyrics was invalid. He determined they had the copyright over a very specific arrangement of the music for piano. The tune had previously been used for the song, "Good Morning to All".

Public domain. There were always questions about the song’s origins and the right to a copyright it in the first place.
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.

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! 😂
Load More Replies...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
Load More Replies...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.
Load More Replies...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.
Load More Replies...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.
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.

- 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.

Squirrels run faster up trees than on flat surfaces.
It's probably more difficult for anyone to run up a flat surface.
Could be lots of reasons, my best guess is that on a tree, all claws are full engaged in the bark giving an absolute push off - on flat surfaces- think of your dog trying to scramble on waxed linoleum...

Font describes the variation in style in which something is written: size, italic, bold, all caps etc.
Typeface is the variation in the style of letters (Arial, Times New Roman, Comic Sans) that most people refer to as fonts.
If you're interested in fonts, read the book Font Psychology: Why Fonts Matter and How They Influence Consumer Behavior by Richard G. Lewis. Quite interesting.
"Typeface" hasn't been used in a LONG time. Modern software usually lists it as "font" regardless.
Upper case - taken from the upper case of letters. Lower case - taken from the lower case of letters. Both from the printing world, the lower case letters were used far more frequently so they were stored in the case closer to the typesetter who picked the individual letters to make up the lines that were then stacked into forms for printing.
These terms are related to metal typesetting. With the rise of IT, font has been used interchangeably (and in German font is used for typeface - highlighting for font [typography-terms for use with software publishing]). In typography itself, font is a complete character set in a particular point size, in a particular typeface. I hope it's not too confusing, but publishing changed completely while the art, rules and terms of "setting text" are roughly the same.
And the origin of this use of the word "font" ? Which originally meant "source", from "fountain"? From the days of "print" - which meant lead cast type, ink, and paper...
While I'm not disputing the fact, in my experience font was commonly used to refer to the typeface in casual use when I was involved in some smaller scale publishing. I think it's a bit like when someone tries to tell you Kleenex is a specific brand and you should say tissue. It's true, but a lot of folks are going to say Kleenex (or same for Q-tips) anyway.
Not according to the Oxford English Dictionary, which gives "typeface" as a synonym for "font".
The OED evolves, slowly, but it does evolve. When I was in HS (in the early 70's) , I was in printing using cold type. The "font" was the package of individual letters, the "type", that was then distributed into the "job cases" for hand setting the cold type into a composing stick. The typeface was the style of the type.
Load More Replies...That's because typewriters haven't been used in forever, and typeset (cast) hasn't been used in longer than that. Font covers the specific set and the adjacent bells and whistles now, mostly universally.
Most the people involved in the Hindenburg disaster lived.
the last survivor of this disaster died 08 nov 2019, Werner Gustav Doehner. hr was 8 years old when he was on her.
97 people were on board; 35 people died and the others survived. One person on the ground was also killed.
I seem to remember reading somewhere the Empire State Building in NY was set up so that the Hindenburg could dock at the top.
True, and I did not know that. Additional statistics on the deaths are interesting too.
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.
Those tributaries count as part of the 4000 mile length so you correct in the right/wrong analysis.
Load More Replies...The two biggest reasons are 1)most of the Amazon basin doesn't have roads to connect that would need a bridge and 2)the river's width varies greatly from season to season. It can go from 4-5km at its widest to 50km in weeks during the wet season. The Amazon delta where it dumps into the ocean is 320km wide and a 100 km deep and it constantly changes.

An 18 inch pizza is more than two 12 inch pizzas.
And to do the math, the surface area of a circle is pi x r squared.
Pi is the constant. 18 in pizza has a 9 in radius, or r. 12 inch has
6. 9 squared is 81, 6 squared is 36. 36 x 2 is 72. 81 is greater than 72.
Many pizza menus don't take this into consideration, so, for example a 30cm pizza that costs chf20 is 7 cents per square cm, a 40cm at chf30 is only 5 cents per sq cm. (Prices from dominos.ch)
Oh, I 100% guarantee they did the math. It's just the volume discount, as usual.
Load More Replies...I was under the impression that there would be no math today.
More cleverly...if the radius is z and the height is a, then the volume of the pizza is "Pi *z*z* a".
Load More Replies...Another factor - both sizes of pizza probably have roughly the same amount of 'dead zone' out by the crust edge so the sauce and toppings don't fall off in the oven. So that bigger pizza not only has more total area, it probably also has a greater percentage of it with toppings. But I'm not going to try to bother with the math to verify that.
You only need to do the math if you want to quantify it precisely. The crust is normally the same width, so it increases in direct proportion to the radius, while the saucy part of the pizza increases as the square of the radius.
Load More Replies...If you want to compare relative sizes (area), just square the diamteter. A 10" pie gives 100, and a 14" pie gives you 196. So, quite quickly you know that a 14" is about twice (196%) of a 10". 18^2 = 324, 12^2 = 144, double that 288, which is less than 324.

If your nerve is broken in the wrong way, the nerve will send a pain signal to the brain and it won't stop.
My best friend's daughter has extreme nerve damage in her stomach area, and is literally in constant pain. She's outlived doctor estimates from sheer cussedness.

Load More Replies...I seem to recall another BP article that said it was the lack of signal that caused the pain. I'm a bit fuzzy on it but the gist as I recall is that your brain is used to receiving a constant signal from any given nerve and having that signal disconnected is perceived as pain. It seems counter intuitive to me so the answer is probably deeper than that. It was part of an article about why people with amputations feel 'pain' in their hand / foot / whatever that is no longer part of their body.
Basically, pain is strange (heck there’s even a book about pain called that). Chronic pain is classed as nociceptive pain - there is no structural damage to nerves or tissue/bone, but the CNS has become sensitised and so produces pain before there is any need to protect by pain.

My friend has CRPS and the pain and experiences is excruciating. Look it up, it’s higher on the pain scale than giving unplanned birth or having a finger amputated.
CRPS is fascinating (although not if you have to live with it) because of the physiological changes that take place in the affected area/limb. Hair growth changes and nail growth changes, the limb is a different colour/temperature. There’s been recent research investigating the role of immunoglobulins in causing it (injected into mice who developed symptoms, they’ve also demonstrated that with fibromyalgia too)

Centralia PA, Its a ghost town in Pennsylvania. Somehow they managed to set a coal mine on fire and its been burning since 1962. There are still a few people living there apparently but there are noxious fumes venting out of the ground so the government doesn't allow new people to go there.
"somehow they managed" - mine fires are an ancient problem - there's one in Australia they think is 6,000 years old.
Super interesting! “Located under Mount Wingen in the state of New South Wales (Wingen means 'fire' in the language of the local Wanaruah people, the traditional custodians of the land), this underground smolder is a coal seam fire – one of thousands burning at any one time around the globe. Once ignited, these subterranean fires are almost impossible to put out. Slowly but intensely, they travel through the coal seam, a layer of coal that naturally occurs beneath Earth's surface.“ https://www.sciencealert.com/this-mysterious-fire-in-australia-has-been-burning-non-stop-for-at-least-6-000-years
Load More Replies..."Somehow" - they were using a former pit-mine as the town trash dump. They thought they'd sealed it completely before converting it but they hadn't. It didn't matter until one Memorial Day in the 60s when they mayor decided the dump was an eye sore for all their planned celebrations so he instructed crews to burn it. They set it on fire and turned out they hadn't sealed it well enough, the fire had gotten into a mine shaft under the pit and started to spread. From there it was very largest the fault of the state govt failing to invest the money needed to do the job properly of finding out where the fire was located and putting it out.
There's tons of mine fires from centuries to even millennia ago still burning. 1962 is downright recent compared to some of them! Lignite burns very slowly!
Someone set a pile of trash on fire too close to a crack leading down to the coal seam they were mining. It spread down into the mine. They didn't take it seriously at first, and didn't take action quick enough. Due to the properties of the coal, it's nearly impossible to put the fire out at the moment, so it will be expected to burn for another few hundred years or so....
Centralia is also super disappointing. No visible sign of any mine fires, and just trash everywhere from people partying and leaving all their rubbish behind. The graffiti road was pretty cool though.

The bow-wow theory of language (aka the onomatopoeic theory), which states that our imitation of natural sounds is the basis of language development.
I always thought this was so interesting :) kind of reminds me of how multiple languages consider cats to say “meow” or some similar variation (“miao,” “mau,” etc)
Not sure whether the bow wow theory holds up. There is a theory that different sounds are created and learned as an infant gains more and more control over their mouth, tongue and vocal cords. The easiest sound to make is a "ma" sound which is why the word for mother is practically every language is an "M" word. Similarly, the "da" (or "pa") sound is the next one controlled therefore fathers are mostly "D" or "P" words. Seems more likely that we make sounds naturally and they just organically evolved as our vocal systems got more complex.

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.
Ocular immune privilege, still not fully or mostly understood, we do know it performs this task quite well. This also makes eyes a great way to research therapies, because the immune response is localized, sometimes immediate and easy to track. The eyes aren't the only part that have this, though they do have a more extensive "system" of their own (using local mechanisms and global, meaning, outside of their system). A pregnant uterus, the testis and some areas of the brain also have this sort of function to better protect themselves and the rest of your body too. If you have an eye that has never functioned it's possible that eye and it's little quirky system can misfire and determine your functional eye (or even another part of you) is an enemy that must be destroyed, immediately, should you get an infection or injury. Makes for some interesting research, but not at all fun for me, lol.
Every time I read this fact, I have one question: Why the eyes? Why would that be the part of the body that can be destroyed by it's own body?
Autoimmune diseases are fascinating. The immune system is fascinating!
So. Very. True. I had a scratched cornea from work one time - did not know it at the moment, but flooding my eye with water did *not* solve the issue. Boss refused to let me to seek medical treatment, so since I worked in a Mall I went to the optometrist on my lunch break. He grimaced, and ooohhh'd and awwww'd, and said I had to immediately go see his ophthalmologist buddy. I told him my boss wouldn't let me go, maybe I could call in sick tomorrow and go see him. Nope, damage would already be done. I was a dumb 21yr old and should have left and filed worker's comp, but instead, I couldn't take it anymore at one point, yelled at my boss for being an overbearing bsturd, went home and put on my sleep mask so I'd stop blinking constantly and slept as long as I could. Luckily, it didn't get infected, or I'd have been effed.
Always prioritize health. When you see what damaged health can do to someone, you understand that nothing else matters
Load More Replies...I can verify this to be true. I scratched my cornea in 2013. Long story short, 7 surgeries (including 2 cornea transplants), 1 eyeball rupture, and I am blind in my left eye. I now wear a prosthetic shell.
Recently read a story that mentioned a stomach problem ended up affecting the eyes. Didn't mention the separate immune system. Now the fact of a stomach problem causing eye problems makes sense.
After eye muscle surgery I noticed a bump in the white of my eye and told my wife. She said that while I was in the recovery room my doctor did the final adjustment and then plunged the fishhook-looking surgical needle into the white of my eye and tied it off. I guess I was still half asleep but no pain cells in the eye? It was a bit freaky but I'd do it again.
Sharks predate trees.
bull sharks are the only dangerous species of shark that can acclimate to fresh water. a bull shark was caught in 1995, 930 miles up the mississippi river near st. louis! and in australia, carbrooke golf course has a large water hazard/lake on the 14th hole that has several bull sharks that were swept into the lake from a river that overflowed its banks.
Although, there are no domcumented instances where any shark has leapt out of the water to attack a tree. (Yet)

Alogn these lines:grass is a real newcomer. Notice you never see it in documentaries about dinosaurs. Think how much of the world is covered in grass; consider that grass is more drought tolerant, and then think how much of the world would be desert but for grass.
This is a perfect example of why things like grammar and spelling matter. Sharks may pre-date trees, but they sure don't predate them.
1916 Mattawan Creek, off the Jersey shore, had a great white which killed a few people.
The chances of a good recovery after CPR is abysmal.
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.
As doctor Mike Said, chest compressions!

We also have defibrillators in public spaces. You phone the number on the box, get the code to open the machine, and the operator talks you through using the machine. Whilst this is happening, an ambulance is despatched. The distance/time to get to hospital is much smaller than in other countries. Because of all of these factors, when a person starts CPR, the patient has a 300% - 1000% higher rate of survival than in the neighbouring countries.
May I ask which country? My country has many public defibrillator boxes, but BH I’ve never had to use one. Most public buildings I see have at least one.
Load More Replies...ITYM the chances of recovery after a heart attack in general. They're certainly higher if you get CPR than if you don't.
In voluntary firefighter training we were also trained in CPR by the city's first responders, and were told: If after a heart attack, everything is handled well (defibrillator immediately, ambulance within 15 minutes and immediate hospital care) the survival rate is only 50%... So if you ever need to apply your CPR-knowledge, do what you can, but don't feel guilty if the patient doesn't make it.
Load More Replies...Depends on the circumstances. If arrest occurs under anaesthesia, outcomes can be generally good depending upon patient age. Since oxygen and IV access are already present, everything happens much faster.
Last I read, CPR has about a 10% success rate outside of a hospital. In a hospital at the hands of a skilled team, it's closer to 22%. But just because you get the heart beating doesn't mean all is well. It's very easy to arrest again, and it will certainly happen again if the underlying problem isn't dealt with. If the person goes down and CPR isn't started immediately (a lot of times a bystander finds the person down and calls EMS), then there's a good chance the brain will be irreversibly damaged.
The same thing goes for animals. Please don't feel guilted into checking that "yes' to CPR in the event somethng goes south when you drop off your animal for surgery . The odds are abysmal also, and most folks don't have pet insurance to cover the cost of it, which can quickly become a LOT.
Anyone who wants an elderly family member to receive CPR (Chest Compressions) has never seen the aftermath - it's awful.
Less than 50% and it doesn't matter what you do for CPR, you are breathing into a dead person so any chance is better than none
I read that breathing air into the person’s lungs is no longer recommended and chest compressions are what you need to focus on. Stopping to do mouth-to-mouth interrupts your chest compressions, which are most important.

The tip of a shoelace is called an aglet.
Great, now I'm singing the Phineas and Ferb aglet song. (https://www.youtube.com/watch?v=r_DuY0CQUz4&ab_channel=DisneyXD)
This was a Jeopardy show a few weeks ago. A contestant answered it correctly. So I've now heard the word 'aglet' twice this year whereas I can bet $ I'd not heard the word even once in decades.
Which isn't a lot, but it's weird it happened twice.
Load More Replies...For some reason my last two puppies have been fascinated by the aglets. They won't chew the shoes, they won't chew the shoelaces, but they crunch the damned aglets off every single shoelace they could find.
Water doesn't conduct electricity.
Edit cuz I should probably explain; pure water doesn't conduct electricity. Getting water to that level of purity is relatively costly however.
Adding any salt (ionic compound) will make water conduct electricity. These salts are referred to as electrolytes.
And pure water is bad for you. Contrary to some myths drinking a glass of it won't kill you. But truly pure water strips electrolytes from your body. So drinking too much will definitely harm you.
Load More Replies...Electrical discharge machining (EDM) is usually done in a bath of deionized water for this very reason.
So what you're saying is that the vast majority of water on earth will in fact conduct electricity
Yes, water is a poor conductor, it's the stuff that is in it (salt, for instance) that conducts.
PFAS are a type of fluoride chemical, adding fluoride to water should never have been allowed but now PFAS are stacking with all the other fluoride people are exposed to, we need a universal fluoride/fluorine ban. https://www.texastribune.org/2024/04/16/texas-pfas-forever-chemicals-public-water-systems-epa-limit/ https://www.youtube.com/watch?v=-hvhAEiB19M
If you get a tooth abscess on the maxillary (top arch) canine to canine. It needs to be taken care of ASAP. The area is called the triangle of death when it comes to abscess or infections.

i honestly thought that mirror was actually a hook that was pulling the teeth up. Yikes
Also sinus infections, which can lead to bacterial meningitis, which can lead to death.
I just had a lot of dental work done and my dentist told me if I hadn't gotten this procedure done, the infection would've killed me.
when I was little, my mum had a root abcess in this area. if she pressed on her swollen face, it left dents where she pressed. when it burst, the smell was horrific. she later needed a root canal, and I remember the huge black stitches she had on her gums.
Also don't pick at sores in that area as it could shoot infection straight to the brain.
Gosh, good thing dental care is so cheap in the U.S., especially with insurance. /s
As someone who has four root canals in that area, I can attest! I nearly wound up in the hospital if my dentist had not done an emergency root canal on a Sunday! The cause of all four root canals was an upper jaw injury.
Why is the dentist using the mirror to look at the part of the tooth they can already see?

A broken clock is right twice a day, but a clock ticking in reverse is correct FOUR times a day.
peckx063 explained:
Start one at midnight going forward and one backward. After six hours they'll both be at 6, after another six hours they'll both be at 12, after another six hours they'll both be at 6,after another six hours they'll both be at 12.
And technically nearly all clocks that are not broken or running backwards are correct less than twice a day (depending on how far off their reckoning of a second is). At least if you're comparing to the international atomic clock down to the femptosecond or less.
The problem is that you will not know when it is telling the right time unless you have another clock to compare it with.
Sir, I'll have you know that this is the Internet!

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.
Lungs can also just spontaneously collapse. Risk factors include being a tall, skinny man, and certain other conditions like vascular EDS. It happens a fair amount in teenage boys for no reason other than existence. It’s very treatable, with some evidence suggesting in mild spontaneous pneumothoraxes, the best course of action is watching and waiting (per NEJM), but chest tubes and even surgery can be used in more severe cases. Reoccurrence is relatively common, but surgery lowers that risk. My dad just had his second in 5 weeks.
Load More Replies...Not exactly a myth. Here’s an article about Pilgaard-Dahl syndrome, AKA “Laughter-Induced Pneumothorax,” AKA a collapsed lung from laughter. To be fair, this isn’t something that can just randomly happen to anyone. “The syndrome consists of laughter-induced pneumothorax in smoking middle-aged men when exposed to hearty humour.” https://pubmed.ncbi.nlm.nih.gov/21156116/
Load More Replies...I once had a lung collapse while I was sitting down stretching. I was stretching up, with my arms above my head and got this incredible pain in my chest area. I walked around for a couple of days before being convinced to go to hospital emergency room. This was years ago when my asthma was not being controlled well. I was not having an asthma attack that day, but just sitting down writing a letter. I NEVER let my asthma get bad for more than a couple of days now, then a trip to an urgent care center for an x-ray.
When I first watched Finding Nemo I couldn't breathe for quite a long time when Doreen started 'talking' to the whale. I laughed so hard for so long!
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.
The movie The Fifth Element is the only movie to reach general audiences, in which the protagonist and antagonist are never made aware of one another, let alone meet on screen.
Domestic cats have what's known as a "Non-Fatal Terminal Velocity". Which means that, provided they are of healthy age and weight, you could punt one out of a 747 at cruising altitude and it would hit the earth with no measurable damage.
To temporarily reduce, or remove entirely, the symptoms of tinnitus, cover your ears with your palms as hard as you can, and ensure you middle fingers are touching behind your head, then rapidly tap the entire length of your fingers against the base of your skull.

The dropped cat one isn't true either. An animal has to as small as a mouse to survive a drop from a 747. Even a rat is too big and will die.

Load More Replies...I'm not sure the Fifth Element one is right. I mean the antagonist is approaching from space as some sort of nebulous threat. But they are aware that it's approaching. While they never meet it as such surely that counts as being aware of it? And I'd say Lord of the Rings is the same. Frodo never meets Sauron, he's just a nebulous threat in the background. All the actual interactions are with minions, just like Fifth Element...

Can confirm the cat thing... yesterday, my cat accidentally fell from the 3rd floor. Not even a scratch - she was a little scared, but otherwise completely unharmed.
So happy your cat is fine 😘 But one case doesn't prove a theory.
Load More Replies...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.
Except - the first premise is flat not true. Wishful thinking. Your body does NOT "know" what to do with every possible- disease - totally novel diseases exist, and are not in your database.
And the only way for your body to "learn" is by experiencing the pathogen... Either by infection or vaccination.
Load More Replies...Ok, this isn't exactly correct. The genetics of our immune system are heckin lit, and come with a ton of ways to create antibodies to just about everything infectious we might encounter, but not to everything. There's a region in the genes of antibodies called the hypervariable region that frequently mutate in order to bind to diverse antigens, and do a pretty darn good job at helping the adaptive system to recognize many, many kinds of antigens. However, there are some antigen 'shapes' that your specific antibody genes just can't recognize. Sort of like an immune blind spot. And this is true for everyone. So there are always some antigens that our specific immune systems won't respond to. I mean, it covers most infections, just not 100%. Which is still pretty damn impressive!
So we could be immune to everything except we have an inefficient filing system?
Eh, it just the time it takes to find the cell. If it takes too long it can be deadly

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.
