People are sharing the most random facts they know. Here are 15 of the most intriguing.
An 18" pizza is more than double the size of a 12" pizza.
The Hindenburg disaster, a slice of pizza and a squirrel.
How is it that some people seem to know a lot of random facts and are great at trivia, while others can’t get a question right while watching “Jeopardy!”? A big reason is curiosity. People interested in many different subjects have a more significant knowledge base than those who do not.
Further, when people are genuinely interested in a subject, they retain knowledge much better than if they heard the information in passing. So, while two students may learn the same thing in class, the genuinely interested one will remember the information, while the other will quickly forget it.
Studies show that curiosity is one of the most significant predictors of having a high IQ.
A Redditor named TechSavvy_Ryan asked the curious folks on the platform to share the facts that “most people don’t know.” The post went viral, inspiring over 8,000 responses in just two days. So, we cobbled together a list of the 15 most intriguing facts so you can wow people at your next trivia night or cocktail party.
1. Hindenburg survivors
"Most the people involved in the Hindenburg disaster lived." — CaligulaMonkey
"It was said 62 of the 97 people survived. You can see them running away in the nick of time as they touched the ground." — Rook2Pawn
2. Freaky fish
"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." — NikkiRex
3. Dangerous laughter
"You can collapse your lungs from laughing." — ContentTask2032
"So you can technically die from laughing?" -PaptaLopikju-
4. Dark side of cruises
"The amount of murder, rape and suicide that happens on cruise ships. Most of them unresolved, too." — PeacefulKillah
"Most newer cruise ships also operate an onboard morgue, as they are now considered cheaper options to retirement homes. Last time I was on a cruise, a crew member let slip that there were 2 deaths from natural causes." — Kegman83
5. Happy birthday
"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." — ItsMeCourtney
6. Burial facts
"A burial plot is called a graveyard if it's part of a church lot. It's called a cemetery if separate." — Missusmidas
"The backyard is only a graveyard if they can find the body." — Diels_Alder
7. Spanish Africa
"The only Spanish-speaking country in Africa is Equatorial Guinea. Its capital, Malabo, is on an island slightly northwest of the country’s mainland." — Dre_Lake
8. A case of bad nerves
"If your nerve is broken in the wrong way, the nerve will send a pain signal to the brain and it won't stop." — RhiannonCrystalLady
9. Pizza truth
"An 18-inch pizza is more than two 12-inch pizzas. 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." — Who_Else_But_Macho
"Not only that but if you assume that each pizza has a 1" wide crust all the way around, the 18-inch pizza is 79% toppings and 21% crust, while the two 12-inch pizzas are only 70% toppings and 30% crust. So not only do you get MORE pizza, you get a more efficient pizza with a greater toppings-to-crust ratio." — Tajwriggly
10. Declare your pacemaker
"When a body is to be cremated, the funeral director will first ensure that any rubber sole shoes, watches, phones, glasses, and sealed glass/metal containers are removed. Any sealed container becomes a pressure vessel when exposed to temperatures exceeding 1000°c. These will explode and do significant damage to the crematorium. This is the same reason why any electrical devices or items with batteries are removed, including most watches, and also pacemakers. When an undertaker asks whether your loved on had any medical implants or pacemakers, this is the reason why.
Glasses often tend to leave a silica residue on the bottom of the cremator which is just awkward to clean up and can build over time. Rubber soles are just incredibly polluting and are often not caught by the many filtration systems. This usually results in a black plume of smoke coming from the chimneys. Also, all metal residues and materials which are collected after the cremation is completed are gathered up and can either be returned to the family (upon request) or else treated and recycled, with proceeds from the recycling going towards a worthy charity." — Flaky_Tumbleweed
11. Scuba or S.C.U.B.A.?
"Scuba is an acronym, standing for self-contained underwater breathing apparatus." — JackCooper_7274
12. Squirrel speed
"Squirrels run faster up trees than on flat surfaces." — sstebbinss
13. Battleships
"Battleships in museums/ on display that are WW2 and later cannot start their engines because they have preservative grease inside in case the Navy has to bring the ship back into service." — Stravata
14. Sharkgevity
"Sharks predate trees." — External_Crazy_6568
"Well duh, they're predators." — Flowcahrt83
15. Code-shifting cells
"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." — Chipperland4471
"Now your fishes will be warmed."
"To have one’s eyes lined with ham."
"To lay your head in water."
"Repetition teaches the donkey."
"I only understand train station."
"To speak directly from the liver."
"Horse horse, tiger tiger."

Thank goodness this story has a happy ending.
There's a reason why some people can perfectly copy accents, and others can't
Turns out, there's a neurodivergent link.
A woman in black long sleeve shirt stands in front of mirror.
Have you ever had that friend who goes on vacation for four days to London and comes back with a full-on Queen's English posh accent? "Oooh I left my brolly in the loo," they say, and you respond, "But you're from Colorado!" Well, there are reasons they (and many of us) do that, and usually it's on a pretty subconscious level.
It's called "accent mirroring," and it's actually quite common with people who are neurodivergent, particularly those with ADHD (Attention Deficit Hyperactivity Disorder). According Neurolaunch, the self-described "Free Mental Health Library," "Accent mirroring, also known as accent adaptation or phonetic convergence, is the tendency to unconsciously adopt the accent or speech patterns of those around us. This linguistic chameleon effect is not unique to individuals with ADHD, but it appears to be more pronounced and frequent in this population."
Essentially, when people have conversations, we're constantly "scanning" for information—not just the words we're absorbing, but the inflection and tone. "When we hear an accent, our brains automatically analyze and categorize the phonetic features, prosody, and intonation patterns," writes Neurolaunch. For most, this does result in copying the accent of the person with whom we're speaking. But those with ADHD might be more sensitive to auditory cues. This, "coupled with a reduced ability to filter out or inhibit the impulse to mimic…could potentially explain the increased tendency for accent mirroring."
While the article explains further research is needed, they distinctly state that, "Accent mirroring in individuals with ADHD often manifests as an unconscious mimicry of accents in social situations. This can range from subtle shifts in pronunciation to more noticeable changes in intonation and speech rhythm. For example, a person with ADHD might find themselves unconsciously adopting a Southern drawl when conversing with someone from Texas, even if they’ve never lived in the South themselves."
People are having their say online. On the subreddit r/ADHDWomen, a thread began: "Taking on accents is an ADHD thing?" The OP shares, "My whole life, I've picked up accents. I, myself, never noticed, but everyone around me would be like, 'Why are you talking like that??' It could be after I watched a show or movie with an accent or after I've traveled somewhere with a different accent than my 'normal.'
They continue, "Apparently, I pick it up fast, but it fades out slowly. Today... I'm scrolling Instagram, I watch a reel from a comedian couple (Darcy and Jeremy. IYKYK) about how Darcy (ADHD) picks up accents everywhere they go. It's called ADHD Mirroring??? And it's another way of masking."
(The OP is referring to Darcy Michaels and his husband Jeremy Baer, who are both touring comedians based in Canada.)
Hundreds of people on the Reddit thread alone seem to relate. One comments, "Omfg I've done this my whole life; I'll even pick up on the pauses/spaces when I'm talking to someone who is ESL—but English is my first language lol."
Sometimes, it can be a real issue for those around the chameleon. "I accidentally mimicked a waitress's weird laugh one time. As soon as she was out of earshot, my family started to reprimand me, but I was already like 'oh my god I don’t know why I did that, I feel so bad.'"
Many commenters on TikTok were shocked to find out this can be a sign of ADHD. One jokes, "Omg, yes, at a store the cashier was talking to me and she was French. She's like 'Oh are you French too? No, I'm not lol. I'm very east coast Canada."
And some people just embrace it and make it work for them. "I mirror their words or phrase! I’m 30. I realized I start calling everyone sweetie cause my manager does & I work at coffee shop."
