Did you know that crows hold what essentially are funerals? Yeah, hundreds of them flock to the location, but avoid the body and don’t scavenge it. It’s thought that this may be a kind of survival strategy, to make sure that they avoid potential threats even if food is plentiful where the crow’s body was found.
That’s probably something ornithologists (bird scientists) know. Turns out there are a lot of facts only specialists know! Let’s take a look at some of them as shared by Redditors.
More info: Reddit
#1 Always Keep 2 Exits In Mind
People almost always try to exit through the same door they entered. In a crowded venue ALWAYS take a second to find your exit and then find a second exit. Mark them in your brain just in case. In an emergency most of the crowd is going to go for the main door they came in through. Knowing where another exit is can save your life.

#2 Give Truckers Some Breathing Room, Unless...
Trucker here and we don't want to be anywhere near you either.Go around or stay back don't just ride right beside us. We can't see you very well when you are beside us and if s**t happens you're gonna go splat.
It is very very very rare that any driver wants to slow you down it's not like we get our rocks off on making you late. We work extremely long hours on very little sleep and we just wanna get where we are going without getting in an accident and killing someone.
Trust me if we could go faster we damn sure would.
Also if you give us the fist pump to honk our horn you just made our whole week. That's one of the greatest joys in a truckers life.
Be safe out there!!
Edit: A reoccurring comment is that most of you get it and are very cool but you hate when a truck driver hops in the hammer lane when you're trying to pass them at a reasonable speed. I'm with you on that and Im here to tell you most truck drivers are not a******s like that and the real truckers hate the ones that are. Every profession has a group of a******s that ruin it for the good ones.
Edit Edit: This has gotten an unexpectedly high response and I really appreciate all of you joining in the conversation. If we would all just communicate like this more often we could solve a lot of problems in this world.

#3 Movie Horses Deserve Better
In movies they unnecessarily yank on horses’ reins, practically ripping their mouths out. Anytime you see their mouths open with the bit pulled way back in there, they’re not having fun and it’s for no reason other than maybe drama and the trainers are s****y for letting that happen.

#4 Being Nice Will Open Far More Doors Than Being A Douche Canoe
Being nice and patient will give you a bigger chance of getting a refund or a new of whatever is broken, than being angry and blaming the random worker.

#5 Trees Don't Have Magic Regeneration Powers, Actually
Trees do not heal through regeneration like people think they do.They quite literally just grow over it. The tree can close the wound off in a way not really visible to us but it will never grow back that same tissue in the same way like we would when we cut ourselves.
It would be like growing a second layer of skin over a cut and never really healing the cut. Your body would make it stop bleeding but you’d alway be able to see your cut if you peel the layers of skin that grew over top.
Trees are like onions, just like Ogres! They have layers.
I always think of a jaw breaker when I work with trees.
Did anyone get my Shrek reference? I should go to bed now.

#6 Before You Attack A Manufacturer, Make Sure You Know That Transparent Isn't The Same As Transclucent
I work in acrylic sheet.The number of people who do not understand what translucent means is astounding.
Translucent =/= Transparent. Translucent is SOLID color that allows light transmission- it glows. Transparent is just that..transparent.
We have customers call us All. The. Time. Telling us we filled an order wrong, that they received “a solid color and ordered translucent red”.
**EDIT: thanks for all the upvotes and thoughts!
For clarification, majority of these customers order online either through our website or Etsy. Both sites have dozens of pictures and videos explaining and showing the differences!

#8 High-End Neighborhoods Are Often Built With Low-End Quality
Those "high end" or "expensive" neighborhoods they slap up really fast... Usually, gated communities and other semi-exclusive suburbs full of McMansions are built with the absolute cheapest materials and poorest quality/ untrained labor.Never buy a "spec" home without some serious research into what you're actually buying. All that "luxury" is barely surface deep.

#10 Main Character Animals In Documentaries Are Played By Several "Actors"
In any given nature documentary, the protagonist animal you’re rooting for is ‘played’ by several different ‘actors’ - i.e. that one brown bear’s story is patched together from footage of a bunch of different bears. And in about 90% of the ‘animal reacting’ shots they’re reacting to the camera crew. Nature documentaries are heavily constructed.

#12 If You Get Prescription Antibiotics, Finish The Whole Course
You need to finish the entire course of the antibiotics you were prescribed. You don’t suddenly stop taking them after you start feeling better.#13 Just Because You May Have Had Bedbugs, Doesn't Mean You're An Awful Person
Bed bugs don’t make you a nasty person with a nasty home. An infestation isn’t due to a sanitation issue. They’re an imported pest, which means they hitched a ride on something you brought into the house. Usually luggage or furniture

#14 Websites Aren't Slow Because Of Poor Programming, But Rather All The Ads And Trackers
If a website is slow there’s a big change it’s not because the developers did a bad job but because marketing insisted on putting dozens of trackers and ads on it.#15 Protect Your Hearing At All Costs, Especially When You're In Places Like Broadway
When you go out to clubs or any place with some sort of "strip" (aka Broadway in nashville) the volume is 11 times out of ten too loud. I work at barstool occasionally as AV and at night it's gotten up to 110-115 DB. For reference, the threshold of pain is 120 db. Wear hearing protection people. You can't get that s**t back.#16 Shock Old Veggies In Ice Water
If you have sad vegetables(carrots celery)or lettuce that look wilted not bad you can make them crunchy by shocking in ice water.

#17 When Elevators Fail, They Go Up
An elevator will go up to the top of the hoist instead of crash to the floor in most catastrophic failures due to the counter weights.

#18 If There's So Much Oxygen In Rocks, Why Don't They Float?
Volumetricly, most rocks are made of mostly oxygen. Most of the entire Earth (crust and mantle) is also nearly half oxygen (by mass).If you've ever read "OxYgeN DisCoVeReD on mOOn!" ... It's rocks. It means they've discovered rocks.

#19 Archaeologists Care More About The Where, Rather Than The What
In Archaeology, it’s super awesome and great that you brought stuff to an archaeologist at a local dig site near you of things you found in your backyard or nearby asking us appraise it - but the thing is, we’re actually more interested in the context the item(s) are found. We need/want to see the bigger picture. Arrowheads, flintknaps, trade beads, etc are super cool but they are worth so much more when we can tell if they are part of a hoard, burials site, ceremonial site, etc.

#20 Turns Out The ER Is For Emergencies, Who Could Have Guessed
The ER is there to keep you from having a catastrophic outcome in the next few hours/days (or next few minutes, in some cases.) If nothing irreversible is going to happen for several days, they don’t really care what the problem is.#21 Explosives Are Shy, So They Need Another, Smaller Explosive To Go Off With Them
Powerful explosives are so insensitive to shock that it usually takes a smaller, more sensitive explosive to set them off.

#22 UTIs May Have Some Surprising Symptoms
UTIs will often cause confusion in people over 70.Eta:
UTI is Urinary Tract Infection and some people can get confused to the point of hallucinations and delirium. It can cause increased weakness which also leads to falls.

#25 There Is No Less Grim Way To Calculate The Damage Of Severe Burns
Generally speaking, if you add the percentage of the body covered in 3rd degree burns and the persons age together you get the likelihood of it being a fatal burn.32 and 40% burn coverage? about 70% of people in that condition will die.
Source: Firey, working closely with several doctors from burns units.
Edit: I love the 100 year old people comments and the people with 0% burns but in thier 30s lamenting the 40% death chance.

Urban heat kills way more people in Australia than bushfires. In the 2009 Black Saturday bishfires in Victoria, 173 people died in the fires, but over 300 died of the heat prior to that.Also, most of those deaths occur at night, not during th day.

#31 Cement? Nope, That's Concrete, Baby!
Cement and concrete are not the same thing. Cement is the main ingredient in concrete, but concrete is the whole mixture of cement, sand, aggregate, water, etc.

#32 A "Fractured" Bone Is As Good As A "Broken" Bone
There is no "fractured" vs "broken" there are only different types of fractures. It's really a semantic problem but patients get heated about it.

#33 A Little Bit Of Pain May Be An Indication Of Something Far Bigger
Pain is effectively a psychological phenomenon and a terrible indicator of physical injury.Far too many people think the human body is a simple cause and effect model (it hurts therefore something where the pain is located must be 'wrong'). Instead it is much more like a set of wildly complex, interdependent systems like climate or stock markets. A lot of medical diagnosis is educated guessing with an overreliance on singular labels for the benefit of explaining the situation to the patient.

#34 Credit Is Not The Same As Debit!
Credit and debit are different. I could not believe how many people did not understand this.

#35 Lab-Grown Diamonds Are Cheaper Than Companies Let On
Lab grown diamonds cost $2 per ct. Of electricity to grow. The "value" price has absolutely plummeted on them the last 2 years. Most especially the last 8 months. Don't overpay on them as they all perform. 1 cts currently 6-800. So for the first time in the history of the jewelry world you can officially buy moissanites from "high end" brands that are more expensive than their lab grown diamonds of same quality. ?The amount of people robbed of value the last 2 years is in the millions and dollar amount unfathomable. Had a guy as recent as March spend $24,000 on a 3 ct. Lab grown online when I was finding them for $5500 at the time. Places are rushing to make money back from buying in bulk. There will be a documentary about this some day.

#37 You May Try To Fool Them, But Garbagemen Know Better
We have cameras that can see what is in your trash as we dump it. Some companies even take snap shots of every can's contents to catch hazmat items. They bill the city, with the address it came from, and the city could follow up with the homeowner for reimbursement if they choose.How crappy, in general, people are at making sure they are recycling the right items and properly cleaning some of their items before putting them in the recycling bin.
We remember the houses with issues, people that try to double dump, overfill, and dump hazmat. We watch for those offenders specifically.
We will pull out cans for handicapped people, dump them, and put them back. You have to call and have that setup though.
The garbage man knows whats going on in your neighborhood, almost as well as the mailman.
#38 Pilots Do A Lot More Work Than People Give Them Credit For
A lot of people think that commercial aircraft “fly themselves.”In truth, all takeoffs are flown manually by the pilots as are the vast majority of landings. The autopilot is advanced in a lot of aircraft, but it also screws up often and without warning.
#39 More Goes On Behind The Scenes Than You May Think
It takes a small army a week to shoot a 30-second commercial.#40 Digital Cameras Are Funky
The sensors in digital cameras (including phones) are monochromatic (they don’t “see” color) and have a tiny color filter on each sensor element so it can detect one of three colors (red, green, blue). Then the image is created by calculating what the other two colors might be based on one color value and the values of the nearest sensors around it. tldr; 2/3 of the color in a digital photo is calculated from the 1/3 that is actual data.

#42 Less Is More When It Comes To Syrup In Drinks
When I worked as a barista: how much f*****g syrup is in flavored drinks. At the cafe I worked at, we measured flavoring by grams. If you got a large mocha, that m**********r would have like 110grams of chocolate sauce in it.
If you want a little bit of flavor, I suggest only 1 pump. 2 max.

#43 A Traffic Light Does More Math In A Day Than I Do In A Week
A traffic light changing colors at an intersection involves lots of math. The amount of time it stays as a yellow light followed by it turning red at which point all directions will be red for a period of 1-3 seconds is all done by specific calculations. Everything is taken into consideration for it when all the lights are red for that brief second - how many meters/feet is the intersection, what is the speed limit vs the actual travelling speed, average amount of cars that pass that spot in an hour, following distance, the grade of the road if it's on a 1% incline it'll be different timing than of it were on a 2% incline.#44 Nothing Is Completely Safe, Nor Will It Ever Be
Programming/Hacking. Many companies pride themselves on being extremely secure and "un-hackable" to an extent- they also advertise that if you use their service your assets are super secure and nothing will/could ever happen.In reality everything can be exploited. Nothing is completely safe and nothing probably will ever be completely safe.
Another one which I really wish more people knew is that- anyone who encounters a person that calls themselves a "hacker" all of a sudden becomes scared of their capabilities. "I better not p**s this person off otherwise they'll ruin my life" in reality only a small portion of hackers actually have the knowledge to do something that would influence your life in a very bad way. Most people who call themselves hackers barely know anything and can only pull off a few tricks others find very intimidating. The biggest tool these types of people have are scare tactics- using simple tricks that others find very intimidating can get them very far.
Dont get my wrong though- you do get hackers who can influence your life in a very big negative way but its very rare and most of the people who have this knowledge dont care enough to put in the effort to hack you unless you're someone very important.
#45 Geneticists Avoid Letting Parents Know That Their Kid May Actually Not Be Related To Them
Genetics: there's a bunch of stuff we don't report back because they're considered incidental findings.This can include genetic diseases with no treatment/mitigation.
Or non-paternity. If your kid is sick with a genetic disease and you go get genetic testing done for mom, dad and little timmy, we do not automatically report back if dad is no relation or is actually an uncle.
At the same time in most places you have the right to request your data.

#47 Opposite Sides Of 6-Sided Dice Always Add Up To 7
The opposite sides of a die should always add up to seven. On a craps table, you'll see the "stick" dealer bring the dice to the middle of the table and separate them corner to corner. This is so the person sitting down (box supervisor) can verify with the mirror opposite of them that the opposite sides total seven.2/5 1/6 3/4
Source: 14+ years of dealing table games.
Edit: Apologies. I should've included "sides of a six-sided die".
