Imagine being hungry during the caveman days and contemplating whether or not you can eat that giant serpent that just slithered across your path.

Or being captivated by the brightness of a berry and assuming it is delicious enough to eat.

In both scenarios, you either lived to share your delectable discovery with others or died from ingesting something not meant for human consumption. That is, if you weren't consumed first.

Thanks to our intrepid ancestors who did all the hard work for us to determine what was good enough to eat, the only thing we need to worry about is the expiration date.

Curious to pick the brain of strangers, Redditor cplfromholland asked:

"What food has made you wonder: 'How did our ancestors discovered that this was edible?'"

Maybe The Third Time's A Charm

"Not exactly a common food, but was watching an episode of one of those survival shows that were popular several years ago. The guy was trying to survive in the South American rainforests and came across a kind of frond eaten by the locals."

"The part that caught me off guard was that he explained the frond couldn't be eaten raw. Trying to eat it uncooked would cause horrible digestive problems, namely diarrhea and cramps, It would be unpleasant but survivable. So the guy boils the frond... and explains that it's still inedible. In order to safely eat this frond you had to boil it once, toss the water out, and then boil it a second time before eating it."

"Some dude a long time ago had to trial and error his way through this; what motherf'ker was like 'yes this made me violently sh*t myself the last two times I tried it, but maybe this time will be different.'"


All Fish Are Not Created Equal

"Pufferfish. Generally they are extremely poisonous to humans and will cause paralysis or death. However, you can eat it if properly handled. How many people had to die to figure out which parts could be consumed and how they needed to be prepared."

"You still occasionally see people getting sick from eating it at restaurants now. If I recall correctly, I think I once read chefs who use it in Japan must take a written examination regarding the proper food care when handling it before being able to serve it. Absolutely wild to think people take the risk to eat it."


Hyper Goats


"Legend has it that it was goats. A farmer noticed his goats acting differently when eating a certain cherry, and somehow, processing, roasting, and grinding the beans to drink became quite a popular thing."


"That's correct as far as I'm aware - an Ethiopian goat farmer in the 9th century noticed his goats became more energetic after eating the coffee cherry. I'm not sure if he was the one that then took the beans, roasted them and brewed them, but Kaldi, the goat farmer is often attributed with the discovery of the elixir of life."


Edible-Nest Swiftlet

"How bout some bird-spit soup."


"In a few Asian countries, swifts nest are collected to make soup. Swifts build their nest with their spit. Their saliva is a delicacy in south east Asia and it is supposed to have multiple health benefits."


The Foulest Fruit

"Dudes - who the f'k cracked open a durian and decided that yes, I will eat the thing that smells of dead and onion."


"I got curious and bought one from Chinatown in NYC."

"The man selling it asked me with broken English and a shit eating grin 'you want me open this?' To which I replied 'no, I know what I'm buying.'"

"I opened it on my back porch and the smell made me gag. Tastes like onion custard. Wouldn't recommend."


"Cancer Lump"

"F'kin Cashews man. The process is so complicated. They grow on the underside of a fruit, like a single testicle w a lump of cancer on the end. Once you take the nut off, you have to fry it past 190 degrees Celsius to process the shells, because inside those shells is not only the cashew, but an extremely caustic acid that will burn you if not cooked out. Who the f'k wanted to eat the cancer lump that bad?"


"Anything that takes multiple steps to make it edible always makes me wonder who had the patience to figure out all the steps."


Fungus Among Us

Mushrooms, so many are poisonous, but someone kept trying h them."


"'All fungi are edible. Some fungi are only edible once.' - Terry Pratchett"


Aged Dairy

"A lot of dairy products.... sour cream, it's in the name, it's sour, gone bad, but nope, let's just give it a taste, cottage cheese, I don't know where cottage comes from but it's literally curdled.... let's just dig in and see what we got here... I'm sure most of this stuff was discovered during a famine."


"Oysters. That mother f'ker was hungry."


"20,000 years ago: 'Hey, maybe if you pry open this rock there will be something to eat inside.'"


"What did you find?"


"Cool I bet it goes with cocktail sauce"


"Soy sauce. It's a bunch of rotten soy bean juice with salt in it. Who tf thought that was a good idea to try."

I realize that school safety has been severely compromised and has been under dire scrutiny over the past decade and of course, it should be. And when I was a student, my safety was one of my greatest priorities but, some implemented rules under the guise of "safety" were and are... just plain ludicrous. Like who thinks up some of these ideas?

Redditor u/Animeking1108 wanted to discuss how the education system has ideas that sometimes are just more a pain in the butt than a daily enhancement... What was the dumbest rule your school enforced?

One of the golden rules of life? Doctors are merely human. They don't know everything and they make mistakes. That is why you always want to get another opinion. Things are constantly missed. That doesn't mean docs don't know what they're doing, they just aren't infallible. So make sure to ask questions, lots of them.

Redditor u/Gorgon_the_Dragon wanted to hear from doctors about why it is imperative we always get second and maybe third opinions by asking... Doctors of Reddit, what was the worse thing you've seen for a patient that another Doctor overlooked?

When we think about learning history, our first thought is usually sitting in our high school history class (or AP World History class if you're a nerd like me) being bored out of our minds. Unless again, you're a huge freaking nerd like me. But I think we all have the memory of the moment where we realized learning about history was kinda cool. And they usually start from one weird fact.

Here are a few examples of turning points in learning about history, straight from the keyboards of the people at AskReddit.
