The human body is a fascinatingly complex machine. Blood flows through our veins carrying oxygen and nutrients, our liver and kidneys remove waste from that blood, and electrical signals travel through our nervous system to make it all happen.

Some things about our bodies are a little less fascinating and a little more disturbing, though.



Take allergies, for example. Our immune system, which usually protects us from threats like bacteria, viruses, and parasites, can suddenly decide that a random thing we encountered is dangerous and trying to kill us.

That peanut butter you just accidentally touched: totally trying to kill you (at least, a person who is allergic to peanuts' immune system thinks it is).

It's not that the substance is actually harming the body, but the immune system recognizes it as a pathogen and tries to attack it. This can result in unpleasant symptoms like hives, diarrhea and vomiting, difficulty breathing, and even anaphylaxis.


So yeah, our bodies are fascinating and complex, but they're definitely far from perfect.

Reddit user u/RustyUnicorn wanted to know more about these odder things about the human body, so they asked:

"What's the most unsettling fact about our bodies?"

Be forewarned: some of these are a bit gross.

A brain aneurysm can happen at anytime, regardless of heatlth, that will cause instantaneous death. There are nearly no prior symptoms for detection. So you could just die at any moment in your life and there is nothing to warn you of it.

My professor called them "death's ninjas" and I can honestly never stop seeing them that way.

You can be making a sandwich, and bam, you're dead before you hit the ground.

The digestive tract extends from your mouth to your anus. In other words, you have a hole through you. You're a doughnut.

Grinding your teeth can put up to 900 lbs of pressure (psi) on your teeth (especially those who are night grinders). That’s like the pressure of 10 5th graders standing on your teeth. Please get a mouth guard if you grind your teeth at night. Save your teeth and your money. (Source: I'm a dental school student)

Some of your ligaments are so strong that they'll break your ankle before they get damaged themselves.

Happened to me. Broke my ankle - but what really happened is the ligament ripped a piece of bone off. Imagine attaching a toilet plunger to the wall - and then pulling on it so hard that a big chunk of wall just ripped right off. That’s what happened to my ankle.

You are less of a single animal and more of a super organism. The average human body has more bacteria than somatic cells. You are actually thousands of different organisms working together.

Next time you're feeling down, let this remind you just how incredible you are.

You're never alone! You've got a bunch of microscopic little buddies with you!

The sense of smell requires physically touching molecules (unlike audio/vision, which are waves).

That means that when you smell someone's fart, something that was inside their colon is now inside your nose. Little bits of their poop are inside of your head.

If the lining in stomach disappeared, you would digest yourself.

Cancer happens when a cell goes rogue and refuses to destroy itself on schedule. Then when it multiplies, the new cells don't destroy themselves either. Soon there's a massive tumor whose only crime was not wanting to die. Unfortunately, that s**t kills the whole body.

This is why cancer is so difficult to cure. It's not some foreign invader. It's your own cells just doing their own thing instead of functioning as a unit.

There are things rotting and decaying inside you right now. Some of those things are, in fact, You.

Life is hard. It's a miracle to make it through with some semblance of sanity. We are all plagued by grief and trauma. More and more people of all backgrounds are opening up about personal trauma and its origins. Finally! For far too long we've been too silent on this topic. And with so many people unable to afford mental health care, the outcomes can be damaging.

All of our childhoods have ups and downs and memories that can play out like nightmares. We carry that, or it follows us and the first step in recovery is talking about it. So who feels strong enough to speak?

Redditor u/nthn_thms wanted to see who was willing to share about things they'd probably rather forget, by asking:

What's the most traumatizing thing you experienced as a child?

Being single can be fun. In fact, in this time of COVID, being single can save lives. But the heart is a fickle creature.

And being alone can really suck in times of turmoil. None of us are perfect and it feels like that's all anyone is looking for... perfect.

Now that doesn't mean that all of us are making it difficult to partner up. Sure, some people are too picky and mean-spirited, but some of the rest of us are crazy and too much to handle. So one has to be sure.

The truth is, being single is confusing, no matter how much we try to match. So let's try to understand...

Redditor u/Mcxyn wanted to discuss some truths about love and our own issues, by asking:

Why are you single?

Whether you're an at home parent, a college student just leaving the nest, or a Food Network junkie, there are a few basic tips that everyone should know.

Chef's gave us some of their top tips for amateurs and beginner at home cooks that will really make a difference. They are trained professionals with years of experience in the kitchen, so they definitely know what we're all missing.

If you're looking to improve some of your cooking skills and techniques, but you're still learning how to boil water correctly, this list is for you.

Redditor BigBadWolf44 wanted in on the secrets and asked:

"Chefs of Reddit, what's one rule of cooking amateurs need to know?"

Let's learn from the masters!


What a common mistake!

"A lot of the time when people add salt to a dish because they think it tastes flat, what it really needs is an acid like lemon juice or vinegar."

- Vexvertigo

"Instructions unclear I drugged my dinner party guests and now they're high on acid."

- itsyoboi_human

"Yes! Or tomatoes. They're pretty acidic too and go with so many things. Our dinners are so much better once the garden tomatoes are ripe. Or if a dish is too acidic, oil/butter or a little sugar can help add balance to it."

- darkhorse85

"Like tomato and eggs. Every Chinese mom makes those slightly differently and I haven't had a tomato egg dish I didn't like yet."

- random314

"There's a book called 'Salt Fat Acid Heat' that comes highly recommended to amateur cooks."

- Osolemia

"Reading even just the first chapter about salt made a lot of food I cooked immediately better, because I finally understood salt wasn't just that thing that sat on the dinner table that you applied after the meal was cooked."

- VaultBoy42

"Salt is important for sweets. A batch of cookies without that little hint of salt doesn't taste quite right."

- Osolemia

Unfortunately, this tip might not be accessible to everyone. Many people who contracted COVID can no longer use their sense of smell the way they used to.

"Have a friend that lost his smell from COVID, and now he only recognizes if food is salty, sweet, sour or bitter."

- AlphaLaufert99

"Just wait until he gets his sense of smell back and a ton of foods smell like ammonia or literal garbage now. Yeah, that's fun... It's been 7 months for f*cks sake just let me enjoy peanut butter again!!!!!!!!!"

- MirzaAbdullahKhan

You can't take back what you've already put in.

"You can always add, but you cannot take away."

- El_Duende666

"I find people's problems usually are they're too scared to add rather than they add too much."

- FreeReflection25

"I see you also grew up white in the mid-west."

- Snatch_Pastry

Safety first!

"Not really a cooking tip, but a law of the kitchen: A falling knife has no handle."

- wooddog

"I'm always so proud of my reflexes for not kicking in when I fumble a knife."

"If I drop anything else, my stupid hands are all over themselves trying to catch it (and often failing). But with a knife the hardwired automatic reaction is jump back immediately. Fingers out of the way, feet out of the way, everything out of the way. Good lookin out, cerebellum!"

- sonyka

"Speaking of KICKING in. On first full time cooking job I had a knife spin and fall off the counter. My (stupid) reflex was to put my foot under it like a damn hacky sack to keep it from hitting the ground. Went through the shoe, somehow between my toes, into the sole somehow without cutting me. Lessons learned: (1) let it fall; (2) never set a knife down close to the edge or with the handle sticking out; (3) hacky sack is not nearly as cool as it could be."

- AdjNounNumbers

"Similarly, NEVER put out a grease or oil fire with water. Smother with a lid or dump baking soda in there (do not use flour, as it can combust in the air making things worse)."

- Metallic_Substance

How else will you know it tastes good?

"Taste the food."

- OAKRAIDER64

"Also don't be afraid to poke and prod at it. I feel like people think the process is sacred and you can't shape/flip/feel/touch things while you cook them. The more you are hands on, the more control you have."

"No, this does not include situations where you are trying to sear something. Ever try flipping a chicken thigh early? That's how you rip a chunk out of it and leave it glued to the pan until it's burnt."

- Kryzm

Here's one just for laughs.

"When you grab a pair of tongs, click them a few times to make sure they are tongs."

- Kolshdaddy

"People really overlook this one. You've gotta tong the tongs a minimum of 3 times to make sure they tong, or else it can ruin the whole dish."

- BigTimeBobbyB

If you're looking to get into cooking or to improve you technique, pay attention to these few tips.

Salt generously, add an acid to brighten things up, and don't forget to taste your food!

If all else fails, you can always order take out.

As part of the learning process, children often do embarrassing things before they learn a little more about the world and all the different implications therein. While the inappropriate moment is usually minor and ends in laugher some instances are truly mortifying.

One such instance involved a little sister who was around 6 at the time. It was the 90s and at the height of the youth-focused PSAs (think the frying egg representing your brain). One type was a safety PSA about stranger danger. The speaker would remind the children that if a stranger tried to take you anywhere to yell “Stop, you're not my mommy/daddy" to raise the alarm.
