The human body is one of the most fascinating things on Planet Earth. Paradoxically, it’s at once extremely fragile and tougher than you think, adapting very quickly, and designed to bounce back even after serious injuries. Some people move beyond what most of us think our bodies are capable of doing, setting new athletic achievements—David Goggins alone has shown that people can endure far more than they give themselves credit for.
However, it isn’t all gold medals and victory parties. There are some truly disturbing and even creepy things about the human body that would sound like science fiction if we didn’t know better. Folks from the r/AskReddit online community shared the weirdest facts about human biology they know, and we’re sharing the most interesting ones with you.
Scroll down if you want to learn something new. Hopefully, you’ll still be able to sleep at night knowing some of these. Got any unusual facts about our bodies to share with all the other Pandas? We’ll be waiting to read all about it in the comment section.
Bored Panda reached out to health and fitness coach Anna Armagno Toussaint to have a chat about how much exercise and movement people should strive to get every day, as well as what people's biggest diet mistakes are. (Spoiler warning: many of us are eating an excessive amount of sugar.) We also got in touch with the author of the thread, redditor u/BathNo7713, to get their perspective as well. You'll find Anna and the redditor's answers to our questions below.

Being ignored or rejected has the same effect on the brain as a physical injury. Repeated rejection overtime causes other mental and physical health probkems like depression and ptsd. We never forget the feeling of being rejected or ignored and when recalling the memory you feel the emotional pain again. When we try recall physical pain, our brains do not allow it happen. You know you had pain at the time but the memory doesn't cause the pain again.

As a former civil engineer, it always shocked me how close the waste disposal and recreation areas were placed to each other.

Adolescence. Most mammals hit adulthood in one clean break. Our kids hit a terrifying state of not being able to take care of themselves but capable of and hormonally hell-bent on reproducing. Like, what kind of messed-up series of horrors made THAT a biological advantage?

Fibrodysplasia ossificans progressiva is a disease that is undetectable, and the cause is not known. It appears when your muscle cells start being replaced with bone cells. Eventually, over year, your body locks up until you're entirely "locked in" and you suffocate.

A few weeks ago I had emergency surgery because I was severely bleeding out internally. The source was a ruptured ovarian cyst. Worst pain of my life. I don’t have PCOS or any reproductive condition and the doctors informed me that everyone with a uterus has existing cysts. It’s a matter of tough f****n luck that one of mine tried to kill me but it could happen to anyone.

People with pancreatic cancer can have a “sense of impending doom” weeks to months before being diagnosed.
Edit: sorry for adding to your anxieties! If you aren’t a middle aged or older smoker, you shouldn’t worry too much about this. If you are…please stop smoking. There are drugs and behavioral therapies that can help you quit. I love you.
Edit 2: as others have pointed out, there are other diseases that have this symptom too. You can freak out about this fact or just take the moral of the story: if you feel like something is wrong, don’t wait (hesitation is defeat). Set up an appointment with your doctor, ask them what it could be and how they’re going to determine what it is. Ask questions and take care of yourself.

That the placebo effect is way stronger than most people think. In Vsauce's video on the subject, a kid suffering from constant seizures stopped having the seizures, I'm pretty sure entirely. And all because they put him in a machine that they said "healed him" when in reality it did nothing.

Most of the bacteria that will decompose you when you die is already inside you and makes up a sizeable portion of your body mass. That’s why removing organs staves off decomposition of a body for longer.

Our brains create false memories way more often than we think. False memories occur pretty easily as well. Going along with that, the more "vivid" a memory seems the more likely it is that it's fabricated. On top of that, the more we recall a memory, the more susceptible to change it becomes and then the modifications that have been made seem more real because us recalling and then consolidating it further cements it in our memory to be "true".
A fun fact to go along with all this information is that deja vu is actually your brain spontaneously fabricating a new false memory and that's a perfect example that showcases the vividness we experience in our false memories.
