I'm saying this without even a hint of sarcasm: learning new things is so cool. There are so many wild fun facts about the world that blow my mind on a regular basis. However, there are insane facts that are the exact opposite of fun.

These are some of the most disturbing and terrifying not-fun facts we found.

After a person dies, the chemical adenosine triphosphate, which provides the energy to cells, depletes and lactate builds up in the muscles.

This process causes the muscles to stiffen, triggering rigor mortis and causing the arrector pili muscles to stiffen, giving rise to goosebumps.

People who handle cockroaches develop allergies to them. This usually prevents them from drinking pre-ground coffee because of the cockroaches that sometimes get ground in with the large batches of beans.

Deep-sea octopus eggs take over five years to hatch. During that time, the mama octopus never leaves the "nest" to feed (meaning she doesn't eat for five years!). She normally dies when the babies finally hatch.

Tapeworms can grow to be up to 32 feet long inside of your body, and they eat half of what you eat. In fact, some people have even tried to ingest tapeworms to help with weight loss.

Fatal familial insomnia exists. It's a rare, incurable prionic brain disease that progressively destroys your brain’s ability to sleep. Eventually, you stop sleeping altogether, go insane, have seizures, and die.

Whales don't die of old age so much as they eventually just don’t have enough strength to resurface to breathe. Instead, they slowly drown while swimming because they can't get new oxygen.

In 2014, the CDC found a smallpox sample that they had lost without even realizing it. It was just lying around in some random storeroom at an unsecured government lab outside Washington, D.C. The smallpox virus was initially declared eradicated from the world in 1980.

When your skin becomes red from spending too much time under the sunlight, it's basically because your skin cells are committing suicide to avoid becoming cancerous. That's why sunburns turn into dead skin that just peels off.

Your lips are made of the same skin type and texture as your anus, which objectively makes sense based on the structure of the digestive system. However, I still hate this information.

Touching an AM radio broadcast tower will not only kill you, it will also hurt the entire time you're dying since your body gets incorporated into the electric current. Weirdly, you'd be able to hear whatever was on that particular station as you die.

Brushtail possums are coprophagic (they eat their own poop). They need their food to go through their digestive system twice to get all the nutrients.

ADVERTISEMENT

They're nocturnal, so they spend the night eating eucalyptus and other plant leaves and flowers. During the day, they curl up into a little ball with their mouths close to their bums and eat their poop as it comes out in. While they're out the next night, they poop again.

Unborn babies grow a mustache in the womb, which then spreads to cover the entire body. The baby then eats the entire hair, called lanugo, and excretes it after birth with their first bowel movement, which is a substance called meconium.

As dead bodies undergo the process of decaying, they "burp," or release gasses. It's for this reason that caskets and mausoleums need to be ventilated so that the gas can escape.

It's predicted that there are 50 active serial killers at any given time in the US. Many serial killers fly under the radar because police information isn't often shared effectively across jurisdictions; for example, it's believed that the Zodiac Killer could've been caught 50 years ago if not for this issue.

South Koreans have a superstition called "fan-death," where if you keep a fan on too long it will kill you. The term's origin is much darker.

In the past, when people committed suicide and the coroner had to determine the cause of death, they would say it was "death by fan" to save the face of the family and not cause them shame.

Fossilization is actually quite rare. It takes a very specific set of circumstances for something to even become a fossil, let alone have it survive to the modern day, meaning there are likely millions of species of animals, plants, and other organisms that we will never know about.

Suicide bombers are a lot easier to identify post-mortem than you'd expect. This is because the blast from the suicide belt hits the base of the head in such a way that the head pops off like a cork. Investigators, therefore, have a relatively intact head to ID.
