Bacteria and viruses can be frozen for millions of years and still be viably infectious, and having never encountered humanity before, could have no end of catastrophic results should they be uncovered and manage to infect a person or animal. Not to worry though, it’s not like millions of ancient pathogens are currently trapped in permafrost which is now melting bit by bit each and every day...

There are more creatures in your mouth than there are people on earth

One reason why crows and ravens are associated with death is because they would often follow armies as they marched into battle. Being both carrion birds and extremely intelligent, they realized that a large group of armed men marching in one direction meant that there would be a tasty meal of corpses to eat soon afterward.

It wasn't until 1987 that the American Academy of Pediatrics declared it unethical to operate on newborns without anesthesia. Until surprisingly recently, the medical community felt it would be dangerous to give infants anesthesia and/or believed that they didn't feel pain.

The bottom of Lake Superior is cold enough that the bodies of dead sailors just...remain. They don't really decompose because it's at freezing temperatures, so they instead get a coating of adipocere, which is liquid body fat, hardened around them.

If you get a blood transfusion and get the wrong type of blood, one of the symptoms is 'a sense of impending doom.'

The smell of a freshly cut lawn is actually a chemical distress signal released from the grass as it's cut. You're smelling the souls and screaming of the innocent.

Rosemary Kennedy was JFK’s sister. She suffered from oxygen deprivation at birth and that unfortunately stunted her mental growth. She had a pretty decent childhood, but as she grew older she began to act out. Afraid that her behavior would risk his political career, her father, Joseph, agreed to have her lobotomized. Her mother, Rose, was against it and forbade him from doing it. So he did it behind her back when she went on a trip. After the operation, Rosemary’s already low IQ was lowered even further, to the point she could no longer walk or communicate. Her family had her locked up in an institution and basically disowned her. They never visited and never publicly acknowledged her anymore. Rosemary died at the age of 86. Her mother never for gave her husband for what he had done.

Female mummies in Ancient Egypt were always more decomposed than their male counterparts. They discovered that this was because male bodies were embalmed a lot sooner than female bodies. Female bodies were kept at the family home until they started to decompose in order to avoid necrophilia at the embalmers.

Crocodiles can gallop like horses. I don't like knowing this so I am cursing you people with this knowledge as well. Fortunately, alligators cannot.

There is a genetic disease called fibrodisplaysia ossificans progresiva. When tissue is damaged, it is replaced with bone. Growths form underneath their skin and their joints lock solid So over time those affected slowly become encased in a prison of bone just beneath their own skin. They usually have to choose between sitting or standing up for the rest of their life. By the end of their life they have to drink every meal through a straw and can barely move

Blobfish in its natural habitat looks like a normal fish, but it lives so deep under water that it doesn't use a normal gas bladder to keep itself balanced. Instead, it has a spongy skin that is slightly less dense than water, which becomes damaged and bloated when fishermen bring it up too quickly. It's not really the ugliest fish. It has just experienced something worse than one of us being thrown into outer space. Between sea level and space, there's one atmospheric pressure of difference. Between sea level and 2000 feet under water, their upper limit, there's 60 atmospheres of difference.

Mount Everest is covered in frozen corpses because removing them is very unsafe and time consuming. They are easily viewed from the climbing routes and some are used as trail markers.

If the sun exploded right now, you would be blissfully unaware of it for just over eight minutes while the energy travels at the speed of light to get to you.

Cockroaches have been recorded eating human flesh, both living and dead, as well as fingernails, eyelashes, feet, and hands. The American cockroach and German cockroach are more likely to bite humans than other species. Pretty sure Australian cockroaches do something equally creepy, but as an Australian who plans to sleep at some point in the future, I'm not going to google it.

The Colombian serial killer Pedro Alonso Lopez, who is known as the Monster of the Andes, raped and murdered over 300 girls from Ecuador, Peru and Colombia. However, after he was caught and imprisoned for 18 years, he was put in a psychiatric hospital. There he was reviewed, declared to be sane and was set free, in spite of his blatant avowal that he fully intends to kill again. Since he was released in 1998, nobody knows where he is or what he’s doing. ( He is supposed to be 71 years old at present).He is known for being the most prolific killer ever.

If you stifle a sneeze there’s a chance you can damage organs in your head, including eye blood vessels, rupturing your eardrums, and possibly rupture a brain aneurysm. Which means there’s a small chance stifling a sneeze can kill you. Better to be the loud ass with the sneeze that can be heard around the world than a dead loud ass cause someone told you to stifle that sneeze

It’s quite common after you die to burp a lot as you have more gas build up. Dead bodies can also sit up on their own sometimes

There’s a parasite that enters a fish’s mouth, eats the tongue and replaces itself as the fish’s new tongue

There are upwards of 300 active serial killers in the world

Your brain can play tricks on you to make you see monsters in the mirror. This is called the Troxler Effect. It's an optical illusion that affects how you perceive things, both visually and mentally.

Eventually there will be more dead people on Facebook than alive. Wow thanks for the award.

Either somebody knows where Malaysia flight 370 went missing to, or nobody does. Both are equally terrifying.

The astronauts aboard the space shuttle Challenger most likely didn’t die until they hit the water miles below the initial explosion.

When you happen to be murdered there is only an about 40% chance that your murderer will be found and punished.

1 in 100 people are psychopaths.

Your eyes have a separate immune system from the rest of your body. If they get damaged in such a way that it affects anything other than your eyes, your regular immune system can attack the damage and will not recognise them, meaning your own body can permanently blind you. What's worse, your body cannot tell the difference between either eye. If one of them gets infected or damaged, your immune system can attack your healthy eye and take away your sight entirely.

There's a spider that gives you an hours-long, very painful boner before you die from its bite.

Serial Killer Richard Chase took any unlocked door as an invitation to come inside.

CNN has had a pre-recorded broadcast from the 90’s which they will premiere during the end of the world

Tarantulas can swim.

Ducks become cannibals due to boredom , of all reasons. They can only be stopped by cutting off their "mouths"!

A single tiger has killed over 436 people in India.

Every year you live through the future anniversary of your death.

Since 1900, over 13,000 people have been murdered by serial killers in the USA.

The stonefish, an incredibly venomous fish living in tropical waters mostly off the coast of Australia and parts of US, can cause pain that only escalates with time. Eventually the pain will subside but even after the barb is removed, patients have reported increasing pain 12+ hours later. Without antivenim or denaturing the venom with excessive heat, the pain builds and builds until the patients request euthanasia. Its spines hold the venom, hidden in its dorsal fins. Aboriginals living around the Great Barrier reef have "corroborees," large gatherings, and will during these gatherings hold reenactments of people being stung by this monster (for what I assume is either amusement, learning, or both).

A black mamba is the fastest snake which can slither at a speed of 12.5 miles an hour (20km/hr). They have neurotoxins which are fast acting. The venom shuts down the nervous system and paralyses the victim. Its venom is able to kill 10 people and it repeatedly bites. To add onto this, there is an almost 100% kill rate and can kill in 20 minutes.

After getting stung by a cone snail, you don’t feel the sting for a little bit. There is no antivenin and it can be lethal. Treatment is basically keeping the victim alive until the venom wears off.
