Humans have a seemingly ceaseless appetite for “fun facts” but one brave, intrepid netizen, perhaps in a moment of boredom, posted “I’m sick of fun facts. Give me your worst not-so-fun fact. Make me regret asking,” and so people did just that.

If you finish this list and, well, regret it, don’t say you weren’t warned. Otherwise, get comfortable as you scroll through, upvote your favorites and be sure to share your own examples in the comments down below.

A microscopic view of a disturbing mite, a fact that changes the way people see the world. Everyone has demodex mites living on their faces and in their eyelashes! It’s up to you if you want to google what they look like under a microscope, but suffice it to say, they are not cute.

    And even getting diagnosed is a nightmare! Try getting a doctor (male or female) to take you seriously. "They're meant to hurt". Oh, am I supposed to be completely useless for 2-3 days and then in "normal" amounts of pain for 3-4 more days? And I know that others get it much worse

    A quokka, a small marsupial, standing on a tree stump. Disturbing facts changed the way people see the world. The animal often associated with throwing its baby at predators is the quokka, but they don't actually throw them; instead, the mother releases the joey from her pouch to distract the predator, allowing the mother to escape, a harsh survival tactic also seen in kangaroos and wallabies. This instinctive behavior, sometimes called "infant abandonment," prioritizes the mother's survival so she can reproduce again

    At least someone does something against unnecessary waste! Go rabbits! Serious: My brother and I had two as kids (Klopfer and Blume) and the breeder we got them from explained this behaviour, but I forgot. It was a very good reason, but it depended somehow on the kind of p**p.

    An animal skull lies on dry, cracked desert ground, revealing disturbing facts. Every organism that has ever lived has either died or will die.

    The universe is expanding, and distant galaxies are already moving away from us faster than light, making them permanently unreachable.

    Earth has undergone at least five mass extinction events, none of which were preventable by the dominant species at the time.

    Not-so-fun fact: we don't need honey bees that much for pollination. They can actually be harmful for native species, both to flora and insects. For example, a chilean plant called "chilco" gets its flower ripped when a honey bee enters it to feed. The plant can't pollinate and the native pollinators starve.

    The biggest natural (not human-related) k*llers of Australia’s Koalas and Tasmanian Devils are awful diseases:

    In Koalas it’s Chlamydia, a s*xually transmitted disease which causes urethritis, cystitis, reproductive disease, blindness & death.

    In Tasmanian Devils it’s Devil Facial Tumour Disease, a contagious cancer which spreads when infected Devils bite each other. It causes large facial tumours that interfere with feeding, leading to organ failure, starvation, infection, & death.

    Male giraffes when they want to mate with a female will gently nudge or kick the female giraffe to essentially ask them to pee. If the female is willing she will pee after this. The male will then drink it to see if the pheromones that are there when the female is ovulating are present before mating with them. This behaviour is called a flehmen response.

    Cleanliness testing is wiping out the horseshoe crab population.
    Horseshoe crab blood is legendary for its sensitivity to endotoxin, a type of toxin produced by Gram-negative bacteria such as E. coli. Because of this, horseshoe crab blood is harvested from the animals and used in all sorts of LAL/endotoxin testing. This is essential in both the pharmaceutical and medical device industries. Problem is, many horseshoe crabs don't survive the blood harvesting process. It's devastating!

    When homeless people age into dementia, they are no longer able to attend to any self-care at all. So when they are eventually brought into hospital, they often have toenails that have grown through their footwear, and the skin on their feet builds up inside socks or shoes and forms a moist, pungent goop that blends the fabric of socks with skin. They need their feet soaked carefully to remove the socks without tearing the skin. Often there are wounds that have ulcerated and bled into the goop.
