Approximately 75% of women ki**led by their ab**ers are m**dered when they try to leave or after they have left the relationship. This makes leaving an abusive relationship a particularly dangerous time for women. The most dangerous time for a woman in an a**sive relationship is when she attempts to leave or has just left. And people are still going on with the “if it was so bad why didn’t she just leave??” Bulls**t!

We are most likely past the point of no return with climate change and every year will get hotter and hotter as more permafrost melts releasing millenia old greenhouse gasses and more and more forests burn releasing the carbon they had captured in their lifetime.
We are in “silver bullet” territory.

Prion diseases exist.
mro_running:
Should’ve kept at as “read in comments.” I decided to google it and wish I hadn’t.
canceriandog:
Prion diseases occur when proteins normally in the body misfold and trigger a cascade of misfolding proteins which result in illness. We don’t know why this happens and there is no way to predict it. There is no cure and all prion diseases are universally fatal.

Parrots express their love for you by regurgitating food for you like they would for a mate that was stuck nesting or for a young baby. Every pet owner that has ever been truly loved by a parrot has been intentionally barfed on…we just don’t talk about it…

Idk, the older I get the more I’m horrified by this simple truth: It doesn’t have to be this way.
Humans (if only a few whom have hoarded wealth and power amongst themselves) have chosen to make the world the way it is.
It doesn’t have to be this way.

The smell of fresh cut grass is actually a distress signal to alert others plants of potential danger. So everytime you enjoy the smell of cut grass, you’re enjoying the sweet smell of suffering.

Tarantula hawk wasps have a unique breeding method that caused Darwin to have a crisis of faith and question the existence of a benevolent god! They inject a tarantula with a paralytic and drag it off to their burrow where they proceed to lay their eggs inside of the still alive tarantula. When the little parasites are born they proceed to eat the still living tarantula from the inside out, making sure to avoid any vitals until finally the tarantula mercifully dies and they burst out of the husk.

Basically, our bodies constantly vibrate when we move, causing pain in about every joint there is. Our nervous system is designed to totally ignore those micropains. Unfortunately, elderly people experience increasingly more of such pains due to deterioration of the body. Imagine if all of us could feel all of this pain 24/7.

Our bodies are a ship of Theseus. Over the course of seven years, every cell in our bodies dies and falls off or is excreted. At the same time, new cells replace the old ones as they die. Thus, every seven years we get an entirely new body, and the body you were born in is actually long gone.

There are about 100,000 human bodies buried under Washington Square Park in New York City.
When the park was being escalated, they found out the land leased to the city to build it on had once been a potter’s field. Since the city had no away to identify the bodies buried there, and due to the logistics and expenses of moving a hundred thousand bodies, they opted to simply leave the bodies interred and build the park over them.

We probably don’t have the materials to get to where we are today again.
The easy to obtain coal, oil and metals that got us to today have been largely depleted to get us to today.
To extract what’s left, it’d take considerable resources even for our modern society.
If we mess this up, there’s no getting back to this point.

Here’s a few
1.The air in your house is probably more polluted than outside. You very likely have mold spores around your house that do more harm than outside.
2.Blow dryers in bathroom blow faces particles onto your hands. This is because when you poop, or even fart, the same is just fecal partials floating into your nose, and since they float around, they end up on and in the dryer.
3.Sometimes when it’s silent, your brain makes noises, which is why sometimes you hear things or even your name.
