The Thing About Crows

"Crows are the smartest species of bird with the intelligence of a human 7 year old. They can make lever tools to solve complex problems, use currency, visit their grandparents, and can remember a face for at least 5 years and can mimic sounds they hear."

"They can also pass the snack test: a test where you offer them a small portion of food with the promise of a larger portion if they decline it. Human toddlers and most primates can't pass this test. They're also self-aware."

"Crows are so smart that they'll take something like a walnut, drop it on a busy street for a car to run over it, and then wait for a red light to pick up the seeds. They're also capable of using strategy like simple attack formations flanking and decoys. If a random crow is found dead, the remaining murder of crows will actually split up and find clues that led to that crow dying and try to avenge them."

"Probably the only reason why they haven't waged war on humanity is their ongoing blood feud with owls. Owls are known for stealing their hatchlings and crows have passed on their hatred of owls for multiple generations."

"They hate owls so much that if one is found alone, a murder of crows will go out of their way to show that owl why they earned the name for a group of them. Zoos can't even keep owls and crows in the same aviary without an all-out battle breaking out.

"If you save an owl from a murder of crows, they'll remember your face and pass their hatred of you across multiple generations and across multiple murders in the area. Expect to see sh*t all over your car, bundles of sticks on your windshield and beak marks on your hood wherever you go for multiple city blocks."

A Different Deck

"There are more combinations of a deck of cards than there are particles in the entire Earth. Not just molecules or even atoms, individual protons, electrons, etc. To put it bluntly, you can safely bet that when you shuffle a deck of cards that combination of cards has never been created before ever or ever will be."

Everything has an expiration date. That would include our planet. But rest assured, we're over 2 billion years away from the sun engulfing mother earth.

But can we just stop at the earth's life expectancy? I can't even begin to imagine how long a million years is, let alone two billion when all the world's oceans are all dried up and making our world uninhabitable.

Don't worry though, we'll all have departed long before then. As to what will contribute to the demise of the human race, who knows? I shudder to think about it.
