There’s a biological reason why we can’t resist puppy dog eyes. Sustained eye contact significantly raises oxytocin levels in both humans and dogs, which encourages love, trust, and bonding. This response isn’t even found in hand- raised wolves, which suggests humans and dogs may have co-evolved to share this trait in order to be companions. Source Source 2 Source 3

George Washington braved the dangers of war, had horses shot out from under him, and ventured into enemy territory during battle to return a lost dog to its owner - but no one ever claimed to witness him being the least bit nervous until he stood before Congress on April 30, 1789, and gave his inaugural address as the first President of the United States. Source

Senator William Maclay of Pennsylvania observed that ‘even the great Washington trembled when he faced the assembled representatives and senators:’ “This great man was agitated and embarrassed, more than ever he was by the levelled Cannon or pointed Musket.”

The first line of Washington’s First Inaugural Address, April 30 1789: “Among the vicissitudes incident to life, no event could have filled me with greater anxieties than that of which the notification was transmitted by your order, and received on the fourteenth day of the present month.”

There’s a dating app that prevents you from swiping right too soon. Appetence forces you to take things slow by making you talk to a match before you can see what they look like. Both profile images are blocked out by a pattern that slowly disappears when you ‘like’ each other’s messages. Your match has to like 50 of your messages to see your full photo, and you have to like 50 to see theirs. Source Source 2

Paris syndrome is a mental disorder experienced mostly by Japanese tourists who are disappointed when they visit the city for the first time. The shock of Paris not living up to their expectations can cause depression, sweating, anxiety, dizziness, hallucinations and delusions of persecution. The Japanese Embassy in Paris has a 24-hour hotline for those needing help, and up to 20 tourists a year are hospitalized. The usual treatment for Paris syndrome is ‘to go home.’ Source Source 2 Source 3

Pirates didn’t make their captives walk the plank. Though big fans of torture methods like flogging and marooning, there are no actual records of pirates using a plank. The first mention of plank walking was in a 1724 fictional novel by author Daniel Defoe, but if real-life pirates wanted to drown someone, they probably just threw them off the boat.

Egyptian pharaohs were often fat. Despite their slim and striking depictions in ancient artworks, they had sedentary lives and high-sugar diets that contained lots of bread, honey, beer, and wine. Examinations of various royal mummies show that many of them suffered from obesity, heart disease, and diabetes. Source Source 2 Source 3

No One Dies Alone (NODA) is a program in the US where volunteers keep watch over those who are dying. When hospital patients who have no one to visit them are in the process of passing away, the volunteers keep vigil at their bedsides by holding their hand, talking to them, or just being present to ensure they won’t be alone in their final moments.

did-you-kno:

Fallstreak holes are natural phenomena that often get mistaken for UFOs. These ‘hole punch clouds’ occur when water droplets inside a cloud freeze and fall beneath it, creating a large gap that looks like a perfect hiding place for a flying saucer.

Aliens, obvi.

The rarity of fallstreak holes is what tends to throw people.

That paired with the tendency to look at anything in the sky and cry ‘UFO!’ is the perfect makings of a false alien alarm.

Sometimes these clouds have little rainbows inside.

They aren’t always circular, though…

They make all kinds of crazy shapes.

Including airplane/sword/cross/wieners.

According to his biographer, 24-year-old Abraham Lincoln had to settle a financial dispute by betting a gambler he could lift a barrel of whiskey off the floor and hold it while taking a ‘drink out of the bunghole.’ If he lost, the gambler got a fur hat; if he won, the gambler got nothing. So Abe dropped to a squat, lifted the barrel to his mouth, performed a reverse keg-stand, and won the bet. Source

Lyndon Johnson’s secret service agents were also his personal relay team of traveling bartenders. They often trailed him in a station wagon while he drove his convertible around and drank scotch out of a big foam cup. Periodically, he would slow down, hang his arm out of the car, and shake his cup- then an agent would jump out, grab the cup, hand it off to an agent inside the wagon, wait for a refill, and run it back to LBJ, whose arm was still outstretched and waiting.

We don’t have any real pictures of the Milky Way galaxy. Most non-illustrated images of the entire Milky Way spiral are actually of another spiral galaxy called Messier 74. It’s impossible to take a full photo of the Milky Way’s spiral structure because it’s about 100,000 light-years across, and we’re stuck on the inside. Source  Source 2  Source 3

This is about as good as we can get:

This picture of the Milky Way was captured by NASA’s COBE satellite. This photograph was taken using the infrared spectrum, which allows astronomers to peer through the gas and dust that normally obscures the center of the Milky Way.

The United States officially adopted the metric system in the 1970s. Americans were supposed to start using it after the Metric Conversion Act was signed into law by President Gerald Ford in 1975- but it wasn’t mandatory for the general public, so most people didn’t bother.

Anxiety affects your balance. People with severe anxiety can also have balance problems, like feeling dizzy for no reason or swaying more than others when standing. Both issues begin at an early age, but, while it’s often difficult to treat anxiety in children, studies show treating their balance problems can help lower anxiety and boost their self-esteem.
