Real-Life Spies

"TV shows and movies go out of their way to make military/intelligence officers look bada**."

"But real-life 'spies,' by design and training, are boring. They have regular houses and standard second-hand cars, they dress down, and they have vague, boring job titles (accounts receivable) as cover, and they do not draw attention to themselves. Most come from specialized academia."

The Sneakiness of Drowning

"When a drowning victim is revived, get them to a hospital as soon as possible. Drowning is the leading cause of death of kids from the age of one to seven and is ruled as accidental drowning when it comes to secondary drowning or dry drowning."

"Basically, your lungs are full of water despite being revived. Your lungs will absorb the liquid, but not before your body acidifies from high levels of carbon dioxide. The only chance to survive is to have the lungs pumped with oxygen via CPAP machine and time."

"Also, drowning is extremely quiet. You don’t hear the victim go under. And if you see flailing, do not attempt to save the victim otherwise you’ll become another drowning victim. Throw them a lifeline and hope their amygdala realizes that a rope or something is floating near them and grabs on it."

Not Everyone's Favorite Chocolate

"Hershey’s chocolate has the strong smell of vomit or feces to some people (me), and that’s because they use butyric acid as a preservative. Butyric acid is the compound that makes vomit smell so bad."

"Edit: Digging further into it, there are some claims that they may not be “adding” the butyric acid, but rather it is occurring from essentially spoiling the milk in their milk chocolate. Either way, the butyric acid and putrid smell remains a part of their product."

- hefewiseman1

"That explains the weird aftertaste I always get! I don’t smell it but their chocolate always has this super unpleasant sharp/acidic aftertaste that I find repulsive. I assume this is why!!"

Mapping Out the War

"Beginning in 1911 in anticipation of the outbreak of WW1 in 1914, two statesmen, one from England and one from France, began visiting locations in France that they believed would be the settings for a number of major battles that would occur during the great war."

"Long bike rides through these future battle zones in the countryside and weeks spent building a foundation for a French-Anglo codebook that would later prove important in helping win the war."

Avoiding Lawsuits > Protecting Patients

"Doctors, or surgeons more specifically, that make too many mistakes during surgery, ie, leaving instruments in patients, frequently gets ‘quietly traded’ to other hospitals where they continue their path of destruction with the patients not being aware of their past record. Hospitals tend to keep quiet about the matter to avoid lawsuits."
