Why is everyone quitting their tech jobs right now?
This image is from Mad Men and the iconic moment when Peggy rage quit her agency gig.
A little brief:
From the drama-infused Basecamp mass resignation to the quiet moments where someone decides to move onto a new job adventure, people are quitting a lot lately.
Without being too melodramatic, tech leadership has been letting people down for years.
People would rather quit their jobs and find someone else to work for than continue to work for a manager they no longer trust.
While the letdowns may have been happening for years, people quitting is due to optionality.
With the booming freelance economy and remote work, there's more opportunity than ever to make money, so people are feeling less tethered to their employers.
Now people are realizing that hustle culture is an unhealthy and unsustainable way to live your life and build a career.
Once "Being an office family" became code for having to put up with low pay and low-grade abuse just because there's catered lunch, people lost their appetites.

Hippocampus and Memory
via Thought Co
A little Brief:
The hippocampus is the part of the brain that is involved in forming, organizing, and storing memories.
The hippocampus is a horseshoe shaped structure, with an arching band of nerve fibers connecting the hippocampal structures in the left and right brain hemispheres.
The hippocampus is found in the brain's temporal lobes and acts as a memory indexer by sending memories out to the appropriate part of the cerebral hemisphere for long-term storage and retrieving them when necessary.
Ammon's horn is another name for the hippocampus major or hippocampus proper.
The hippocampus is important for converting short-term memories into long-term memories.
The hippocampus has been the focus of attention for the medical community as it relates to memory disorders such as Post Traumatic Stress Disorder, epilepsy, and Alzheimer's disease.
Prolonged emotional stress negatively impacts the hippocampus as stress causes the body to release cortisol, which can damage neurons of the hippocampus.
What Does Science Say About Flying and Fire Breathing Dragons?

A little brief:
A flying, fire-breathing reptile could never exist in real life, right? It's true no fire-breathing dragons have ever been discovered, yet flying lizard-like creatures exist in the fossil record.
Take a look at the science of winged flight and possible mechanisms by which a dragon might even breathe fire.
Scientists generally agree modern birds descended from flying dinosaurs, so there isn't any debate about whether dragons could fly.
While dragons of the past may have been large enough to carry off a sheep or human, modern dragons eat insects and sometimes birds and small mammals.
The family includes domesticated bearded dragons and Chinese water dragons and also the wild genus Draco.
You can find these living flying dragons in South Asia, where they are relatively common.
While European dragons are massive winged beasts, Asian dragons are more akin to snakes with legs.
Déjà Vu: The Science Behind the Eerie Feeling of Familiarity

A little Brief:
If you've ever had the feeling that a situation feels very familiar even though you know it shouldn't feel familiar at all, like if you're traveling in a city for the very first time, then you've probably experienced déjà vu.
Déjà vu, which means "Already seen" in French, combines objective unfamiliarity - that you know, based on ample evidence, that something shouldn't be familiar - with subjective familiarity - that feeling that it's familiar anyway.
According to a paper published in 2004, more than 50 surveys on déjà vu suggested that about two-thirds of individuals have experienced it at least once in their lifetime, with many reporting multiple experiences.
The single element familiarity hypothesis suggests you experience déjà vu if one element of the scene is familiar to you but you don't consciously recognize it because it's in a different setting, like if you see your barber out on the street.
Since you can't recall the other room, you experience déjà vu.
In one study, participants looked at rooms in virtual reality, then were asked how familiar a new room was and whether they felt they were experiencing déjà vu.
One researcher suggests that you experience déjà vu when the parahippocampal system, which helps identify something as familiar, randomly misfires and makes you think something is familiar when it shouldn't.
