The exact neurovascular cascade behind why your vision blacks out when you stand up too fast and why you don't actually pass out. 👇
• The Gravity Drop: When you are lying down, your heart pumps blood easily on a flat plane. The moment you stand up abruptly, gravity instantly pulls about 500 to 800 mL of your blood straight down into your legs.
• The Transient Drain: This sudden pooling means less blood returns to your heart, which temporarily means less blood is pumped up to your head. For a split second, your brain experiences a drop in pressure.
• The Visual Blackout: The retina (the back of your eye) is incredibly sensitive to oxygen and pressure changes. When the blood pressure dips, the retina temporarily shuts down to conserve energy which is exactly why your vision goes black or static.
• The Baroreceptor Rescue: Luckily, you have pressure sensors (baroreceptors) in your neck. Within milliseconds, they detect the blood pressure drop and fire a panic signal to your brainstem.
• The Sympathetic Snap: Your autonomic nervous system instantly kicks in. It violently constricts the blood vessels in your legs and spikes your heart rate, physically squeezing the blood right back up to your brain. Vision restored.

🚨 BOMBSHELL:
Hillary Clinton & Huma Abedin allegedly caught harvesting & drinking Adrenochrome on video.
Found on Anthony Weiner’s laptop inside a folder labeled “insurance.”
An investigator was asked about “Frazzledrip”… his response is absolutely mind-blowing 🤯
Will this ever see the light of day?

@gerardcneuro@XRPcryptowolf It's not a loss until you sell.
Crypto is a long-game... the world hasn't even adopted it en-masse yet. We are EARLY.
People are so emotional.... it's exhausting to see people panic. Take a step back and realize we are at the start of an explosion on a global scale.
Just remembered the world sauna championship. Was one of the most interesting things I've read about
It used to be hosted in Finland every year until the incident in 2010. Rules were that it started at 110°C (230F). Then 1 litre of water was poured onto the stove every 2 minutes
The last person to walk out under their own power won
In 2010, both finalists had to be dragged out
The russian finalist died, burned all over, and the reigning Finnish champ went into a coma and woke up 6 weeks later with 70% of his skin burned, kidney failure and his airways completely roasted
One peculiar thing about it was there were no prizes. Only in one particular year did the winner get 1 small prize, some special heat resistant speakers that could be used in a sauna
But despite this, participants went to the edge of death every year and would do insane stuff like grow their hair out long specifically to cover their ears so it didn't get burned by the boiling water vapor
It was interesting to me because it's another piece of evidence that as soon as you create a ruleset... no matter how ridiculous it is, no matter how small the group of participants, no matter the extremely chance of death, and no matter a total lack of prizes. There will always be men willing to compete to the point of actually killing themselves
The male brain enters a kind of hypnotic trance where it will completely convince itself of the worthwhileness of the task, so long as it begins to venture seriously down the path of a competitive interest
It's kind of like a hijacking of the programming evolutionary mind, where no incentive makes sense but it happens anyway. You can find a million examples of this for every male interest on the planet. Just the simple act starting down a path confers it meaning to the person, and the more they are surrounded by other men who care about the same thing, the more they learn and compete, the more entranced by it they are, until their identity is fully subsumed by it and stuff like these sauna deaths happen
Seeing lots of things like this taught me to be very careful when I start down the path of any competitive interest or business, because getting hypnotized by what you are doing is essentially guaranteed. So it's good to assume it'll happen and be totally sure the outcome is worth your potential self-destruction
This is why it's still cold at night in June! Time IS NOT REAL.
We are not our ages.
We are ritualistically aging ourselves with birthdays counting fake time.
Our seasons are thrown off.
The birds are out at night chirping like it's sunrise.
The sunflowers aren't facing the sun because the real sun is no longer in use.
This new sun replaced the old one with the old "time."
The slower time.
Time, how we remembered it before, with the yellow sun.
