"I prefer clean water for everyone, over champagne for a few people." Oligarchies are so passé. You are fools. And you are being laughed at by organized, intelligent human beings who simply aim to be free.

He's gonna be a new man. (He's surrounded by an energy bubble of love right now.) One of these days, when the world wakes up to what this procedure is conceptually, we as a medical/scientific community will make it less invasive. I am sure of it. These first patients, including dear Charles, are LEGENDS for signing up. A true BRAVE MARINE. @POTUS You need to know about this treatment.

@Fynnderella1 @Kevin_McKernan It's a calming mechanism of the brain signaling safety. I didn't read that anywhere - it's just common sense. When there's a predator around, the birds scatter. Alert mode: activated!

Your brain has a circuit that doesn't know you live in a city. Its only job is to monitor whether birds are still singing. Right now, in this room, it is on. The circuit predates primates. Mammals have been using ambient soundscape continuity as a predator-detection system for roughly 200 million years. Birds stop singing when something larger moves through their territory. For most of mammalian history, a forest full of song meant no large predator was nearby, and the cessation of sound was the warning. Your nervous system never updated this software. The Max Planck Institute tested the inverse in 2022 with 295 participants. Six minutes of birdsong dropped anxiety with a medium effect size. Six minutes of traffic noise raised depression with the same. The effect worked on subjects who lived in dense urban environments and had no regular contact with nature. The brain still ran the check. Birdsong sits in the 1,000 to 8,000 Hz range. Your brainstem reads continuous patterns in that band as a signal that nothing dangerous is currently moving through the environment. EEG data shows birdsong at 45 to 50 decibels boosts alpha wave activity by 14.1% relative to silence. Alpha is the brainwave signature of relaxed alertness. Push the same birdsong above 60 decibels and the response flips. Stress markers rise 29%. The circuit only trusts the signal at the volume of quiet conversation, which is exactly the volume birds sing at from a typical distance. Three things happen simultaneously when the brain registers ambient safety. The amygdala downregulates. The parasympathetic nervous system takes over from the sympathetic. Heart rate variability rises, cortisol drops. The posterior cingulate cortex, which sits at the center of the rumination circuit, quiets down. King's College London tracked this through a smartphone study with over 1,200 participants and found the mood lift lasted hours after the sound stopped. People diagnosed with depression got the same response as healthy controls. Most of what gets labeled mental fatigue is hypervigilance running in the background. Birdsong tells the circuit it can stand down, and the brain reallocates the freed compute everywhere else. A quiet park feels different from a quiet office because the parks have sentinels.

I have come to a point in this life where when I hear someone even to elude to a non-existence of free will, then I know they are "working for the wrong team" - whether transiently in a state of total forgetfulness or intentionally to deceive others. @harari_yuval I am open to speak with you on this subject matter having expressed my opinion here, since you have expressed yours. @rustyrockets You are welcome to join - if this debate happens - since you've met Yuval and (from my vantage point) saw a light in him. I think he's in the former category.
