@GovTimWalz How do you sleep at night knowing that you turned Floyd into a martyr. A man on a path of destruction was given not only a pass but also turned into a twisted hero. Have you no conscience??? How on earth was this a win for you?
@TulsiGabbard Thank you for your service and passion for your country! We appreciate you and are grateful for your contributions. We pray for you to be blessed and we lift up your husband to the Lord for healing. 🇺🇸❤️
@MidwesternDoc@VigilantFox Have you had any success with treating NAION? My current understanding is that there is nothing can help once those blood vessels have been affected.
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.
@ScottAdamsSays Thank you for sharing your journey and wisdom Scott, you have enriched the lives of so many! May the peace of Jesus be with you as you make the most important decision of your life. “He who believes in me shall have everlasting life”. -Jesus
@ScottAdamsSays@joelpollak Thank you for your contributions Scott. I have enjoyed your depth of thought as well as your humor. Praying God gives you as much time as you need. Peace be with you always.
@MikhailaFuller Thanks for the update, we lift your dad and family up to God for complete healing. We cherish and are grateful for his contributions to the world and we pray he has the strength to continue sharing his deep insight and, shining his brilliant light in the darkness.
@joeroganhq@elonmusk He loves this country and is gifted in so many ways, I highly recommend the book, “Elon”, the insight it provides into his process is unique to say the least. It offers a window into his approach for streamlining and cost cutting.
