@Cash_Nicholson@Babygravy9 If you really wanted to make a statement, the boss move was obvious:
Take on the challenge. Read the single Harry Potter page. Donate the $750,000 to dyslexia charities. Use the moment to bring awareness to the millions of people who struggle with dyslexia every day.
“Everything ugly weakens and afflicts man. It recalls decay, danger, impotence; he actually suffers a loss of energy in its presence. The effect of the ugly can be measured with a dynamometer. Whenever man feels in any way depressed, he senses the proximity of something ‘ugly’. His feeling of power, his will to power, his courage, his pride - they decline with the ugly, they increase with the beautiful.”
- Friedrich Nietzsche
First mushroom trip data is out: my brain activity.
Dose: 5 g dried Psilocybe cubensis (B+ strain)
Containing 24.9 mg psilocybin
Psilocybin longevity experiment.
What we see in the brain:
+ brain activity data mirror my subjective experience
+ strong decrease in my brain’s control center (prefrontal + premotor cortex)
+ strong increase in sensory, auditory and speech integration
+ higher entropic brain patterns: open, flexible, less predictable, exploratory
+ brain network patterns resembling a youthful state vs aged and rigid
Matching what I reported experiencing:
+ “felt like my consciousness was dialed up to 10/10.”
+ “I felt hyper aware and hyper alive.”
+ “I experienced sense of touch with awe.”
+ “my mind was insatiably curious and wanted to deploy its sensors into the world and discover all things.”
+ “My brain wanted to stare, study and marvel.”
+ “The flavor exploded in my mouth.”
+ “...restored my perception to youthful levels, returning them to factory settings and dissolving my aged numbness.”
Why this could matter for longevity:
+ In people aged 65-85, higher happiness was linked to a 22% reduced risk of all-cause mortality over 15 years.
+ A meta-analysis showed that optimism correlated with a 35% decrease in heart attacks and a 16% decrease in all-cause mortality.
+ Having a strong purpose in life is associated with a 17% reduction in both heart attacks and all-cause mortality.
+ In psychedelic medicine, treating depression with ketamine has been shown to reverse biological age by up to 3 years.
Together, these findings suggest a plausible mechanism by which psychedelics, including psilocybin, can prolong both health and lifespan by improving mental well-being and rewiring the brain to a more positive, creative, and curious state.
My team and I hypothesized that neuroplasticity, the loosening of rigid inhibitory patterns that makes the brain more flexible, creative, and relaxed, and even the subjective psychedelic state itself may be as meaningful for longevity as methylation shifts, senescence reversal, or telomere biology.
What’s happening mechanistically
Earlier work shows that psilocin (the active metabolite of psilocybin) acts primarily as an agonist at 5-HT₂A serotonin receptors in the cortex. These receptors are especially dense in high-level association and sensory regions, as mapped in a high-resolution PET/MRI atlas of the human serotonin system.
When these receptors are activated, brain imaging studies show an induced state of desynchronization, entropy, and neuroplasticity. This process erodes the rigid brain hierarchy and default mode networks in favor of a brain-wide spontaneous, creative, curious, and child-like state.
Kernel Flow data shows the same pattern:
The recorded timepoints included:
+ baseline: directly before session start (not shown)
+ timepoint 1: 4 hrs after dose (acute phase effects).
+ timepoint 2: end of the day, before bedtime.
+ timepoint 3: the following morning.
I continue to measure my brain daily.
Image notes
+ The three maps show changes vs. baseline (not absolute activity)
+ Red = increased connectivity, blue = decreased connectivity vs. my baseline.
+ The left reference map shows the 5-HT₂A receptor distribution from PET, the main psilocybin target.
Time Point 1 - 3 hrs post dose
+ Reduced connectivity in the prefrontal and premotor cortex, correlating with acute brain desynchronization.
+ Increased connectivity and hyperintegration between the primary motor and sensory cortex regions.
+ Enhanced connectivity in the auditory and speech areas of the cortex.
+ Inhibited connectivity in the medial prefrontal and posterior zones, areas associated with the Default Mode Network (DMN).
Subjective experience:
+ Enhanced sensory vividness and bodily presence: The brain's top-down hierarchy, originating in the pre-frontal cortex, was attenuated. This reduced predictive filtering, leading to a flood of bottom-up sensory information and heightened bodily perception (e.g., a fascination with water and light dynamics in a jar, a restored, primal joy of touch and sensation).
+ Peak neuroplasticity and cortical entropy: A peak in cortical entropy and neuroplasticity contributed to a feeling of hyperawareness (e.g., heightened sensory perception, feeling "at one with existence," hyper-aware and hyper-alive).
+ Deeper appreciation of music and uninhibited movement and expression: Sharpened auditory senses and reduced top-down inhibition allowed music to be enjoyed on a profound level. Concomitant functional connectivity in speech-motor and auditory-motor integration areas facilitated uninhibited expression through both speech and movement (a restored, uninhibited, child-like joy of music).
+ Note: Full ego dissolution was not experienced, which may necessitate a higher dose to achieve more advanced desynchronization of the prefrontal and parietal cortices.
Time point 2 - 5 hrs post dose, end of trip
+ Intensified sensory and motor hyperconnectivity.
+ Continued increased connectivity in auditory and speech centers, with a relative restoration of connectivity to the speech understanding area.
+ Partial re-emergence of the prefrontal parietal coupling, while prefrontal context remains partially inhibited.
+ Partial re-emergence of connectivity in areas related to the default mode network.
Subjective Experience
+ High-order brain networks begin to restabilize, alongside persisting sensory, motor, auditory, and speech hyperconnectivity, suggesting neuroplasticity in action.
+ The narrative shifts from pure sensation and experience to meaning generation, accompanied by deep philosophical reflection (e.g., reconsidering the meaning of life and one's relationship with mortality in the time of AI, and pondering the future of human evolution).
Time point 3 - next morning (afterglow)
+ Persistence: Patterns from the acute phase continue, including general prefrontal cortex inhibition, ongoing neuronal plasticity, and heightened senses.
+ Intensified connectivity: Increased connectivity is noted in the speech generation area and the somatic sensory association area.
+ DMN inhibition: The default mode network remains inhibited.
Subjective Experience:
+ "Afterglow" effect: Characterized by continued sharpened senses, calm clarity, emotional openness, and low inhibitions. For instance, I felt more comfortable expressing uninhibited, self-deprecating humor (i.e. my post making fun of myself about the insane lengths I go for my Don’t Die experiment)
+ Integration of experience learnings: The heightened activity in the somatic sensory association area aligns with the process of integrating and "making sense" of the raw sensory experience of both the self and the external world.
+ Enhanced creativity: The intensified connectivity in the speech generation area contributed to the uninhibited bout of creative writing I undertook to report my experience.
SCIENTISTS JUST PROVED YOU CAN REVERSE YOUR BRAIN AGE IN 4 HOURS
What happened on November 2025 will rewrite human longevity.
A single 25mg dose of psilocybin didn’t just alter consciousness. It physically rewound the human brain to a youthful state. Measurable. Reproducible. Persistent.
The data that changes everything:
Your brain’s default mode network … the rigid autopilot running your thoughts … collapsed by 40%. Entropy spiked 25%. Neural patterns identical to a child’s brain emerged within hours. The flexibility lasted days.
This isn’t theory. This is measurement.
Nature published it. Bryan Johnson documented it live. fMRI scans confirmed what sounds impossible: temporary brain rejuvenation through a single molecule.
Now connect the dots that will stop your heart:
Fifteen-year studies tracking 70,000 humans prove happiness reduces death risk by 22%. Optimism cuts heart attacks by 35%. Purpose and well-being … the exact states psilocybin produces … predict mortality better than cholesterol.
Ketamine already reversed biological age by 3 years on epigenetic clocks. Published 2025. Peer-reviewed. Repeatable.
Do the math:
One supervised session. Four-hour brain state shift. Four-week plasticity window. One to three years of biological age erased. Sixteen to thirty-five percent lower death risk through sustained well-being.
For one billion aging humans, this means 300 billion prevented deaths. Three trillion dollars in healthcare saved. Ten to twenty percent extension of functional lifespan.
The mechanism is brutal in its simplicity:
5-HT2A receptors flood. Prefrontal rigidity dissolves. Sensory integration explodes. Your brain remembers how to be young. The entropy peak forces neural rewiring. The afterglow cements new patterns.
Phase 3 trials launch in 90 days.
If entropy doesn’t rise above 10% or lifespan gains fall below 5%, the hypothesis dies. If inflammation hits 20%, we stop immediately.
But if it holds?
Aging just became optional.
The compressed timeline between proof and protocol is 18 months. The distinction between medicine and evolution collapses.
One molecule. Four hours. Everything changes.
This is the inflection point.

@bryan_johnson you inspire me mate!
I might have to try shrooms (for science).
A psychedelic mushroom molecule just showed signs of slowing aging.
Psilocybin, the ingredient in magic mushrooms that alters your mind, slowed the aging process in human cells and extended lifespan in mice.
Here’s what the study found…
Bayer is a pharma company
Monsanto is a pesticide company
Bayer bought Monsanto
Bayer makes drugs for NonHodgkin's lymphoma
Monsanto makes a toxic herbicide called glyphosate to spray on food crops
Glyphosate causes NonHodgkin's lymphoma
