When deeply focused — such as watching a compelling movie — blink rate can drop to as low as 2 per minute, showing focus and relaxation are entirely different states.

Blink rate is one of the most reliable physiological signals available in everyday conversation. Stress drives it from the normal 15 per minute up to 85–90. Intense focus drives it down to 2. Psychopaths in interviews who don't blink aren't relaxed — they're intensely focused. Use blink rate as a real-time gauge of engagement or stress in any conversation.
Average human blink rate in conversation is about 15 per minute; under stress it can spike to 85–90 without the person noticing, making it one of the most reliable behavioral stress indicators.
Men communicate best when shoulder-to-shoulder doing something with their hands — not sitting face-to-face. Old West bars put up mirrors so men could talk side-by-side while still seeing each other's faces, which reduced bar fights. The Australian Men's Sheds initiative doubled men's willingness to discuss mental health simply by giving them a task to do while talking.
Animals first sensed light 540 million years ago, triggering an evolutionary acceleration known as the Cambrian explosion within 10 million years.
It is estimated that half of all cortical activity in the human brain is involved in visual function, underscoring vision's central role in intelligence.
Cognitive neuroscience literature shows that by age 6, humans can recognize tens of thousands of different object categories — far more data than early AI systems were trained on.
Only about 3% of FDA-approved drugs have genuinely unclear mechanisms of action, making an unknown mechanism a meaningful early red flag for any compound.
Even compounds that clear preclinical testing often fail in humans: 30 to 50% of drugs entering phase 1 trials do not advance to phase 2, frequently because human behavior differs from animal models.
More than 80% of published BPC-157 research comes from a single academic group whose researchers have IP and commercial interests connected to the molecule, limiting independent replication.
Roughly 100 peptide drugs are already FDA-approved, about 150 more are in clinical trials, and 600–700 are in preclinical development, underscoring the legitimacy of peptide science broadly.
The scientist who discovered BPC-157 refused to disclose the screening method used to identify the compound and has never fully published the parent protein sequence — what Peter Attia calls 'scientific trust me, bro.'
The brain's visual, auditory, and motor cortices light up nearly identically whether an experience is real or imagined, making visualization a form of actual neural training.
