• A call was made for a concise, non-commercial “personal longevity roadmap” that synthesizes the best evidence-based interventions; in response, Eli outlined a hierarchy of sleep, diet, exercise, blood/genomic testing, and low-risk supplementation (creatine, magnesium, potassium, vitamin D) while pointing to Peter Attia’s book “Outlive” as a science-focused starting point.

• Eli emphasized VO₂ max and grip strength as powerful, measurable predictors of lifespan and suggested that lowering resting heart rate—an easy proxy for metabolic rate—may confer longevity benefits, echoing the cross-species observation that total lifetime heartbeats are roughly constant.

• Discussion turned to scar-remodeling therapy: robertmcdougal_73197 is attempting to source the peptide GsMTx-4 (a Piezo-channel blocker) to inject into existing surgical scars for 6–12 months, citing mouse data showing reduced hypertrophic scarring and a mechanistic rationale involving ECM stiffness, mechanotransduction (FAK/Rho/ROCK/mTOR/YAP), and positive-feedback fibrotic gene expression.

• Supporting literature shared includes the Nature paper “GsMTx-4 reduces hypertrophic scar formation” (https://www.nature.com/articles/s41419-021-03481-6) and a 2023 study on Piezo inhibition reversing established scars (https://pubmed.ncbi.nlm.nih.gov/37066136/).

• The evolutionary justification for mammalian scarring—rapid wound closure to prevent infection in the absence of sterile care—was contrasted with emerging regeneration strategies such as Morphoceuticals’ bioelectric-state resetting approach for human limb regeneration.

• Microneedling was briefly surveyed as both a cosmetic procedure and a dissolvable-patch delivery system for mRNA therapeutics, with a Yale Medicine explainer link provided (https://www.yalemedicine.org/conditions/microneedling).

• Yamanaka-factor–based age-reversal work was raised as potentially relevant to scar remodeling, given reports that partial reprogramming simultaneously reduces senescence and heals fibrotic tissue.

• geneh2 criticized the Future of Life Institute’s newly revealed $665 million crypto-funded AI-safety war chest, linking to a Politico article on the controversy (https://www.politico.com/news/2024/03/25/a-665m-crypto-war-chest-roils-ai-safety-fight-00148621).
