- Fentanyl delivery methods were compared: 72-hour transdermal patches vs. six-month implants; implants were argued to reduce abuse potential, daily sourcing burden, and social visibility.  
- A tongue-in-cheek “green” argument was floated that fentanyl’s microgram-level potency lowers per-dose carbon footprint versus milligram-scale drugs, though synthesis and supply-chain emissions were noted as the real determinants.  
- Extensive literature review on selegiline (deprenyl) was shared: early rodent/dog/fly studies showed lifespan extension; additional findings include neuroprotection against anticholinergics, modest slowing of early dementia, protection of dopaminergic neurons from unknown CSF toxins, cardioprotection in rabbits with heart failure, and modulation of cytokine biosynthesis.  
- A link to a Journal of Immunology paper on thymic regeneration via androgen blockade was posted, highlighting the trade-off between immune investment and reproductive resource allocation across the lifespan.  
- A novel tempeh preparation was proposed—steam-cooking instead of boiling soybeans to retain phytonutrients—followed by discussion of the practical hurdles (contract manufacturing, food-safety certification, shelf-space competition, cold-chain logistics) for launching a niche functional-food startup.
