Dave breaks down how Bartonella slips past standard testing, why it's almost never on a conventional doctor's radar, and the specific PCR protocol you need to actually find it.  Sources:  https://pubmed.ncbi.nlm.nih.gov/     *High Tyrosine Levels May Be Cutting Years Off Men's Lives  A Mendelian randomization study of 270,000 UK Biobank participants found that elevated tyrosine is causally linked to nearly a full year of lost lifespan in men — with zero effect in women. The culprit appears to be an inflammatory oxidation pathway that men metabolize very differently. Dave examines what this means for every guy stacking L-tyrosine nootropics or eating high-protein keto.  Sources:  https://pubmed.ncbi.nlm.nih.gov/41045493/   https://www.aging-us.com/news-room/high-tyrosine-levels-linked-to-shorter-lifespan-in-men   https://www.usnews.com/news/health-news/articles/2026-02-27/study-suggests-one-common-amino-acid-may-affect-how-long-men-live     *Blue Light Blocking Contact Lenses Are a Legitimate Vision Upgrade  ALTIUS Vision's tinted contact lenses aren't just blue light filters — they cut chromatic aberration by 53% and improve motion tracking and contrast sensitivity in ways that software filters simply can't replicate. Dave covers the mechanism, who benefits most (screen workers, TBI recovery, gamers), and how to find a provider.  Sources:&…","meta_description":"This week's stories: *Bartonella Hides in Cat Scratches — and It Might Be Why You Feel Like Garbage A stealth bacterial infection transmitted…","key_points":[],"chapters":[],"topics":[],"duration_seconds":587,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/the-human-upgrade-biohacking-for-longevity-performance-1031629/episodes/superhuman-contact-lenses-motivation-supplement-stack-cat-scratches-cause-brain-fog-amino-acid-shortening-lifespan-and-more-1448/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/the-human-upgrade-biohacking-for-longevity-performance-1031629/superhuman-contact-lenses-motivation-supplement-stack-cat-scratches-cause-brain-fog-amino-acid-shortening-lifespan-and-more-1448.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
