## Resource

The future of medicine lies in a proactive 'health stack' designed to prevent chronic disease rather than just treating it. Alex Karnal explores how GLP-1s and PCSK9 inhibitors are shifting the paradigm from reactive care to long-term biological optimization.

## Highlights
- Main idea: The 'health stack' approach focuses on preventing the three primary killers—cardiovascular, neurocognitive, and inflammatory diseases—through early intervention
- Practical takeaway: GLP-1 medicines serve as the first commercial proof that patients are willing to adopt proactive, preventative pharmaceutical strategies
- Failure mode: Cancer remains the most difficult challenge because its ability to mutate and redirect pathways can render effective treatments obsolete
- Technological shift: The next frontier of drug discovery requires agentic, robotically-driven systems to overcome the throughput limits of human-led experimentation
- Investment insight: High-quality diagnostics must be evaluated based on both sensitivity and specificity to enable effective early-stage intervention
