Can We Really Extend Human Life? What Helps Now & What’s Next | Kira Labs

Can we extend human life—or help people stay healthier for longer? In the first episode of Kira Labs: Now & Next, I explore what helps today, what scientists are testing, and what would count as convincing evidence of life extension. Explore Kira Labs: https://kiralabs.org/ Research and Healthspan Lab: https://kiralabs.org/research.html I’m Robert McMurrer, founder of Kira Labs. This episode looks at healthy aging, exercise and mobility, the hallmarks of aging, senescent “zombie” cells, senolytics, PCC1, partial epigenetic reprogramming, biological-age clocks, and early human research. The central question is not just whether a treatment changes a laboratory measurement. What does it mean for someone’s health, independence, and years of life? We also introduce Healthspan Lab, my research software project for organizing scientific papers and clinical-trial information while keeping different types of evidence separate. Which topic should we explore next: memory, muscle, senescent cells, or cellular reprogramming?
