Longevity & biological age: complete guide
Living longer is one thing. Living longer in a healthy body is another. The signals your wearable already captures (VO2max, biological age proxies, cardiac fitness, health pattern detection) turn out to be among the strongest predictors of healthspan in long-term studies. This page collects the articles on each.
