An international consortium of longevity researchers introduces a multi-factor 'usable organ capacity' model that emphasizes optimizing individual organ function through lifestyle interventions and personalized assessments, contrasting with broad statistical life expectancy benchmarks to enhance both healthspan and longevity.

Key points

• Quantified organ capacity via metrics including biological potential, maximal functional capacity, decline rates, and stress-induced fluctuations.
• Integrated multi-factor model combines genetic, environmental, and lifestyle data to tailor personalized longevity strategies.
• Predictive lifespan modeling contrasts organ capacity trajectories against critical dysfunction thresholds to optimize healthspan and lifespan.

Why it matters: This personalized organ-centric longevity paradigm shifts away from statistical averages, unlocking targeted interventions that more effectively extend healthspan and lifespan.
