Advances in ageing biology, multi-omics, artificial intelligence and preventive medicine are creating the possibility of a different model, one that identifies declining resilience earlier, targets shared drivers of age-related disease and preserves health across the course of life. But significant questions remain. Can healthspan be measured with sufficient scientific and clinical confidence? Which discoveries are ready to move beyond the laboratory? And can healthcare systems, regulators and investors build a credible pathway from promising science to interventions that improve meaningful human outcomes? This discussion will examine whether healthcare is ready to move from managing disease to protecting health—and what must change for that ambition to become a new standard of care.
