Figure 1. From longer life span to longer health span (and life span). From A to B: Standard medicine increases lifespan by preventing death from age-related diseases. It simultaneously increases a number of old people suffering from age-related diseases. A ratio healthspan to lifespan is decreased. From B to C: Anti-aging intervention will slow down aging and delay the onset of age-related diseases. This in theory will restore a ratio of healthspan to lifespan.
