History of individual trajectories and strategies to expand the ; Performance against age in arbitrary units for (A) an individual that alters his in a self autonomous manner and (B) effect of a beneficial strategy on another individual . The described in (A) is the result of perturbations associated with (i) detrimental lifestyle (such as sedentary behavior) in early childhood, (ii) an injury or disease affecting the performance and (iii) a major change in lifestyle that results in an artificial, delayed age of peak performance occurring much later in life. In (B) we show how a beneficial strategy is expected to expand the , providing room for an increase in performance
