Study shows being a little more fit than couch potatoes gives large benefit to longevity.
New research has underscored the surprising importance of being a "little more fit". In this study 4384 healthy people were divided into five levels of fitness. This research focused only on the differences between the least fit (Q1) and the next level of fitness (Q2). Amazingly, those in Q2 demonstrated almost half the mortality of those in Q1. Being even a little more fit was associated with a big jump in longevity. While overall activity levels didn't vary much during the subjects adult lives, recent activity did. This recent physical activity seemed to offer the benefit.
