Quantifying the Reduction in Mortality Risk that Accompanies Physical Fitness

It is well established that physical fitness (and the level of activity and other lifestyle choices required to sustain it) correlate with a lower risk of mortality and longer life expectancy. Human data largely cannot provide evidence for causation, but that greater activity and fitness slow aging and extend life is robustly demonstrated in animal studies. Many large epidemiological studies have quantified the reduction in mortality risk provid…
