Is Exercise Really Medicine? An Evolutionary Perspective by Daniel E. Lieberman

Full paper: Conclusion: “The bottom line is that just as cultural innovations are causing the physical activity epidemic new cultural measures are needed to restore the need to move in our environments. Until we do so effectively we can expect to remain trapped in a pernicious vicious circle in which by treating the symptoms rather than the causes of diseases that are caused by physical inactivity we will permit the exercise paradox to persist and worsen.” ;
