Three recent studies from the the National Bureau of Economic Research describe recent trends among older workers remaining in or retiring from the labor force and where their health status may fit in their decision to retire or not. A study from Germany estimated that two thirds of the workforce could continue work until age 70 based on projected health capacity and ability to work. Three additional studies from the Netherlands, Spain and Sweden find that workers possess healthy work capacity to extend their working careers past current retirement ages. A fifth study from Japan finds that these same estimates hold with an added emphasis on the importance of education to extended work capacity.
