In a new paper published by the Center For Retirement Research, analysts examined an array of jobs and whether they require “fluid intelligence,” or “crystalized intelligence.” Jobs requiring the acquisition of lots of new information may be harder for older workers to continue. However, occupations that rely on accumulated knowledge and perfected skills may be easier to continue beyond the traditional retirement age. How does your job rate in their assessment?
