Your Complicated Job Might Keep Your Brain Young

Your job could be protecting your aging brain. Scientists at the University of Edinburgh found the more complicated someone's job is, the more likely they are to score well on memory and cognitive thinking tests into old age.
The researchers first looked at the childhood IQ tests of around 1,000 elderly participants. They then compared those results with cognitive testing done when the participants were 70 — years after retirement for some.
Researchers defined the complexity of a job by using definitions from the Dictionary of Occupational Titles and scored jobs on level of complexity. They divided jobs into two types: jobs that require you to work with people, and those that require you to work with data.
