People with mentally challenging jobs, like air traffic controllers, doctors and financial analysts, tend to stay mentally sharper. Study lead author Gwenith Fisher at [b]Colorado State University[/b] said: 'Working in a job that involves a lot of thinking, analysing, problem solving, creativity and other complex mental processing is related to higher levels of cognitive functioning not only while we are still working but after retirement as well.' This is not to suggest a link between mental demands on the job and workers' mental function.
