Challenging work tasks sharpen brain

London: If your job requires more speaking, developing strategies, conflict resolution and managerial tasks, you may be better protected against memory and thinking decline in old age than your co-workers, says a study."Our study is important because it suggests that the type of work you do throughout your career may have even more significance on your brain health than your education does," said study author Francisca Then from University of Leipzig in Germany. "Education is a well-known factor that influences dementia risk," Then noted.
