Challenging work that requires lots of analytical thinking,planning and other
managerial skills might help your brain stay sharp as you age,a study published Wednesday
in the journal Neurology suggests.
Researchers from the University of Leipzig in Germany gathered more than 1,000
retired workers who were over age 75 and assessed the volunteers'memory and thinking
skills through a battery of tests.Then,for eight years,the scientists asked the same group
to come back to the lab every 18 months to take the same sorts of tests.

Those who had held mentally stimulating ()demanding jobs before retirement
tended to do the best on the tests.And they tended to lose cognitive (function at a
much slower rate than those with the least mentally challenging jobs.The results held true
even after the scientists accounted for the participants'overall health status.
"This works just like physical exercise,"says Francisca Then,who led the study.

After a long day at work-sure,you will feel tired,but it can help your brain stay healthy.
It's not just corporate jobs,or even paid work that can help keep your brain fit.Then
points out.A waiter's job,for example,that requires multitasking,teamwork and decision-
making could be just as stimulating as any high-level office work.And "running a family
household requires high-level planning and coordinating(协调),”she says.“You have to

organize the activities of the children and take care of the bills and groceries."
Of course,our brains can decline as we grow older for lots of reasons-including other
environmental influences or genetic factors.Still,continuing to challenge yourself mentally
and keeping your mind busy can only help.
