Based on everything we know about the brain’s plasticity, it makes logical sense that people with jobs that challenge them mentally would be likely to stay sharp as they age. Now, a new study from the University of Edinburgh has found that it’s likely to be true, and posit that having a mentally challenging job may protect the aging brain.
The study examined a subset of people who had been involved in previous research, and who had been tested as children across a variety of intelligence measures in 1947. They found that the people who had jobs that were cognitively challenging (involving complex work operations) maintained better cognitive health than people who had other types of jobs. Examples of cognitively challenging jobs included careers in medicine, science, engineering, and the arts.
