Complex jobs could help keep brains sharp in later life
Having a career as a lawyer, architect or engineer may help a person stay a better thinker as they age. So concludes a study by researchers at Heriot-Watt University in Edinburgh, Scotland.
Previous research has suggested that complex jobs can help sustain a higher level of cognitive thinking later in life, but the Scottish teams was able to take into account the childhood IQs of the more than 1,000 people they analyzed. Even with taking IQs into consideration, the researchers found that the people they had categorized into a complex jobs group tended to perform better on cognitive tests they took in their 70s. Educational and criminal backgrounds and access to services were also factored in.
According to the study, working in a high thinking job had roughly the same benefit as not smoking on cognition in later life.
The research was published in the journal Neurology.
