Is Full-Time Work Bad For Our Brains?

You could be disappointed. If you're over 40, working more than 25 hours of work a week could be impairing your intelligence, according to a study released in February by researchers for the Melbourne Institute of Applied Economic and Social Research in Australia.
Working 25 hours a week (part time or three days a week) was the optimum amount of time spent working a week for cognitive functioning, while working less than that was detrimental to the agility of the brain for both men and women, the study found.
