challenges, but new research from the University of New South Wales

shows the upshot may be a bigger hippocampus, the part of the brain

responsible for learning and memory. Being a manager potentially may

ward off common neurodegenerative diseases, such as Alzheimer's. The

research is thought-provoking for policymakers as they attempt to keep

mature individuals in the workforce longer to tackle the dilemmas of an

ageing population. And senior staff may want to think again about the

prospect of early retirement.
