Caring for the young may delay ageing in the brain.
Gro Amdam, who studies ageing in bees at Arizona
State University, observed improvements in
cognition among older bees that turn their attention
back to nursing. ---- Amdam’s theory is that when
older individuals participate in tasks typically
handled by a younger generation – whether in a hive
or in our own society – antioxidant levels increase in
the brain, which slows the ageing process.
