From Aleteia:
Many grandparents delight in doting on their grandchildren — from bedtime stories to bundled-up walks in the park. But according to a new report, there may be a deeper benefit to that loving involvement than just warm memories.
A study reported by Tony Dokoupil for CBS News suggests that grandparents who actively help care for their grandkids tend to perform better on memory and language tests and show slower cognitive decline over time than those who do not. So simply staying engaged with the life of a child, the research by the American Psychological Association suggests, may help keep aging minds more responsive and resilient.
