"Use it or lose it" has dominated thinking on how to protect the aging brain, and extensive research shows there are many benefits to remaining physically and mentally active as people get older.

"The completely shocking and puzzling thing about this new paper is . . . [brain activity] is what you think of as keeping you cognitively normal. There's the idea that you want to keep your brain active in later life," said Michael McConnell, a neuroscientist at the Lieber Institute for Brain Development, who was not involved in the study. "The thing that is super unexpected is . . . limiting neural activity is a good thing in healthy aging. It's very counterintuitive."
