Sixty-two-year-old Rocket50 founder Marie Jerusalem has never felt more able to adapt to the changing demands of the corporate world. “My body’s not as agile as it used to be, but mentally I’m stronger today than I’ve probably ever been in my entire career,” she tells Fortune.?

Americans are increasingly working past retirement age either because they want to stay engaged or because it’s impossible not to. Regardless, they all have one thing in common: They want to stay mentally sharp.?

Experts say these daily habits can help with that.

The basics

“Sleep disturbances have been associated with cognitive impairment and decreased physical function,” says Marie-Pierre St-Onge, PhD, director of the CUIMC Center of Excellence for Sleep & Circadian Research.?

Exercise also helps reduce sleep problems like insomnia.

A friendly neighbor

Having coffee with a colleague, volunteering in your community, or hosting a family dinner will help keep the brain stimulated.?

“Social activity protects against a variety of negative health outcomes in older age, including cognitive decline, dementia, and even early mortality,” says Patricia Boyle, PhD, a neuropsychologist with the Rush Alzheimer’s Disease Center in Chicago.?
