Why do some people stay mentally sharp as they age while others experience a much steeper decline?

Dr. Tommy Wood studies brain health, cognitive performance, and the factors that help the brain remain adaptable throughout life. His message is surprisingly hopeful: the aging brain can continue to respond—but only if we keep giving it reasons to.

In this conversation, we explore what actually helps preserve cognitive function as we get older, including:

• Why the brain needs stimulation and challenge at every age
• How exercise supports brain health
• Why learning new skills and entering unfamiliar environments matter
• The role of social connection in cognitive aging
• Why the brain lets go of abilities we stop using
• How strength, movement, sleep, and nutrition contribute to long-term brain health
• Why avoiding all difficulty may be exactly the wrong strategy as we age

Tommy’s larger idea is simple: if you want your brain to remain capable decades from now, keep asking it to adapt today.
