Dr. Joy sits down with neuropsychologist Dr. Tanisha Hill-Jarrett, assistant professor at UCSF's Memory and Aging Center, to talk through what brain health means, why it's broader than mental health alone, and the daily habits that support it: cardiovascular exercise, a heart-healthy diet, stress management, social connection, and quality sleep.

They dig into what our phones are doing to us. Dr. Hill-Jarrett breaks down how short-form video triggers a bigger dopamine response than a typical reward, why the unpredictability of a feed keeps us scrolling, and what that means for sleep, attention span, and memory. She shares her own strategies, including separate personal and professional Instagram accounts and the Pomodoro method for resetting focus without reaching for a screen.

The conversation turns to her research on Black women and Alzheimer's disease. Black Americans face 1.5 to 2 times the risk of white Americans, and Black women carry the highest projected prevalence of any group, a gap that shows up even among women who are upwardly mobile, largely tied to the neighborhoods they live in. Dr. Hill-Jarrett also unpacks weathering, the term coined by Arlene Geronimus for the accelerated biological aging that Black women experience, and points to research showing Black women's telomeres suggest they are roughly seven and a half years biologically older than white women at the same age.

She closes with her current work on Afrofuturism and hopefulness, including a 10-week workshop where participants imagined a future free of time scarcity and reported feeling more hopeful about shaping what comes next. Her advice for anyone worried it's too late to protect their brain: it never is.
