with @DrSaraMargolin: How Inevitable is Dementia?

Dr. Fran sits down with Dr. Sarah Margolin — cognitive scientist, associate professor, and creator behind @DrSarahMargolin — to talk about what the science of aging actually says, and why so much of what circulates online gets it wrong.

Dr. Margolin studies cognitive aging and reading comprehension, and she's built a following by taking on viral myths about getting older — from the false idea that "aging is a disease" to the assumption that memory lapses always signal dementia. In this conversation, she breaks down:

• The real difference between normal age-related forgetfulness and dementia, including what a basic cognitive screening (like the MMSE) actually tests for
• Why the biopsychosocial model — nutrition, exercise, mental engagement, and social connection — matters more than any single supplement, peptide, or "hack"
• What the Mediterranean diet really means
• How mindset around aging and menopause can measurably affect symptoms, and why cross-cultural research shows attitude matters
• Why older adults are more tech-capable than we give them credit for
• What it's like to design and run a research study from the ground up, and why "doing your own research" is a lot more rigorous than reading a headline

The two also get into the broader mission behind Dr. Margolin's In Plain Science series — an effort to demystify how research funding, peer review, and scientific ethics actually work, so people can better evaluate the claims they see online.
