Is your second language secretly saving your brain? Dr. Samantha Yammine joins to explain new research suggesting multilingualism could be a buffer against aging — even if you're not fluent.

From overgrown neural “trails” to why we mimic accents, this episode explores how language affects cognition and brain health. Sam breaks down what the data actually shows, why correlation isn't causation, and how curiosity, not fluency, might be the secret ingredient. They also dig into the science of brain “cleaning,” how sleep ties in, and what we still don’t know.

This isn’t just trivia — it’s a compelling look at how daily habits shape our future brain health.
