Most women don't find out they're in perimenopause the way the books describe it. @CynthiaThurlow found out in Morocco — on her 15th anniversary trip — when her immune system quietly revealed that something had already shifted.
In this clip, Cynthia shares the story behind her new book The Menopause Gut, and Dr. Stephanie and Cynthia unpack something that doesn't get talked about nearly enough: how a declining hormonal environment makes women significantly more vulnerable to infections, immune disruption, and opportunistic illness — long before the "classic" perimenopause symptoms arrive.
They also get honest about why so many women resist the word perimenopause altogether, and what it actually costs us to stay in denial.
If you've ever thought "I'm too young for this" or "it's probably just stress" — this one's for you.

![Your Brain on AI: How to Build Your Memory Muscle Before You Borrow It with Jim Kwik
For over 30 years, @JimKwik has coached Hollywood, professional athletes, political leaders, and Harvard University on how to learn faster and think sharper — and in this episode, he tackles the question sitting underneath so much of modern life: what happens to your mind muscle when every cognitive task gets handed off to ChatGPT or Claude?
The good news: your brain, like your muscles, adapts to the demands placed upon it at any age or stage. Jim explains why frustration and failure aren’t obstacles to brain training, shares his personal top ten list of brain-building habits, ranging from racket sports to language learning and volunteering. He also delves into an MIT study examining the impact of ChatGPT and introduces his own framework for using AI as a genuine cognitive partner, rather than a replacement for human brain power.
