“They won't know they've had AFib, and then they present with a stroke.” — Dr. Anthony Pearson  Key Links  Dr. Anthony Pearson — The Skeptical Cardiologist: Read and subscribe to his Substack  Dr. Pearson's Updated Primer on Atrial Fibrillation: Understanding AFib, stroke prevention, and treatment options  KardiaMobile Card: Learn about the credit-card-sized personal ECG device discussed in this episode.  Apple Watch ECG and AFib Monitoring: How to use Apple's heart-monitoring features  Fish Oil and AFib Risk: Dr. Pearson's analysis of omega-3 supplements and heart health  The DECAF Trial: New research on coffee consumption and AFib recurrence  The 2026 AVANT GUARD Trial: Research comparing pulsed field ablation with antiarrhythmic medications  The OPTION Trial: Research comparing left atrial appendage closure with anticoagulation after ablation  In This Episode  You can be fit, active, and seemingly healthy—and still develop atrial fibrillation (AFib). Even more concerning? You can have it without knowing it, and a stroke may be the first warning sign.  I know firsthand. About three and a half years ago, I was diagnosed with AFib, despite nearly 20 years of running marathons and doing everything I thought I should to protect my heart.  For this AGE BETTER Deep Dive, I invited cardiologist Dr. Anthony Pearson, aka The Skeptical Cardiologist, back for a candid conversation about AFib, stroke prevention, and the treatment decisions that aren't always as straightforward as we think.  Here's what you'll learn:  What AFib actually is, why it becomes more common after 60, and why some people never experience symptoms.  How to recognize AFib before it causes serious problems, including what smartwatches, personal ECG devices, and monitoring can—and cannot—tell you.  The surprising risk factors, including genetics, endurance exercise, alcohol, and high-dose fish oil supplements—and why your morning coffee may not be the problem you think it is.  What happens after an AFib diagnosis: the difference between controlling heart rate and restoring normal rhythm, and why medication, cardioversion, or ablation may be recommended.  The pros and cons of Eliquis and other blood thinners, including bleeding risks, stroke prevention, and emerging research on whether certain carefully selected patients may be able to use anticoagulants intermittently.  The latest treatment options, including traditional and pulsed field ablation, the Watchman device, and why Dr. Pearson believes patients should sometimes question recommendations for invasive procedures.  Dr. Pearson even challenges my own decision to undergo cardiac ablation—and explains why getting a second opinion can be so important.  The bottom line: AFib is common, often silent, and potentially serious. But understanding your risk and your options can help you make better decisions with your healthcare team.  Stay Connected  If this episode helped you, please share it with a friend or family member, especially someone over 60 who may not know much about AFib.  Follow AGE BETTER wherever you listen to podcasts, and subscribe to my free AGE BETTER Cheat Sheet on Substack for more practical, science-backed ways to stay strong, healthy, and independent after 60.  Have a question or an idea for a future Age Better Deep Dive?

“You need to do something for your feet.” — Dr. Erin Futrell  We spend a lot of time thinking about strengthening our legs, our core, and our bones—but what about the muscles in our feet?  In this episode, physical therapist and researcher Dr. Erin Futrell explains why the small muscles that make up our “foot core” deserve much more attention, especially as we get older. We talk about foot strength, balance, fall risk, the surprising role our shoes may play, and the simple exercises that can help us keep our feet strong and responsive.   KEY LINKS  Learn more about Dr. Erin Futrell and the FiTT Lab HERE   Watch Dr. Futrell’s Foot-Strengthening / Toe Yoga Video HERE   Read Dr. Futrell’s 2026 study on minimal footwear, balance and fall risk in older adults HERE   Read Dr. Futrell’s 2024 study on long-term minimal footwear use in older adults HERE    Read USPSTF report on fall prevention HERE  Read study on minimal footwear and osteoarthritis HERE  Learn more about The Foot Core System research HERE   Get the toe spacers Barbara mentions in the episode HERE    WHAT YOU’LL LEARN  What the “foot core” is—and why these small muscles matter for stability and balance.  What happens to our feet as we get older, and why it is not too late to strengthen them.  Simple “toe yoga” exercises—including toe lifts, toe spreading and the short-foot or doming exercise.  What Dr. Futrell’s research found when older adults trained their feet or gradually wore minimally cushioned footwear.  Why proprioception—our ability to sense where our body is in space—may be one of the most fascinating connections between our feet and our balance.   Why more cushioning and support isn’t necessarily better for everyone—and why any transition to less supportive footwear needs to happen gradually.  How stronger, more responsive feet may help us keep doing the thing that matters most as we age: moving.   This conversation completely changed the way I think about my own feet—and I have a feeling it will do the same for you.  Listen or watch now, check the show notes for Dr. Futrell’s exercise video and research, and then take five minutes today to give your feet a workout.  And if you found this episode helpful, please follow AGE BETTER, leave a rating or review, and share it with someone who wants to stay strong, steady and active for years to come.

She also addresses one of the biggest questions women ask: If I’m already in my 60s or 70s and I haven’t been strength training, have I waited too long? Her answer is reassuring: you can still build muscle and get stronger.   You’ll also hear why muscle matters for far more than appearance, what kinds of strength and impact exercise actually challenge bone, how to adapt exercise when arthritis gets in the way, why balance and agility deserve a place in your routine, and how a DXA scan can help you make more informed decisions about your health.   Most importantly, this conversation is about what you can still do right now to protect your bones, preserve your strength and keep yourself moving confidently for years to come.  One More Thing  World Osteoporosis Day is a good reminder to make bone health part of your overall health plan.

“Resistance training and protein are the new fountain of youth.” — Dr. Ian Smith  What changes about the way we should eat and exercise during menopause—and for all the decades that follow?  In this episode of AGE BETTER, I sit down with physician and bestselling author Dr. Ian K. Smith for a lively, practical conversation about his new book, The New Menopause Kitchen. We talk about the nutrients that become especially important during and after menopause, why he created a flexible 10-week eating plan, and how Rachael Ray’s recipes turn those nutritional principles into real food you’ll actually want to eat.  But this isn’t just a conversation about food. Dr. Ian believes nutrition and exercise are a “one-two punch,” which is why the book also includes his Meno-Cise exercise plan—with a particular focus on maintaining muscle, protecting bone, and making movement doable and sustainable.  KEY LINKS  Read “The New Menopause Kitchen” by Dr. Ian K.

“I want to proceed unfinished . . .think of the changes as adaptations, not surrender.” — Kathryn Grody  KEY LINKS  Kathryn Grody’s one-woman show, The Unexpected 3rd — October 13–November 1 at George Street Playhouse The Unexpected 3rd — tickets and information  Don’t Listen to Us with Mandy Patinkin and Kathryn Grody — Kathryn and Mandy’s podcast with their son, Gideon Listen to Don’t Listen to Us  “The Layers” by Stanley Kunitz — the poem Kathryn reads during our conversation Read “The Layers”  How Not to F*ck Up Your Face by Valerie Monroe Visit Valerie Monroe’s Substack  What does getting older actually feel like?  At 79, award-winning actress and writer Kathryn Grody isn’t interested in pretending she has aging figured out. She’s funny about it, angry about parts of it, grateful for it—and determined to keep discovering who she is.  Kathryn joins me for a wonderfully candid conversation about entering what she calls her “third and final act,” which inspired her one-woman show, The Unexpected 3rd. We talk about the strange experience of feeling like yourself while suddenly being treated as “old,” why allowing her hair to go gray felt almost radical, and what happens when the world begins making assumptions about what you can—and can’t—do.  We also talk about strength and changing bodies, needing more time to recharge, bringing new people into your life as old friends are lost, the fear of mortality, marriage and family, and the unexpected social-media fame that came when her son Gideon began filming Kathryn and her husband, Mandy Patinkin, simply being themselves.  And then the conversation goes somewhere deeper: How do we acknowledge what is hard about aging without allowing fear and loss to become the center of our lives?  Kathryn’s answer has stayed with me. Stay curious. Keep adapting. Keep participating. Keep making room for new experiences. And above all, don’t assume you’re finished.  If this conversation speaks to you, please share it with a friend who is thinking about what her own next chapter might look like.

“One of the biggest mistakes I’ve made is overvaluing status and undervaluing purpose. And as I get older, I hope to switch that out.” — Maggie Rowe  KEY LINKS  Lisen to ‘50 Words for Snow’ podcast HERE  Learn more about Maggie Rowe HERE   Read AGE BETTER CHEAT SHEET newsletter HERE    What if some of the problem with aging is simply that we don’t have good enough words for it?  English gives us elderly, senior, over the hill, anti-aging—and the particularly maddening “you look good for your age.” But in other languages, there are words that describe growing older very differently: as ripening, accumulating wisdom and experience, becoming more grounded, letting go of old burdens, and approaching life with renewed curiosity and wonder.  My guest today is writer and performer Maggie Rowe, co-host of the fascinating podcast 50 Words for Snow, which explores words from other languages that have no direct English equivalent.  Maggie introduces me to words and ideas I wish we had been using all along—including a Japanese concept that compares aging to ripening and becoming more complex and layered with time, another that describes the treasure trove of experience we accumulate through life, and shoshin, or “beginner’s mind”: the ability to approach life with curiosity instead of assuming we already know everything.  We also have some fun deciding which aging words deserve to be retired forever.  But the deeper question is one worth thinking about: Do the words we use merely describe aging—or do they influence what we expect aging to be?  Because if the language surrounding getting older is mostly about decline and loss, it’s easy to start believing that story. What happens when we replace some of those words with ones that recognize what can actually increase with age—perspective, freedom, purpose, curiosity, self-knowledge and the ability to appreciate our lives?  This conversation may make you think differently about the words you use to describe yourself—and this stage of your life.  Listen to this episode and then tell me: What word would YOU choose to describe growing older?  Send me your word at [email protected] or share it with me on social media.  And if this episode made you think, please follow AGE BETTER, leave a rating or review, and share it with a friend.Those small actions make a huge difference in helping more women discover the show.  And don’t forget to sign up for the AGE BETTER CHEAT SHEET for more of the ideas, research and practical strategies that can help all of us age better.

“For vaginal estrogen . . . there’s no window of timing. If you’re 80 years old and your body has not seen estrogen in 30 years, you can still start local vaginal estrogen. It’s not too late. You can start.” — Dr. Margaret Nachtigall  We talk a lot about protecting our hearts, our brains, and our bones as we get older. But what about vaginal health?  In this episode of AGE BETTER, Dr. Margaret Nachtigall joins me to talk about what really happens to the vagina and urinary tract after menopause — and, more importantly, what we can do about it.  We cover vaginal dryness, burning and discomfort; why urinary urgency and recurrent UTIs can be connected to menopause; when symptoms are normal and when they’re a red flag; and the treatments that can make a real difference. Dr. Margaret explains the role of local vaginal estrogen, hyaluronic acid, moisturizers and lubricants, pelvic floor physical therapy, and other options — including what women with a history of breast cancer should discuss with their medical team.   We also talk about sex after 60, STI protection with a new partner, pelvic exams as we age, and one message I especially want women to hear: you do not have to simply accept vaginal discomfort as part of getting older. There are treatments, and it is never too late to ask for help.  If you’re in your 60s, 70s or beyond — or care about someone who is — this is an important conversation to hear and share.  Listen now, and then talk with your healthcare provider about what makes sense for you.  Are you loving AGE BETTER?

“Your doctor can be the expert on the medicine. But you are still the expert on the life you’re trying to protect.” – Barbara Hannah Grufferman  KEY LINKS  The original study in PLOS One is HERE   AGE BETTER CHEAT SHEET on Substack is HERE   What do we really want as we get older—more years, or better years?  A fascinating new study of more than 6,000 adults over 50 asked people to make some surprisingly personal choices about aging, health, quality of life, independence, and who should have the final say when medical decisions need to be made.  In this solo episode, I unpack the findings that caught my attention most—especially what women said about quality of life versus simply living longer, why what our bodies can do becomes increasingly important as we age, and why maintaining a voice in our own healthcare matters.  I also share the experience that fundamentally changed the way I think about physical function and independence: watching my mother’s world become smaller after a hip fracture.  You’ll come away with a different way to think about longevity—not simply as adding years, but as protecting your ability to live the life you want for as long as possible. And I’ll give you one question to ask yourself that can help clarify what you’re really trying to protect as you get older.  If this episode makes you think, share it with another woman and ask her: What is the one thing you most want to protect as you get older?  And please follow AGE BETTER with Barbara Hannah Grufferman on Apple Podcasts, Spotify, or wherever you listen. It’s one of the easiest ways to help more women find the show.

"Four minutes a day works . . . but not if you are an average or above average person in terms of physical activity level." — Dr. Jocelyn Wittstein  You've seen the headline everywhere: just four minutes of exercise a day is enough. There's a real study behind it — a randomized trial published in PLOS ONE — and the results are genuinely impressive. But the fine print matters. In the first episode of a new occasional series, I put a headline-making study under the microscope with orthopedic surgeon and sports medicine specialist Dr. Jocelyn Wittstein of Duke, who gives it to us straight: yes, no, or yes . . . BUT.  KEY LINKS  The study: "4 minutes of daily exercise" trial (PLOS ONE) is HERE   Dr. Wittstein's book: The Complete Bone and Joint Health Plan is HERE   Follow Dr. Jocelyn Wittstein on Instagram HERE   My AARP article interviewing Dr. Benjamin Levine on reversing heart age is HERE   My AARP article on the Japanese Interval Walking Training program is HERE   The Age Better Cheat Sheet newsletter on Substack is HERE   WHAT YOU'LL LEARN  What the study actually found — and why it applies to people who are inactive with existing mobility limits, not to everyone  The 10-second single-leg balance test, and the eye-opening research on what being able to pass it predicts  The sit-to-stand benchmark Dr. Wittstein checks in clinic — can you get out of a chair without using your arms?  Why the real headline may be compliance: participants did the workout 81% of days for three months  Why four minutes is NOT enough for bone health, heart health, or body composition — and what the research says actually protects your bones  The 7,000-steps finding that's replacing the 10,000-steps myth  "Exercise snacks": how one-minute bouts of movement throughout the day add up  Joint-friendly ways to get real intensity: the Norwegian 4x4, the air bike, Japanese interval walking, and incline treadmill walking that spares your knees  THE BOTTOM LINE  Something is better than nothing — but where you start determines what four minutes can do for you. If you're just getting going, this study is proof that a small, doable daily habit creates meaningful change. If you're already active, keep going: the benefits of exercise are dose-dependent, and four minutes won't maintain what you've built.  LET'S KEEP GOING  If this episode was useful, share it with a friend who needs to hear it, and follow AGE BETTER wherever you listen so you never miss an episode.
