Brain health is the next frontier of healthcare, and we don’t have to wait for a miracle drug. The breakthrough at our fingertips, which is scalable and available to everyone, is applying what we already know: that daily behaviors can improve our brain health, and making small daily changes can transform what’s possible for our brain now and decades from now. Here’s what the science makes clear: Food: The brain is the hungriest, thirstiest organ in the body. It makes up just 2% of body weight, but requires 20% of your body’s primary fuel. Movement: Exercise — even low-intensity movement — is a powerful counterbalance for slowing cognitive decline. Sleep: Sleep functions as a kind of cleaning cycle for the brain, filtering out harmful proteins connected to Alzheimer's. Stress management: Over the long term, cortisol can kill neurons and shrink brain regions, especially those connected to learning, memory and decision-making. Connection: The human brain rewards us for connection and punishes us for isolation. I write about this in my latest piece for @TIME: bit.ly/4m8Tq8U

Given that many of us can take our work with us wherever we go, it’s never been harder to set boundaries around our non-work lives. That’s what @GuyWinch's new book, "Mind over Grind: How to Break Free When Work Hijacks Your Life,” is all about. As he writes, "Most of us spend our workday sitting and looking at screens. What do we do to recover from our screen-heavy workday? We sit and look at screens.” You can read an excerpt here: community.thriveglobal.com/how-to-set-bou…

The transformative use of AI in healthcare isn't just about discovering new drugs and treatments — it's also about applying the known science to our daily behaviors in new ways. A great example comes from a recent study by Dr. Jeffrey Mechanick and his fellow researchers who looked at the impact of AI lifestyle interventions on those with Type 2 diabetes. As they note, we know that behavior change can improve health outcomes, but in the real world, behavior change is challenging. It's also something that AI, with its power of personalization, is uniquely suited for. In the study, the group of participants given personalized AI-driven recommendations had "significant improvements in glycemic control, weight loss, and quality of life." And they were also able to use less medication. It's proof that AI is turning behavior change into a scalable healthcare intervention. You can read the study here: catalyst.nejm.org/doi/full/10.10…

From the time my mother taught me yoga as a little girl, yoga has been an important part of my life, as has running, hiking and most recently, strength training. The beauty is that our relationship with movement can change (and, thankfully, yoga wear can, too!). Today, I'm less likely to be found standing on my head and more likely to be found deadlifting! And I love to pair a binge-worthy TV show with a treadmill or stationary bike session. What’s one small way you can bring more movement into your day?

Our attention is indeed our most valuable resource.

How do you know when it's time to take a leap? I did exactly that when I left The Huffington Post (@HuffPost) in 2016 to found @Thrive Global, helping people adopt healthy habits that drive better health outcomes, engagement, and productivity — one Microstep at a time.  Thanks so much to @anuduggalnyc for the great conversation on @fcubedvc’s The Two Percent podcast. We talked about taking risks, redefining success and what it takes to build a company that truly meets the moment. Listen here: youtube.com/watch?v=uevFtb…

On a walk with a friend over the weekend, she introduced me to @PictureThisAI, an app that you point toward a plant or a tree, and it tells you everything you want to know about the plant — and anything else you want to know about it. I love it, but I promise not to get addicted to it because there is nothing better than phone-free walks!

We’ve gotten longevity all wrong. Not the goal of longevity, but the way we’re trying to achieve it. That’s the point of the new book Push: Unlock the Science of Fitness Motivation to Embrace Health and Longevity, by @drjordanmetzl, a sports-medicine physician at New York’s Hospital for Special Surgery. As Dr. Metzl shows, the longevity business may be booming but our health isn’t. Americans now spend over a decade of their lives in poor health — that’s the gap between lifespan and healthspan. But the solution isn’t more trendy health hacks. The secret to longevity is our daily behaviors: what we eat, how much we move, how we sleep and connect socially. And progress can be achieved in daily Microsteps. As Dr. Metzl says, “The future of longevity isn’t about cheating death — it’s about the habits of living well right now.” You can read his recent piece in @TheAtlantic here: theatlantic.com/health/2026/02…

Among the advice I shared for those early in their careers: quiet that obnoxious roommate living in our heads! I am a ruminator, and it took me years to learn to deal with this voice of negativity that criticizes us, puts us down and focuses on our mistakes. The first step is acknowledging that that voice isn’t you and it’s not the truth. One of the Microsteps we have at @Thrive is to set aside a specific time (even 5 minutes) each week dedicated to worry time. It helps us remain more focused on the present moment and reduce the amount of worry in our lives!

Great to be with Monica Mandelli for a conversation at @KKR_Co in celebration of Women's History Month.

Dr. Tommy Wood's new book “The Stimulated Mind” is out today, and it gives people a practical toolkit to improve their cognitive function on a day-to-day basis while decreasing their long-term risk of dementia.  “Every one of us has the ability to dramatically improve our brain health and cognitive function today by doing things that are simple and enjoyable,” he writes. “And most importantly, it’s never too late to start.” And the book provides plenty of Microsteps to guide us. Brain health is at the heart of the zeitgeist. And with small changes in our daily behaviors, we all have the power to make it our own personal moonshot. You can find out more about @DrRagnar's book here: drtommywood.com/stimulated-mind

For more than 50 years, Kleiner Perkins has partnered with founders at moments of inflection. AI is reshaping every industry from the ground up, faster than anything we've seen before. This is the moment to build. Today, we're proud to announce KP22, our twenty-second venture fund: $1 billion to back early-stage companies, alongside $2.5 billion in growth funds to back high-inflection, category-defining businesses. A moment like this is where the most enduring companies take root. Deep founder relationships and hands-on support matter more than ever, and we believe in lean investment and portfolio operating teams that work on founder time to deliver exactly that. We're so grateful to the founders and LPs who have trusted us over the years. We couldn't be more excited to partner with the next generation of history-making companies.

"How might a home shape the health of its inhabitants over decades?" This is the question @dianabudds and the @ArchDigest team asked for their latest piece on designing homes for longer, healthier lives. Here is how I have integrated certain things into my home that have an impact on my health: a treadmill, a bike and an elliptical. Because I have an addictive personality, habit stacking is a way to use that to my advantage! So I only allow myself to binge watch my favorite shows on one of these three! So I’m currently sweating my way through The Pitt! And my @Thrive Global Phone Bed Charging Station has been game-changing — it allows me to tuck in my phone outside my bedroom and reunite with my phone in the morning, when my phone and I are both fully recharged! And yes, the bed includes a mini blanket! architecturaldigest.com/story/what-lon…

Do you check your phone 144 times a day? If so, you’re in line with the average American (according to a survey by DemandSage). Not only that, but nearly 90% of us reach for our phones within 10 minutes of waking up, and more than half of us say we’re addicted. But maybe the tide is turning. Kate Lindsay recently wrote on her Substack newsletter Embedded that being chronically online is no longer cool and that “our lack of screen time is a new social indicator.” thedailyvalet.com/p/the-daily-va… So how about you – are you less tethered to your phone than in recent years?

Happy, happy birthday to my darling sister and best friend, @AgapiSays! There’s nothing like basking in our sisterly love while walking (or boating) through this life together — what a gift it is being on this journey with you! 💜

So how about you — would you support a ban on phones in bars and restaurants?

Should restaurants and bars ban phones? Does the phenomenon of everybody checking their phones dozens of times long before the check comes bother you? For @InsideHook, Kathleen Willcox makes the case. As she notes, the rise in phones was accompanied by a rise in loneliness. Willcox cites the fact that the portion of Americans dining alone is at a record high, with people sharing an average of only 7.9 meals with others per week. And Americans are spending less time with other people than at any time going back to 1965, when the data started being collected. As one restaurateur put it, “You can be in a room full of people and still feel like no one’s really there because everyone is half on their phone. Screens cut through the natural rhythm of a space — the generosity, the spontaneity, that shared pulse that makes hospitality feel special. After so many years in this industry, you really see the difference when guests stay present. The whole room changes. The experience becomes real again.” insidehook.com/cocktails/bars…

Now that #tradwife has entered the collective chat, what does it mean? According to @sherylsandberg, writing in the most recent edition of @LeanInOrg's great newsletter “The Lead,” the trend is actually being driven by a much older phenomenon women have to deal with: guilt. The majority of women work outside the home and the #tradwife movement is a subtle signal that to be a good wife/mother/partner you shouldn’t. With working mothers it feels like they take the baby out and they put the guilt in. But as Sandberg notes, working outside the home doesn’t diminish your other roles. “Let’s keep the past where it belongs—in the past,” she writes. “Instead, let’s focus on a future where each woman has the chance to pursue the life she wants, develop the talents she has...and achieve the goals that matter most to her.” Here’s the whole thing: bit.ly/4uFkOPV

Revisionist history has gone too far! As part of a “Popular Science” series on little-known science stories, Andrew Coletti concludes that the Oracle of Delphi “was just high on gas fumes.” As a Greek immigrant, and thus a devotee of ancient Greek wisdom, those are fighting words. On the other hand, Coletti seems to have the goods on the Greek priestess. Plutarch’s reports about the Oracle noted that the priestess would sit on a stool near a natural spring that produced a sweet-smelling gas, or “pneuma.” Years ago, in a hunt for what that gas could be, researchers John Hale and Jelle Zeilinga de Boer examined a fault underneath the temple. Samples of the bedrock tested positive for ethylene, a gas that was used as an anesthetic in the past. What does it do at lower doses? “People under the influence of ethylene remain lucid and responsive, but may speak or behave strangely,” writes Coletti. Which is why Hale pronounced ethylene a “perfect match” for pneuma. As Wordsworth wrote, “Let Nature be your teacher.” Though maybe not if you’re sitting near a plume of ethylene.
