    Denise Kirtley: Stop Chasing Your Thirties

    27/08/2026 | 46 mins.
    We're bringing back our May 2025 conversation with Denise Kirtley, the founder of Rebellion Body. As we look back on this message, Kirtley is preparing to head to the Super Age Games with the event's largest team yet, more than 50 women strong. Kirtley built her coaching business on the idea that midlife is not a decline to manage, but a version of life women get to design on purpose. In this conversation, she explains why belief, not willpower, is usually the first thing that has to change before a body does. She also gets into the backlash she receives for posting bikini photos in her fifties, her wariness about AI-generated bodies flooding social media, and why she thinks the phrase "50 is the new 30" gets the whole conversation backward. Listeners will come away with an answer to the question that stalls most people before they ever begin: what do you do on the days you don't feel motivated at all?

    "I think people think motivation is like this mythical thing that all of a sudden the clouds open and you get the sign from the heavens that ‘Now is the time.’ It doesn't work that way. You just do it."
    "We cannot worry about the things that naturally happen as we age."

    Why Coffee is Your Superfood

    20/08/2026 | 38 mins.
    Before Andrew Salisbury became captivated by the biochemistry of coffee, he set a Guinness World Record jumping out of a helicopter tethered to a bungee cord over Cancun, part of a career that has swung between call center software, extreme sports, and now one of the country's fastest-growing coffee companies. In this conversation, the founder of Purity Coffee explains why much of the coffee on the market fails basic testing for mold and heavy metals, and walks through how various factors change how much of coffee's antioxidant benefit actually reaches your cup. He makes the case that coffee's health benefits come from its polyphenols and chlorogenic acids rather than its caffeine, a distinction he says the industry gets backward. Listeners will also hear about his newest venture, a honey partnership with an indigenous community in the Amazon, and why he thinks the choice of what you drink every single day matters more than most supplements.

    Key Moments
    "It's not the caffeine in the coffee that gives you the health benefits."
    "You need to lab test [coffee] to make sure that it's free of mycotoxins."
    "I went from the million dollar sort of systems that we were selling that would take a year, year and a half, to selling 25 dollar bags of coffee."

    Kim Alexis: Fighting The Urge To Explain Yourself

    13/08/2026 | 33 mins.
    Kim Alexis, 80s supermodel turned integrative health practitioner and host of the podcast Unexpired, talks about the mindset shift that let her build a real estate career, a fitness certification, and a health practice, all after turning 64. She explains why she has chosen against surgery, how she manages her arthritis, and why she makes conscious health decisions in her weekly routine. Alexis also opens up about her instinct to over-explain herself to fans who criticize her changing appearance, and the wisdom that has slowly replaced that people-pleasing habit with peace. She closes with what keeps her looking forward at 66: a new grandson, a growing podcast, and a daily practice of gratitude.

    Dr. Kelly Stankiewicz: Lasers, Microneedles, and Age Specific Skincare

    06/08/2026 | 52 mins.
    We're revisiting a favorite conversation this week: our September 2023 sit-down with Dr. Kelly Stankiewicz, one of our go-to dermatologists. Dr. Kelly specializes in laser skin treatments that combat the effects of aging and can even create a youthful glow, if that's your jam. We also break down the four core pillars of a sound skincare routine: cleanse, exfoliate, nourish, and protect. And I asked Dr. Kelly for context around Jimmy Buffett's death and the skin cancer he battled, along with what we can all do to protect ourselves.

     Key Moments:
    “What's important is that you're hitting all four of the categories: sunscreens, antioxidants, exfoliants, and cleansers.”
    “So people, when they hear that someone has died of skin cancer, they get very concerned because skin cancer is quite common. The type that Jimmy Buffett had is very, very rare. So all of my patients who've had multiple basal cell carcinomas and squamous cell carcinomas, which don't typically metastasize, are, you know, kind of up in arms because they don't really understand the difference.”
    “When you're doing fractional resurfacing, you're decreasing your risk for skin cancer probably (or at least according to this one study) by about two times or maybe a little bit more.”

    Amy Odell: Why Gwyneth Paltrow Believes Her Own Hype

    30/07/2026 | 50 mins.
    Amy Odell, the journalist behind the biographies Anna, and the newly released Gwyneth, joins the show to trace how a $6.8 trillion wellness industry has learned to monetize our fear of aging. She explains why Gwyneth Paltrow's most outrageous claims may not be cynical marketing at all, connecting research on conspiracy belief and narcissistic traits to how someone builds and defends a brand.
    Later, The conversation turns to plastic surgery's shift from private secret to public status symbol. A facelift can change a face without changing how old people perceive it. Odell and host David Stewart also dig into the harder distinction beneath all of it: aging as a matter of physical capacity versus a matter of appearance, and why culture keeps confusing the two.

    Key Moments
    "The wellness industry is valued, according to the Global Wellness Institute, I believe at $6.8 trillion globally... It's bigger than big ag. It's bigger than big pharma."
    "I do think that [Gwyneth] believes the things that she promotes, even if they seem crazy to us... there's some research that people who believe conspiracy theories have traits of narcissism."
    "I think we live in an ageist society... there's so much money made in selling people this idea of eternal youth."
