Maybe you
think about it
. Maybe you don’t. But the word “longevity” is everywhere, appearing on your
skin care
bottles, at your gym, and even on the labels for your dog’s food. Welcome to The Long Game, a series exploring longevity today and what it means to live better.
It’s 9 A.M. and
Kayla Barnes-Lentz
has already had, by any reasonable definition,
a day
. When I arrive at her door, about 40 minutes from downtown Austin, she begins by listing what I’ve missed since she awoke, without an alarm, at 4:50 A.M. She brushed her teeth,
water-flossed
, and used an in-mouth red-light device to kill oral bacteria. She completed a
Pulse PEMF
(Pulsed Electromagnetic Field) therapy session. She breathed with intention. She prayed. At sunrise, she walked around her gated community with her husband, Warren, to optimize her circadian rhythm. She drank a coffee with whey protein, collagen peptides, creatine,
colostrum
, and
NAD
powder. She strength-trained and rode her CAROL, an AI-powered resistance bike. She posted that workout for her 595,000 Instagram followers. She sweated in her
infrared
sauna. She showered. She swallowed her morning supplements: a prenatal multivitamin to optimize her fertility, plus fish oils, CoQ10, and magnesium.
This morning routine isn’t a Herculean feat for Barnes-Lentz. The steps constitute a mere sliver of what the 35-year-old biohacker calls her protocol: the labs, results, schedules, foods, devices, procedures, therapies, and principles she embraces daily, weekly, quarterly, biannually, and annually to ensure she lives the healthiest, longest life possible. She documents it all in dizzying detail
on her website
, where she bills herself as the “most publicly measured” woman in the world. “Women have such unique biology and concerns related to longevity,” Barnes-Lentz tells me as we pad around her home, shoes off. “A lot of the audiences across the board in biohacking or longevity have actually been women,” she continues. “We’re just all trying to figure it out on our own.”
To understand Kayla Barnes-Lentz and the world she inhabits, one must start with Bryan Johnson—“the most measured man in history”—who has become the face of biohacking and longevity in the American cultural zeitgeist.
During the pandemic, the tech entrepreneur began documenting his quest to live forever on social media. Virality eventually followed, as did a steady drumbeat of headlines about both his extreme, costly protocol and personal controversies, including but not limited to
“multi-generational plasma transfusions”
with his father and then-teenage son; meticulous detailing of
his erections
; and a live-streamed
five-hour
psilocybin trip.
Though other men occupy adjacent seats at Johnson’s proverbial cafeteria table—from fellow biohackers and longevity researchers like Dave Asprey, Peter Attia, and Peter Diamandis, to noted industry investors including Peter Thiel, Jeff Bezos, and OpenAI CEO Sam Altman—it is Johnson, 48, who has arguably become the movement’s avatar. It would be easy, at this juncture, to dismiss all of this as another Silicon Valley-bro space race, this time to cheat death. I did—at least at first.
Things changed last February, when I attended Johnson’s Don’t Die Summit at Manhattan’s Javits Center as a media guest of Cellcollabs, a Swedish biotech company specializing in large-scale production of mesenchymal stem cells. At the daylong event, I expected to feel adrift in a sea of men rabid for the secrets to eternal life. Instead, women made up around half the crowd, I estimated, though only one presented:
Kate Tolo
, Johnson’s 30-year-old co-founder and, as the pair would announce this past December, his romantic partner of three years. When Tolo stepped into the spotlight to share her own story and health insights, the other women exploded with excitement. They felt seen, I supposed.

Kate Tolo and Bryan Johnson.
Their passion mirrors the current moment. Globally, people are living longer, and women are outliving men by
more than five years
—but they often spend a larger share of those later years in
poor health
. These findings have, in part, fueled a growing push from the private sector to invest in women’s health, in a world where they have historically been underrepresented in medical research. One recent analysis by Market Research Future estimated the longevity market at $21.3 billion in 2024, projecting growth to $63 billion by 2035. Overlapping industries aimed at women are growing in parallel: According to Grand View Research, the global women’s health market was valued at $49.3 billion in 2024 and is expected to reach $68.5 billion by 2030. Also per Grand View, FemTech—the tech- and innovation-driven subset spanning menstrual care and reproductive and post-reproductive health—was valued at roughly $39.3 billion in 2024, with
