Kara Swisher, the legendary tech journalist, has a new HBO docuseries called Kara Swisher Wants to Live Forever. Her interest in longevity is not academic. Her father died of a cerebral hemorrhage at 34, when she was five. That early confrontation with death, she says, made her “aware of death from the very beginning” and, paradoxically, happier and less scared of risk. Then, at age 49, she had a stroke caused by a hole in her heart and a blood clotting disorder. So when she turned her reporting skills on the longevity industry, she came at it from two angles: a deep personal awareness of mortality, and a tech journalist’s skepticism toward Silicon Valley’s tendency to treat the human body as a hackable machine.

Show Notes

Plus: Hyperbaric chambers, red-light therapy, mRNA, cancer research, and the surprising importance of boredom and friction.

Kara Swisher is a veteran tech journalist, host of the Pivot podcast with Scott Galloway, and one of the most influential voices covering the intersection of technology and power. Her new CNN documentary series, Kara Swisher Wants to Live Forever, takes on the longevity industry — separating genuine medical breakthroughs from the pseudoscience being sold to anyone with a credit card and a fear of aging.

Kara Swisher has been covering Silicon Valley longer than most of its billionaires have been rich — and she's watched them turn a simple fear of death into a multi-billion dollar industry of expensive, largely unproven interventions. After her own stroke at 49, she decided to investigate: what actually works, what's a grift, and what does the science really say about living longer? The result is a new CNN documentary series that's part BS-detector, part genuinely hopeful look at the medical breakthroughs that could change everything. This conversation covers both.

We talked about:

  • Why biohacking culture is basically a men's eating disorder dressed up as science
  • Bryan Johnson, Peter Attia, and what Silicon Valley gets catastrophically wrong about longevity
  • The supplements, therapies, and interventions that are mostly hype (peptides, hyperbaric chambers, red light therapy, full-body scans)
  • What VO2 max actually measures — and why it's one of the few metrics worth tracking
  • GLP-1 drugs: the real promise behind the Ozempic headlines
  • The mRNA breakthroughs that could produce a pancreatic cancer vaccine
  • Why your relationships are a more powerful longevity drug than anything you can buy
  • The case for boredom, friction, and putting your phone down
  • How thinking about death every day can make you happier and less afraid
