Tim Ferriss’s Sabbatical, Kevin Rose Tries a Medium, Fitness Tools, and More — The Tim Ferriss Show

In this Random Show, Tim Ferriss explains why he took his first podcast sabbatical in ten years to draft a new book, and how he wants to reshape his interview approach going forward. The pair cover skincare experiments like the vampire facial, Tim's systematic approach to dating and starting a family, and rucking and back-pain training tools. They dive deep into longevity science, including the protein klotho as a potential Alzheimer's breakthrough that Kevin's fund is investing in, plus rapamycin for aging dogs. Kevin recounts an emotional session with a psychic medium about his late father, and Tim shares stories of unexplained phenomena witnessed during ayahuasca ceremonies. They close with a candid, cautionary discussion of IV and intramuscular ketamine therapy for treatment-resistant depression following Matthew Perry's death.

• Tim Ferriss reveals he took his first podcast sabbatical in 10 years (roughly four months) to write his first new book in seven years, and plans a 'barbell' guest strategy of total unknowns or huge names with little in between.
  00:01:04
• Tim explains his viral 'Romanian Vampire Protocol' Instagram post was a joke, while Kevin details actually getting a real vampire facial (PRP microneedling) at the dermatologist.
  00:10:48
• Tim openly discusses his systematic 'radical planning' approach to dating, wanting a partner in the 28-35 range who is ready and excited to build a family biologically.
  00:17:23
• Kevin reveals True Ventures is leading a large investment to bring the longevity protein klotho into human trials within about a year and a half, framing it as a potential 'Ozempic for the mind' for Alzheimer's.
  00:50:10
• Kevin recounts speaking to his dead father through a $150 psychic medium, who correctly referenced a half-sister Kevin had that was never on the internet, leaving him sobbing.
  00:59:39
• Tim describes firsthand witnessing people with no exposure speak or sing coherently for up to an hour in indigenous languages (Shipibo, Kichwa-Lamista) and a dead language during ayahuasca ceremonies.
  01:09:29
• Kevin announces an upcoming podcast where he filmed himself undergoing intramuscular ketamine treatment to demystify it as a tool for treatment-resistant depression and suicidal ideation.
  01:23:37
• Tim warns that ketamine is 'like alcohol times 100' for taking the edge off and should never be self-administered outside a clinic, citing high-functioning people who derailed their lives.
  01:30:38

• Tim got a staph infection 12 years ago after a clinic used the wrong injection site for a PRP joint injection, swelling his elbow to the size of a volleyball, and he later squirted the drained fluid at Kevin in the ER.
  00:13:04
• Tim recommends the Outdoorsmans Atlas Trainer Frame rucking system (recommended by Olympic archer Jake Kaminski) that accepts standard Olympic plates for progressive resistance.
  00:27:59
• Kevin gifts Tim a 'Feno' device, a startup product that brushes the entire mouth in 20 seconds and has built-in sensors that scan gum health to send to your dentist.
  00:35:35
• Tim, Kevin, Peter Attia, and Brian Armstrong all funded the Dog Aging Project's rapamycin study with researcher Matt Kaeberlein; Kevin's 14-year-old dog Toaster has done courses of rapamycin.
  00:46:14
• If you carry the APOE4 gene you face dramatically higher Alzheimer's risk, but being a klotho overproducer can level the playing field; in monkeys a subcutaneous klotho shot made them about 20 percent smarter for four weeks.
  00:51:18
• Kevin started a paid Substack donating 100 percent of the first month's proceeds to fund a Matt Walker sleep study on antioxidants that may repair a bad night's sleep.
  00:54:34
• Kevin donated stock to UCSF researcher Dena Dubal to fund a $50k klotho study she started about a week and a half later, illustrating how small checks can rapidly accelerate science.
  00:56:43
• Tim notes ayahuasca combines Banisteriopsis caapi vine with Psychotria viridis (chacruna), comparing the variability to spins on an old-fashioned cocktail.
  01:17:44
• The documentary 'The Birth of Sake' covers Yoshida Brewery, one of only about a thousand remaining handmade sake breweries (down from roughly 4,000 a decade ago), where workers leave families to tend sake around the clock for six months.
  01:20:25
• Addison explains the new open-source Flux AI image model came from former Stability AI team members, and despite claims you couldn't fine-tune it, training loras became possible within 24 hours of launch.
