Welcome to another wide-ranging “Random Show” episode I recorded with my close friend Kevin Rose (digg.com)!

We cover Kevin’s sobriety journey and marking 100 days without alcohol, my results with the ketogenic diet and intermittent fasting, GLP-1 agonists, home defense and security, the future of Venture Capital, authenticating yourself online, AI, the cultural shift toward human-to-human connection, Roblox, and more.





Please enjoy!

This episode is brought to you by AG1! I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. Right now, you’ll get a 1-year supply of Vitamin D free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit DrinkAG1.com/Tim to claim this special offer today and receive your 1-year supply of Vitamin D (and 5 free AG1 travel packs) with your first subscription purchase! 










This episode is brought to you by David Protein Bars! I’m always on the hunt for protein sources that don’t require sacrifices in taste or nutrition. That’s why I love the protein bars from David. With David protein bars, you get the fewest calories for the most protein, ever. David has 28g of protein, 150 calories, and 0g of sugar. Their bars come in six delicious flavors, all worth trying, and I’ll often throw them in my bag for protein on the go. And now, listeners of The Tim Ferriss Show who buy four boxes get a fifth box for free. Try them for yourself at DavidProtein.com/Tim.










This episode is brought to you by Momentous high-quality creatine! I’ve long benefitted from creatine for athletic and gym performance, and now I’m increasing my daily intake to enjoy the cognitive benefits as well. A pilot study in Alzheimer’s patients demonstrated that supplementing can increase brain creatine levels in just 8 weeks, improving measures of memory, reasoning, and attention. And a double-blind, placebo-controlled study found that creatine can restore aspects of memory and attention within hours in adults who are sleep deprived. I use Momentous Creatine made with Creapure®, which is sourced from Germany and has the strictest lab standards to ensure it’s at least 99.9% pure. And try Momentous’s whey protein isolate and magnesium threonate, all of which meet their same, exacting standards. Check out Momentous for yourself and get 35% off your first subscription order with code TIM at LiveMomentous.com/Tim









Want to hear the last time KevKev and I did one of these Random Shows? Listen to our conversation here in which we discussed maintaining sobriety with a partner who still drinks, Taiwanese tea, finding magic in the ordinary, the ups and downs of accelerated TMS, the intersection of AI and life sciences, deepfaked side hustlers, when meditation retreats go right (and wrong), and much more.
