Is Doping an Obstacle: Spartan World Championship Exclusive

Full show notes:BenGreenfieldLife.com/AGIpodcast

In this episode, you'll hear how artificial intelligence is actually being pointed at aging right now, including an algorithm picking which Chinese herbs extend a fruit fly's life, plus whether the biological age test you just paid for means anything at all.

My guest is Dr. Ben Goertzel, who popularized the term artificial general intelligence, runs a decentralized AI network, and is chief scientist at Hanson Robotics. We get into the long-lived fruit flies his team works on at Genescient, the roughly five traditional Chinese herbs an AI selected from a database and combined in ways that more than double a middle-aged fly's life, and why the AI mixes them in combinations no Chinese medicine practitioner ever would. You'll also learn why he says today's biological age tests are "a little dodgy," why large language models keep handing you the existing literature instead of generating new science, and what the extracellular matrix has to do with whether your whole body is aging well. We close on the engineered enzymes he thinks will eventually re-sculpt the genome of every tissue in your body, my own follistatin gene therapy result, and the band he plays keyboards in with a humanoid robot lead singer.

This Man Thinks "AGI" Could Allow Humans To Live Forever, With Dr. Ben Goertzel

Full show notes: BenGreenfieldLife.com/506

In this episode, you'll discover three things I've been asked about constantly: whether the melatonin heart failure headline is worth worrying about, how much sleep is actually too much or too little, and the shortest route to a higher VO2 max.

I break down what the melatonin study did and did not reveal, why a key prescription detail changes how the findings should be interpreted, and why I still use high-dose melatonin for jet lag. Then I move to VO2 max, including the Norwegian 4x4 explained the way I used to coach it, what the sprint interval research says about doing it faster, and the tools that work beyond exercise, from heat acclimation to altitude to correcting an iron deficiency. You'll also hear what a new Nature study of half a million people found about the 6.4 to 7.8 hour sleep window, and why I still sleep less than that on purpose.

Finally, fertility for men and women. On the male side, scrotal temperature, timing intercourse around ovulation, the lubricant problem nobody mentions, and the supplements with real human data behind them, from L-carnitine and CoQ10 to zinc and shilajit (use code GREENFIELD for free shipping). On the female side, ovulation tracking, acupuncture, CoQ10 before egg retrieval, and inositol. Plus how to preserve fertility if you're on testosterone replacement therapy (TRT).

How To Increase Fertility (For Males & Females!), How Much Sleep Is Too Much (Or Too Little)? & A "Minimalist" Approach To Increasing VO2 Max! Solosode #506

Full show notes:BenGreenfieldLife.com/gutsolution

In this episode, you'll meet Josh Dech, a former paramedic turned Crohn's and colitis consultant who argues that all three things Western medicine says about inflammatory bowel disease are wrong: it's not genetic, not classically autoimmune, and not idiopathic. We walk the research trail from a 1988 Swedish twin study through the NOD2 gene to the genome-wide studies that mapped hundreds of risk loci and still explained only a sliver of the disease, and into the numbers that worry him most, where the West has 6% of the world's population but 60% of its bowel disease. You'll also get the practical half: his sequence to help stop the active cause first, then how he suggests opening the seven drainage pathways, why he takes a full history before ordering a single test, where peptides belong, what is really coming out of people during a parasite cleanse, and why $30,000 fecal transplants keep failing. Near the end, it turns personal and a little gross, into my own dairy problem and the biomechanics of a proper bowel movement.
