The Random Show, Couch Edition! — Supplements, Breathing and Balance Training, and Much More!

TL;DR

Tim Ferriss and Kevin Rose share wide-ranging experiments in ketone supplements, vagus nerve stimulation, balance training, and back pain treatment.

Key Points

• 1.Delta G ketone monoesters should be treated like moonshine. The 13-butanediol component shows animal-model evidence of causing fatty liver disease; take 15g max, not the full 30g shot, and use in moderation.
• 2.Full 30g ketone ester doses can spike anxiety rather than reduce it. Tim discussed this with Dr. Rhonda Patrick, who experiences the same effect, likely due to a rapid BHB rise followed by a sharp trough.
• 3.Vagus nerve stimulation via breathing may explain many meditation benefits. Kevin Tracy's research shows VNS activates the inflammatory reflex, reducing cytokine storms; ear- or neck-based stimulation lasts ~12 hours, so twice-daily sessions provide full coverage.
• 4.HeartMath ($250) lets you watch HRV rise in real time during box breathing. Kevin demonstrated you can spike HRV by following the breathing prompt and drop it by thinking stressful thoughts, validating the coherence feedback loop.
• 5.Balance training is the top injury-prevention priority for aging. Balance boards, slacklines (Gibbon brand), and similar tools train the nervous system; Tony Hawk at mid-50s still snowboards despite needing a hip-screw surgery months earlier.
• 6.Slacklining requires sleep cycles to integrate neurologically. Kevin advises a few minutes daily rather than one long session; his kids went from falling on day one to fluent riding on day two after overnight adaptation.
• 7.Tim may have Bertilotti syndrome, a rarely diagnosed transitional vertebral segment. A nerve block with lidocaine, procaine, and Kenalog eliminated six years of precise low-back pain for five-plus days; radio frequency ablation (lasting 1–1.5 years) is the next possible step.
• 8.Emil Abrahamsson's isometric hang protocol rebuilds tendons with minimal effort. 10 seconds on, 50 seconds off, 10 rounds twice daily at 30–85% bodyweight; before/after strength tests are described as 'mind-blowing' even for elite V13 climbers.
• 9.The Nug (Friction Labs) is a pocket-sized hangboard for travel. About the size of a large bar of soap with 20–25mm grip depths, it attaches via carabiner to cable machines or plate-loading pins for single-hand isometric loading.
• 10.A Zen retreat produced 3–5 days of calm, focused attention after returning home. Tim found the 'just be still' concentration prompt from Zen master Henry Shukman far more effective for his OCD than open-monitoring labeling practices.
• 11.Vintage Japanese fireman jackets sell on Etsy for ~$92 versus $2,500+ from designers like Visvim. Kevin discovered an Etsy importer selling 1960s–70s indigo-dyed and heavy-canvas Japanese workwear including jackets, quilts, and shrine items at a fraction of retail.
