The Zen Of Aging: How To Stay Fit and Look Amazing As You Get Older.

Full show notes: BenGreenfieldLife.com/limitlessdaily

In this episode, you'll hear repeat guest Jim Kwik talk about cognitive offloading and where the line sits between using your phone as a second brain and letting your own memory go slack. We dig into the MIT study that scanned essay writers' brains and found the ChatGPT group remembered the least of what they wrote, what London cabbies' brains looked like before satellite navigation, why movement drives brain-derived neurotrophic factor (BDNF), and why racket sports and dance sit at the top of the longevity list. You'll also learn Jim's BUILD framework for using AI as a critic rather than an answer machine, how to write an affirmation your brain will not immediately reject, the white bear effect that makes "don't check your phone" the least useful instruction you can give yourself, why the 15 to 45 minutes of sleep inertia after you wake carries more weight than any other window in your day, and the four daily basics Jim ranks above every device in his house. We close with the 40 Hz gamma protocol I now use in the early afternoon, and the surprising effect it's had on how quickly I fall asleep at night. All of this comes straight out of Jim's new book, Limitless Daily, designed to give you one simple, actionable lesson each day for an entire year.

A Memory & Learning Expert Reveals His Secrets To Training Your Brain & MASTERING Your Mind, With Jim Kwik

Full show notes: BenGreenfieldLife.com/jubilee

In this episode, John Jubilee makes the case that almost everything you have been told about hydration is beside the point. His argument is that the water is not the problem, the cell is: that a membrane gets progressively harder to penetrate as you age, that your water and your supplements simply bounce off it, and that until you change the membrane itself, nothing else you do gets in. He arrived at that after a decade of doing everything right, a gallon of water a day and a thousand dollars a month in supplements, and still having high blood pressure and no cartilage left in either knee. 

You'll hear the question he asked every one of his doctors that none of them could answer, the $11,000 machine he bought in 1997 to answer it himself, and the Energized Health protocol he built out of it. You'll also get the practical layer that costs nothing: the three steps he tells everyone to start with, the balls-of-your-feet walking trick and the soleus study behind it, his case for MSM, and why he refuses to recommend alkaline, structured, or reverse osmosis water. Then it turns personal, into cellular trauma, the ACE study, and why he believes a flawless diet still leaves something unaddressed.

This Guy Healed Knee Arthritis *Without* Surgery (& Chest-Pressed 555lbs For 14 Reps) - Cellular Hydration Secrets With John Jubilee

Full show notes: bengreenfieldlife.com/bolt

In this episode, Chandler Bolt and I talk about how we've each landed on almost identical daily systems for running a company, and the one place we still disagree. Chandler makes the case that a book is a business asset rather than an income stream, explains what it actually costs to buy your way onto the New York Times list, and then walks through the routine underneath all of it: a nap he hasn't skipped in years, a morning he refuses to let anyone schedule over, and a phone that geofences itself into work mode the moment he arrives at the office.
 
You'll also hear why he self-experiments relentlessly yet refuses to wear a tracker. We get into the two metrics worth watching if you track nothing else, why the 30-minute nap ceiling is weaker science than you've been told, why a hot tub is harder on fertility than a sauna, what overhead LED lighting does to your afternoon and the BlockBlueLight bulbs I use instead, and why a manual WALKOLUTION treadmill desk beats a motorized one. Chandler also shares the airplane movement trick that got him mistaken for a lunatic by a stranger who later became a friend. Then we close on communication: being a default no, replacing calls with voice memos, and using SocialSweep to surface the connections already sitting in your phone.
