Portal argues that people have desensitised themselves from fine-grained emotional experience — like real gratitude or remorse — and that recovering this granularity requires deliberate practice, just as recovering smell after COVID does.

Huberman introduces the kumbhaka practice described by Dr. K: meditating on the pause between breaths rather than on the inhale or exhale. Portal's response reveals what the practice actually discovers — there is no single point where the pendulum reverses direction. The closer you look, the more the transition dissolves into a continuum. [1] — Ido Portal "Kumbhaka — the pause between breath cycles — reveals something radical: there is no single moment where the direction changes. The more you…" 1:43:18 He illustrates multi-stability with his own experience standing in cold ocean water in Yallingup, Australia: by staying and investigating the sensation of cold, he eventually found a heat underneath it, then learned to lock between the two perceptions at will. Portal connects this to fighting applications — reading polyrhythms in an opponent's footwork — and to reading Borges short stories in a hot tub. Huberman then brings in Daiyu Lin's ventromedial hypothalamus research showing that mating and aggression are driven by antagonistic neuron populations in the same structure — each suppresses the other, then rebounds. The universal push-pull architecture of neural circuits mirrors Portal's multi-stability framework.
Asking 'how do I fit movement practice into my 30-minute slot?' is the wrong frame. The entire rest of the day — cooking, listening, commuting — is movement practice. The question is whether you're present to it or not.
Despite predictions that AI would eliminate radiologists, the Mayo Clinic's radiology staff grew 55% after AI arrived at reading scans.
In 2025, radiology was the second-highest paid medical specialty in America, with average incomes 48% higher than a decade ago.
A study across 3 hospitals found radiologists spent only 36% of their time reading scans — the part AI can do — with the rest being human judgment.
Robert Greene notes that one in six Americans is on some form of drug to deal with depression, suggesting a deep societal disconnection from meaningful experience.
Spencer Greenberg and Jeremy Stevenson analyzed almost 500 self-improvement techniques and found they all reduce to just 12 underlying psychological drivers.
Cold exposure has good short-term alertness benefits but the evidence base for long-term health benefits is much weaker than popularly believed.
In a randomized study of 20 habit-formation techniques run on hundreds of people, almost none of the techniques produced statistically meaningful results.
People given a tiny-habit fallback option (e.g. 10 squats instead of gym) were actually MORE successful at completing the full habit, not less.
The most effective habit-formation technique was 'habit reflection' — recalling a past successful habit, writing down what helped, then applying those lessons to a new habit.
