Summary

Gravity is everywhere—yet we rarely think about its impact on our health. In this episode, Dr. Brennan Spiegel, UCLA Professor and author of the groundbreaking new book Pull: How Gravity Shapes Your Body, Steadies the Mind, and Guides Our Health, joins John R. Miles to reframe gravity not just as a force of physics, but as a hidden variable in human health and resilience.

They explore how posture, balance, grip strength, and heart rate variability reveal your “gravity relationship,” why serotonin is really a “gravity management substance,” and how gut health, mood, and even mental states like anxiety and depression are shaped by gravitational forces. Spiegel introduces concepts like “gravity intolerance,” “graviception,” and “gravi types,” showing how simple practices, from standing desks and rucking to inverted yoga, can help you find your personal Goldilocks zone for optimal health.

This conversation will change how you think about your body, your mind, and the invisible forces pulling on both.

0:13.6	I think about our psychology and what do we do as humans. We are trying to find patterns in chaos.
0:24.7	We are surrounded by entropy, by a world that's trying to pull us apart, both physically, emotionally, and in many other domains. And what we do as humans
0:32.4	is we make sense of the world, the physical input into our bodies, which is part of what this new book is about,
0:38.7	the emotional inputs, and how do we create a coherent narrative in our mind's eye that allows
0:44.0	us to find patterns that allow us to survive and thrive? And behavioral economics is a set of tools
0:49.6	to do that efficiently, but psychologically that's what we're doing, and that's what AI is starting to teach us in terms of how we go about doing that.
