Jeff Cavaliere tells Huberman that pain often comes from above or below the spot that hurts, Stuart McGill assesses back pain by provoking it and then removing the cause, and Huberman's back protocol explains sciatica and referred pain.

Andrew Huberman's immune episodes describe how the nervous and immune systems signal each other, with tools from sauna to cyclic hyperventilation and its E. coli study, Max Krummel describes memories that can recall immune states, and Huberman's pain episodes cover Wim Hof breathing, the stress response and inflammation. It suggests that part of immune defense can be steered through the nervous system.

Rhonda Patrick, Stacy Sims, William Li, Shawn Stevenson, Mary Claire Haver and Robert Lustig each separate the deep fat around the organs from the fat under the skin, and several explain how to spot it, from the idea of being skinny fat to the three fat depots, and how to bring it down. Knowing which fat is which changes what a reader tracks and explains why the scale alone can mislead.

Chris Duffin talks with Lex Fridman about feet, Antonio Brown credits foot exercises with keeping him elite, Huberman's back protocol includes toe spreading and the feet as distant stabilizers, and Stuart McMillan explains gait patterns and foot strike. Feet are the body's contact with the ground, and these sources treat them as something to train rather than only to put in shoes.

Mel Robbins and Tracey report a study of three seconds of eccentric exercise, Stuart McMillan ties eccentric strength to striding and aging, and Pavel Tsatsouline compares concentric, eccentric and isometric work.
