Joe Rogan sets out his rule changes with Israel Adesanya, Jiří Procházka and Belal Muhammad (up kicks, referee stand-ups, better gloves, covered fingers, no cage), while Royce Gracie, Tank Abbott, Rico Verhoeven, John McCarthy, Justin Gaethje with Trevor Wittman, and Matt Serra's group debate gloves, eye pokes, kicks to the knee and rules that make no sense.

Insight | Performing versus being: what living as a version of yourself costs

Therapist Kier Gaines, hospice doctor Zach Bush, researcher Brené Brown and Mel Robbins each describe the gap between who a person is and the version they present, and say that keeping it up costs energy, confidence and, at the end, peace.
