In this episode of the Primal Shift podcast, I sit down with Dr. Rob Carter, an integrative physiologist who has spent 25 years studying what happens to human beings under pressure. His new book, The Convenience Trap, makes the case that modern life has quietly outsourced our navigation, memory, attention, and physical competence — leaving most adults measurably less capable than they were built to be. I like that argument, which is exactly why I pushed on it. "Modern life is making us weak" feels so obviously true that almost nobody checks whether the science holds up.
We talk about the heat shock proteins behind sauna and heat adaptation, why hormetic stress builds resilience, and where the dose-response curve turns against you. Rob explains what the GPS research actually shows versus what gets blamed on it, why the average person can now recall fewer than four phone numbers, and how hydration advice went wrong in both directions — including the risk of hyponatremia. He also walks through the ALIVE framework from the book and makes the case that capability loss in adults is reversible. I share why I stopped using GPS and what came back when I did.
About Dr. Rob Carter:
Dr. Rob Carter is an integrative physiologist and four-time Taekwondo World Champion who has spent 25 years studying what happens to human beings under pressure, with a PhD in medical physiology, postdoctoral training at Harvard School of Public Health, and over 100 peer-reviewed papers on human performance and stress. His new book The Convenience Trap, co-written with his wife Dr. Kirti Salwe Carter, argues that modern life has outsourced our navigation, memory, attention, and physical competence — leaving many adults measurably less capable than they were built to be.
