Chances are you’re slumped over in your chair reading this — a constant in our modern world. Historian Beth Linker is the Samuel H. Preston Endowed Term Professor in the Social Sciences in the Department of History and Sociology of Science at the University of Pennsylvania. She joins host Krys Boyd to discuss how posture ignited public health panics and race hierarchies of previous generations and why we should examine our previous beliefs to better understand fitness today. Her book is “Slouch: Posture Panic in Modern America.”
