We talk with Harriet Brown, author of How Science, History, and Culture Drive Our Obsession with Weight–and What We Can Do About It (Da Capo Press, March 2015). Brown argues that focusing on weight as a measure of health is misguided and dangerous. Mark Hay, contributing editor to Modern Notion, joins us in the studio to tell the story of a Muslim prince enslaved in the American South. Plus, we hear stories of a family matzo company leaving the Lower East Side of New York and people who make their own space gear.
