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.
