How Coffee Changed the World
Coffee was once put on trial. In 1511, the governor of Mecca brought it before the city's religious scholars to settle a single question: Is this drink dangerous? They let it go, and coffee spent the next five centuries changing where people gathered, what they talked about, and how they traded. This episode of 1440 Explores follows it from a wild Ethiopian shrub to the 2 billion cups the world drinks every day, by way of Sufi prayer halls in Yemen, the coffeehouses of the Ottoman Empire, the London coffee shop that became the London Stock Exchange, and the Brazilian plantations that ran on enslaved labor. Host Sony Kassam is joined by Professor Jonathan Morris of the University of Hertfordshire, who explains what roasting actually does to a bean and why caffeine is a suppressant rather than the stimulant everyone assumes.

Why We Lose Muscle–And How to Keep It
Strength training prevents frailty as we age. Wards off cognitive decline. Improves glucose control, and more. But what is actually happening inside our bodies when we lift weights? And why is everyone suddenly talking about getting strong? In this episode, 1440 Health & Medicine Editor Dina Fine Maron digs into the science and surprising history of getting strong. She explores how resistance training complements aerobic exercises like running, its role in the era of GLP-1s, and how attitudes toward lifting have evolved–from ancient Olympian might to circus spectacle to fears that big muscles make athletes stiff and slow. Guests: Daniel Lieberman, a human evolutionary biologist at Harvard University. Amanda Paluch, a kinesiologist who studies physical fitness at UMass Amherst.
