Conversations about wellness and our bodies usually don’t focus on what makes all movement possible – our muscles. But these parts of us are more complex than we give them credit for and tied to our overall health in nuanced ways. How we think about strength and muscle also differs based on our gender, upbringing and experience of society. In her latest book, “On Muscle: The Stuff That Moves Us and Why It Matters,” journalist Bonnie Tsui explores how muscles really work, and what doctors and scientists are learning about the importance of strength training and muscle health. In this program from Aspen Ideas Health, Tsui explains to CNN medical journalist Elizabeth Cohen how her curiosity about muscles led her into deep research, anatomy lab visits and reflection on culture, herself and her family.

Writer Pico Iyer stumbled into a lifelong practice of periodic retreat and reflection after he lost nearly everything in a 1990 wildfire that burned his family’s house down. A friend suggested that he recuperate at a Benedictine monastery near Big Sur, California, and the calm he found there was life-altering. He began returning to the oceanside hermitage regularly, and slowing down became a fundamental part of his life and productive career. In this talk from the 2025 Aspen Ideas Festival, Iyer shares what those times of silence have given him, and how he’s learned to navigate tumult while always coming back to peace. Iyer’s latest book is “Aflame: Learning from Silence,” and he’s also the author of “The Half Known Life” and “The Art of Stillness,” among several other books and many essays.
