Barash, The Wall Street Journal "It has my vote for science book of the year.” —Parul Sehgal, The New York Times "Immensely readable, often hilarious...Hands-down one of the best books I’ve read in years. I loved it." —Dina Temple-Raston, The Washington Post From the bestselling author of A Primate's Memoir and Determined: A Science of Life Without Free Will comes a landmark, genre-defining examination of human behavior and an answer to the question: Why do we do the things we do? Behave is one of the most dazzling tours d’horizon of the science of human behavior ever attempted. Moving across a range of disciplines, Sapolsky—a neuroscientist and primatologist—uncovers the hidden story of our actions. Undertaking some of our thorniest questions relating to tribalism and xenophobia, hierarchy and competition, and war and peace, Behave is a towering achievement—a majestic synthesis of cutting-edge research and a heroic exploration of why we ultimately do the things we do . . . for good and for ill.

GLP-1s and the ‘Wild West’ of Wellness

Here’s a shocking number: One out of eight American adults is taking a GLP-1, like Ozempic or Zepbound, according to a KFF poll. GLP-1s are the biggest pharmaceutical story since antidepressants. But there’s still so much we don’t know. “We’re only at the beginning of what’s been called this Ozempic era,” the journalist Julia Belluz told me. “I think we’re really just at the beginning of discovering the benefits and the harms of these drugs.” These discoveries begin in the research but are also expanding into how we think about our punishing beauty standards and the blurry lines between illness and wellness. Belluz is a contributing Opinion writer and the author, with Kevin Hall, of “Food Intelligence.” She’s one of the best health and science reporters I know and has been reporting on GLP-1s for years. In this conversation, Belluz takes me through what we know — and don’t know — about GLP-1s, their unexpected uses, how they are clashing with a culture obsessed with thinness and looksmaxxing, and whether everyone should be on them.
