Happy New Year! For many of us, a new year brings a renewed sense of motivation when it comes to health. Earlier this year, Russ sat down to speak with Jonathan Long, a Stanford biochemist who studies the chemicals produced during exercise. The conversation was one of our most popular during 2024 and today we’re re-sharing it. As many of us look to create healthy habits in 2025, we hope you’ll tune in to hear the exciting research Professor Long is doing to better understand the deep chemical connections between diet, exercise, and human health.
Have a question for Russ? Send it our way in writing or via voice memo, and it might be featured on an upcoming episode. Please introduce yourself, let us know where you're listening from, and share your quest. You can send questions to thefutureofeverything@stanford.edu.
