## Resource

When Vance Crowe learned he needed half his thyroid removed, it sparked a deep question: what does it mean when your body's clock gets disrupted? In this candid and wide-ranging conversation, Vance brings on geneticist and light researcher Kate Crosby — someone he talks to almost daily — to explore the science behind the body's hidden timekeepers. They dig into how the thyroid regulates hormones and why losing it might put you on "synthetic time," why vitamin D and magnesium are so tightly linked, how intense exercise can unlock forgotten memories, and the surprising ways your ancestral latitude shapes everything from your seasonal diet to your fertility. The conversation takes unexpected turns into sunlight exposure, skin hardening, the Protestant vs. Catholic divide mapped onto geography, and whether modern life has knocked our biological clocks permanently off course. This is the kind of conversation Vance wants his daughters to hear — honest, curious, and willing to follow ideas wherever they lead. Guest: Kate Crosby is a geneticist and researcher specializing in light biology and light recipes for plant growth and human health. Articulate.Ventures/IBC LegacyInterviews.com
