In this episode of MindTricks Radio, I spoke with Dr. Art Markman about the subjectivity of age and time—why we often feel younger than the number on our birth certificate, why time seems to speed up as we get older, and what psychology can tell us about making life feel fuller, longer, and more meaningful. We talk about the difference between chronological age and subjective age, the strange experience of looking in the mirror and seeing someone older than we feel inside, and how staying physically active, socially engaged, and open to new experiences can help people maintain a sense of vitality. Dr. Markman also explains why childhood and travel can feel so expansive, while routine-heavy adult years can seem to disappear in a blur. This was a lively, thoughtful, and surprisingly practical conversation about aging, memory, novelty, regret, and the importance of saying yes to life. Dr. Markman brings warmth, humor, and deep cognitive science expertise to a topic that touches everyone: how we experience the passing of time, and how we might live in a way that makes that time feel richer.
