Christian Drapeau - A Neuroscientist on the Longevity Marker Nobody Is Measuring

Something changed after 40. Recovery takes longer, energy dips, and the effort that used to work stopped working. You were told it's just aging. Neurophysiologist Christian Drapeau makes the case that it's something else entirely: the decline of your body's own repair system. In this first episode of The Science of Vitality After 40, a four-part series with Christian Drapeau, host Eric Malzone explores the system almost no one talks about. Christian wrote the first paper proposing that our stem cells function as the body's repair system back in 2001, and here he explains what that system is, why it declines so early (by your early 30s you circulate a fraction of what you had at birth), and why the shift lands hardest on women in their 40s. In this episode: What the repair system is, and why it works like a second immune system Why medicine treats the body's ability to heal as a "black hole" The steep, early decline in circulating stem cells and what drives it Why estrogen loss creates a "double whammy" for women at midlife Why weight-bearing exercise keeps emerging as the one clear lever What your circulating stem cell count may predict about how you age Christian Drapeau is a neurophysiologist, a pioneer of stem cell mobilization, Founder and Chief Science Officer at STEMREGEN, and author of the bestselling Cracking the Stem Cell Code.
