What if getting old isn't a done deal? The morning after her mother died at 103, Kristin van Tilburg looked in the mirror and saw her own face, aged ten years overnight. The evidence was right there in the glass: her thoughts and feelings had rewritten her biology in a single night. That moment cracked open the question that became this book. What if aging isn't inevitable biology, but an inherited default program? What if it can be interrupted? The title isn't a rejection of her mother. It's a refusal of the cultural script her mother lived under, a script most women live under still: the one that says aging is a slow disappearance, that decline is inevitable, that vitality has a shelf life. Drawing on nearly five decades of transformation work, her MSW, graduate research in a behavior genetics lab, and emerging research in heart coherence, cellular senescence, biofield science, and the gut-brain connection, Not My Mother offers a different kind of longevity book. It doesn't offer diet protocols, biohacks, or supplement stacks. Instead it names something deeper: the doubt operating system, installed before language, that runs underneath the body's aging process.

Across fifteen chapters, van Tilburg lays out the seven hijackers that quietly age the body whose voices she's spent decades catching in her own life. They whisper it's all downhill after fifty, don't be selfish, you're running out of time. Each chapter weaves her own stories alongside the science, then names the shifts that interrupt them: doubt to trust, fear to love, disconnection to connection. Every chapter closes with a "Youthing" Practice that takes minutes, not hours. Written for women over fifty who have done the inner work and arrived at the place where knowing isn't enough anymore, this is a book about choosing radical aliveness as a lifestyle, in a body, every day. The flame at the center of you was never lost, only covered over. The mirror that opens this book closes it too, with a more youthful face looking back. You can be radically alive.

You are not your mother.
