Although women live, on average, five years longer than men, they disproportionately suffer from ageing-related illnesses: from dementia and osteoporosis to autoimmune disease and cardiovascular decline. Yet the vast majority of longevity science is written by, tested on, and optimized for men. The Longevity Curve is Dr. Killen's answer to this imbalance - a visionary, evidence-based roadmap built specifically for women's biology. At the heart of her method is Hormone Optimization Therapy (HOT) - a powerful yet often misunderstood tool to address the estrogen collapse of menopause and its downstream impact on ageing.

But this book goes far beyond hormones. The Longevity Curve introduces a full-body framework for transformation-delivering a comprehensive, science-driven, and deeply human guide to extending healthspan, not just lifespan. It is the first book to directly connect ovarian ageing to systemic decline, then offer a clear, strategic blueprint for reversing it. Rather than focusing on symptom management, Dr. Killen reframes midlife as a powerful second biological chapter-one fuelled by strategy, agency, and reconnection.

The Longevity Curve is a bold call to action. It empowers women to reclaim their energy, vitality, and clarity-on their own terms.
