The author explains a "program for death" built into the hypothalamus that causes death by hormone decline. The major causes of death such as heart disease, cancer, dementia, strokes and more, are all linked to hormone decline. There is a messenger produced in the hypothalamus that regulates your precious hormones downward, until the body succumbs to disease and can no longer survive. Inhibiting this messenger results in substantially higher hormone levels and greatly improved vitality and health. Hormone replacement therapy (HRT) is not needed. This book is essentially a blueprint for inhibiting that messenger, which results in optimal hormone levels and a much longer lifespan. The author presents his case, backed by references to over 40 clinical studies, and argues that the human body can live many hundreds of years if the hormones don't decline. Inhibiting this messenger, to avoid hormone decline is quite easy to do. The body is quite capable of producing, regulating and balancing it's own hormones at high levels, once you disable the program for death. Essentially, this book is about living athletically for several hundred years or maybe beyond, using a simple strategy that can be applied right now.
