Where life is going

Darwin asked how life began. This book asks where it is going — and whether its duration is fixed.

Three decades of operating gives you a particular view of the body. You see, directly and repeatedly, what tissue does when it is damaged, and what it does when it repairs. You see chaos — and you see creation. The two are not opposites; they are the same machinery, read in different directions.

That vantage point is where this book is written from. It takes the reader to the frontier of regenerative medicine, longevity science and human performance: the cellular and genetic mechanisms behind aging, and what stem cells, gene editing and emerging biotechnology mean for the span of a human life.

The question underneath it all is simple to ask and hard to answer: why do we age — and can the body's own repair systems be persuaded to hold the line?
