It is described at amazon.com as to be published in February, but this is incorrect -- it is available now. It covers most aspects of mitochondria and free radicals as they relate to aging, including extensive background information (enough, I hope, that the scientifically-minded non-biologist will be able to cope with it). There is also detailed discussion of some perhaps-imminently-feasible life-extension interventions.
I haven't read it yet, but hope to do so soon.
