I'm intrigued by this word: Biogerontology. A new book by 40 co-authors (The Future of Aging: Pathways to Human Life Extension)is purporting that human life can be extended through the therapeutic use of biogerontology (e.g., sirtuin-modulating pills, new concepts for attacking cardiovascular disease and cancer, mitochondrial rejuvenation, stem cell therapies and regeneration, tissue reconstruction, telomere maintenance, prevention of immunosenescence, extracellular rejuvenation, artificial DNA repair, and full deployment of nanotechnology). Interesting concepts. The book is a bit pricey so I doubt I'll purchase it, at least not right away, as some of these concepts are likely decades in the future. Interesting, however.
