Biochemistry of Aging

Elsersawi sets out to survey the full landscape of aging science — DNA damage, oxidative stress, insulin signaling, NAD+ metabolism, and more — through an engineer's systems-thinking lens, and as an introductory overview for curious non-specialists it covers a lot of ground in one volume. Readers with some science background who want a broad map of longevity research before diving into more targeted sources will find the survey approach useful. The honest caveats here are significant, though: this is a self-published AuthorHouse title with essentially no critical reception and no peer review, and the author's primary training is in electrical engineering rather than biology or medicine. That doesn't make every claim wrong, but it means the book should be treated as a starting point for curiosity, not a reliable reference. Approach with appropriate skepticism.
