In "The Scientific Conquest of Death
" written by the Immortality Institute they surmize that immortality will become an eventuality and a reality not some fictional sci-fi fanboy wetdream.
The book is divided into two areas. The first being the Scientific Essays from well-known authors like Ray Kurzweil and Aubrey De Grey which outline potential solutions to the problem of aging, and why it will eventually happen. Also they speculate on when it may occur.
The second half is about the Perspectives or philosophic arguments why becoming immortal is a worthy goal.
Overall its a great introduction to radical life extension ideas and philosophies. My only criticism of the book is that I would have preferred it to be a little more technical and less general but I guess its trying to get the word out to as broad an audience as possible which is definitely a worthy goal.
A second book I would recommend is Aubrey De Grey's "Ending Aging: The Rejuvenation Breakthroughs That Could Reverse Human Aging in Our Lifetime
" which goes a little more into the technical side which I personally love but may put some lay-people to sleep.
First by breaking down exactly what happens to your body when its aging and the processes behind it and then by comparing our body to a machine in which parts can systematically can be repaired piece by piece as damage is accumulated throughout our its and our lives.
Lastly he goes into his recommendations for how the R&D community could and should go about redirecting its resources by solving the problem of age related diseases.
In all its easily one of my top 3 books I've read over the last few years.
