The decline of infections, starvation, heart attack, and stroke has allowed people to reach extreme old age-and ushered in disability, dementia, and degenerative disease, with profound consequences for the self and society. In chapters echoing Dante"s nine circles of hell, Dr. Guy Brown explores these vital issues at various levels, from the cell, to the whole body, to society and how all this new medical technology affects the meaning of death. He tracks the seismic shifts in the causes and character of death that are rocking medicine and reveals how technological innovations, such as cloning and electronic interfaces, hint at new modes of "survival" after death.
