Because medicine today is changing the lives of many older people, the desire to take the next step—to live as long as we want—has fueled a technological race in search of an elixir of life. As technological progress accelerates, making people immortal becomes more plausible. However, this progress also attracts pseudo-scientists, tech visionaries, scammers, and religious fanatics who seek personal gain from the race to immortality. Peter Ward’s book “The Cost of Immortality” is a detailed, carefully researched study of the current state of the fight for immortality. It attempts to separate scientists from fraudsters and takes you into the eccentric world of startups, research institutions, and billionaires—to find out what immortality will cost.
