How long do you want to live? 80 years, 120 years, 150 years, or forever are possible answers to this question that bestselling science writer David Ewing Duncan, the author of Experimental Man, asked 30,000 people in his new TED e-book, "When I’m 164: The New Science of Radical Life Extension, and What Happens If It Succeeds".

While riffing on the Beatle's song "When I'm 164," the book surveys the increasingly legitimate science of radical life extension—from Healthy Living and Genetics to Regeneration and Machine Solutions—and considers the pluses and minuses of living to age 164, or beyond; everything from the impact on population and the cost of living to what happens to love, curiosity, and health. He shares classic stories and myths of people determined to defeat aging and death, and offers real-life tales of the techno-heroes and optimists who believe that technology can solve the "problem" of aging.
