Discussing "The Science of Radical Life Extension" with TED Books author David Ewing Duncan

Continuing with our series of TED Book Chats.... How long do you want to live, and why?

For the next two weeks, we'll be discussing David Ewing Duncan's new eBook, "When I'm 164", on the science of radical life extension. Duncan surveys the increasingly legitimate science — from genetics and regeneration to machine solutions — and considers the pluses and minuses of living to age 164, or beyond. We'll look at everything from the impact of extended life on cities, services, and the cost of living as well as what happens to love, curiosity, and general health.

The book is available for Kindle, Nook, and iOS devices (which have a great new custom TED Books app):

Kindle copy: http://www.amazon.com/dp/B008XB16ME/
iOS app: http://itunes.apple.com/us/app/ted-books/id511071050?mt=8

The New York Times also published an excerpt this week, you can read it here: http://www.nytimes.com/2012/08/26/sunday-review/how-long-do-you-want-to-live.html

Finally, author David Ewing Duncan will be joining us for a live Q&A at 4pm EDT on September 11th!

Looking forward to our discussion!

  • Sep 11 2012: Hi David, I saw your article in the NYT a few weeks ago. Did most people really die around age 50 in 1900? Or was the average skewed by a higher percentage of infant/early childhood deaths? Did adults expect to live to about 50, or was it assumed that you'd make it closer to 60 or 70 once you reached adulthood? Thanks.

      Sep 11 2012: Infant mortality was much higher in 1900 and before, so this definitely dragged down the average. But even if you lived to 10 years old your life expectancy in 1900 was 58 years old - if you lived to 20, it was 62 (both for white males - slightly higher for women). Stats still work this way today - the longer the live, th longer your life expectancy (up to a certain point!) So we have added some years overall. What's really dramatic is how many more people are surviving to live a longer time. here is a chart of life expectancies since 1850: http://www.infoplease.com/ipa/A0005140.html
