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: Mr. Duncan - I'm interested in stem cell research, and you mention it in your article. Do you think we're eventually going to be able to use stem cell regeneration to replace our own worn-out body parts as they fail? I'm imagining medical science that works like taking your car to the shop.

      Sep 11 2012: More and more scientists are saying that stem cells will one day be used to provide fresh cells to repair tissue damaged from disease, accidents, or aging, though in most cases this is many years away. However, scientists like Anthony Atala at Wake Forest have successfully grown human bladders and urethas that have worked in humans - though he cautions that these are simpler to "build" than a heart or liver; others say something as complex as the human brain will be very hard to repair. One huge boost in stem cell tech came just 5 years ago with the invention of "Induced Pluripotent Stem Cells" (biologists have such clunky names for things) - these are stem cells that are made using any cells in a person's body. IPS cells can then be used to make any cell in the body - which are perfect genetic match with the donor. IPS cells still need some serious work to be used for regeneration or transplantation, but the potential is there.
