Thanks as always for the links, Swen!

Aubrey de Grey's talk on human life extension is the Ted program I watched most often, probably somewhere around five times.

• German-language Wikipedia on de Grey
• English-language Wikipedia page for de Grey with dozens of links, including a full-length documentary about him, Do You Want To Live Forever?

(De Grey isn't excited about the "Live Forever" rhetoric but at this point accepts it as being almost inevitable if you want to disseminate an idea via mass media.)
