You can find coverage of TEDMED 2009 back in the archives here and at the Longevity Meme:
Also before lunch was the science of aging pair up with Aubrey de Grey, CSO of the SENS Foundation, and David Sinclair, professor at Harvard Medical School. If you've not heard of these gentlemen before, both view aging as a disease but both are approaching aging in very different ways. Aubrey spoke first and has a more futuristic view of aging. His mantra is that aging is metabolism caused cellular damage that leads to organism pathology, and the human body, just like cars, can be made to run longer with adequate maintenance and repair. He views age related problems as belonging to seven types and in order to tackle aging, all seven cellular and molecular problems need to be cured. Aubrey also coined the idea of a Longevity Escape Velocity (LEV), which is the point of life span where progress in aging science is occurring faster than the degradation of the body itself. He believes that if someone is able to live to 150 years old, then by that point the progress in the ability to keep them alive will be faster than their rate of death, thus they will live into their 1000s.
