PopSci article on immortality theorist Aubrey de Grey

De Grey contends that we know enough to intelligently map out a program of anti-aging intervention research such that sometime in the next 100 years, and quite possibly much sooner, the average human life span may be 5,000 years, a figure brought short of outright immortality by the small number of people who will die from non-age-related diseases and everybody else who, given the boggling amount of time available to them on the planet, will eventually do something unlucky or stupid like walk in front of a moving rocket car.
