Scientists across the world, Ms. Arrison says, are working on engineering close to two dozen different human organs in the lab, including bladders, lungs and hearts. Progress is slow, and it might be decades before bioengineered organs are commonplace, but the trend-line is clear. A force behind the movement is the U.S. military, an eager funder of restorative and regenerative engineering. Dr. Robert Vandre, chairman of the Armed Services Biomedical Research Evaluation and Management Committee, thinks that "ultimately, we will be able to grow limbs" for wounded soldiers.
And if humans do begin living to 150, then what? If Medicare and Social Security are in trouble now, what happens when they must support multiple generations of retirees? In Ms. Arrison's mind, we'll be living healthy, productive working lives until very near the end. The more pressing concerns, for her, have to do with the strain on natural resources and the added pollution of a swelling world population.
