(From the Baltimore Sun). Life expectancy has been rising with the advance of medical technology throughout the 20th century. Conservative gerontologists like Jay Olshansky - who seem to believe that we cannot address the underlying aging process - believe this rate of increase will slow and stop. Forward looking scientists like Aubrey de Grey are working to build a far better future, however. Aging is simply damage to the body, and this can in principle be repaired - all we have to do is to direct sufficient resources to solving this problem. Progress in regenerative medicine is a good start, but there is far more work to be done on medical science, activism and education.
