For newborns in the U. Repeating this feat during the lifetimes of people alive today is unlikely. Most of the prior advances in life expectancy at birth reflect dramatic declines in mortality risks in childhood and early adult life.

Because the young can be saved only once and because these risks are now so close to zero, further improvements, even if they occurred, would have little effect on life expectancy. Even with precipitous declines in mortality at middle and older ages from those present today, life expectancy at birth is unlikely to exceed 90 years males and females combined in the 21st century without scientific advances that permit the modification of the fundamental processes of aging.

To exceed this limit, the underlying processes of aging that increase vulnerability to all the common causes of death will have to be modified. United States life tables, National Vital Statistics Reports. In Search of Methuselah: Estimating the upper limits to human longevity.
