Results of examination of national health data would appear to be indicating that rate of biological aging appears to be more delayed in Americans, especially men, which may extend lives, advancements in medicine have been cited as one possible reason for deceleration.

 While it may be true that currently you can’t turn back the clock on time, but it would appear as if it can be slowed down, as this study is suggestive that Americans are aging more slowly than they were 2 decades ago according to a study from University of Southern California and Yale University, who suggest that part of the gains in life expectancy may be due to a change in the rate of biological aging rather than keeping ailing people alive.
Deceleration of the aging whether through biomedical or environmental intervention would push timing of aging related disability and disease incidence to closer to end of life.
