Death rates in later life flatten out and suggest there may be no fixed limit on human longevity, countering some previous work.
A recent study in Italy has found mortality rates level off at around the age of 105 years. Although, they certainly spike prior to becoming a Centenarian, research shows remarkably that the human body can “settle in” to its aging form, and potentially live that way for a long time.
For the science of human longevity, this is another in an exciting paradigm of research currently exploding inside the scientific community.
It jibes with the Harvard mice study (Sinclair, David, professor in the Department of Genetics at Harvard Medical School and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School) and the replenishment of NAD+ (Nicotinamide Adenine Dinucleotide) in the cells through the precursor enzyme, NMN (Nicotinamide Mononucleotide).
NAD+ is an enzyme identified as essential to life and found to diminish in humans, and all living things for that matter, as they age. Sinclair’s research was successful in reversing the symptoms of aging and is ongoing.
The two separate, but very relatable studies, form the bedrock of longevity study and the implications of what a very long life might look like in the near future for humanity.
