Some key quotes from the article:
"This work, in my opinion, is a conceptual breakthrough because it determines and separates the roles of fundamental factors in human longevity - the aging, defined as progressive loss of resilience, and age-related diseases, as "executors of death" following the loss of resilience. It explains why even most effective prevention and treatment of age-related diseases could only improve the average but not the maximal lifespan unless true antiaging therapies have been developed" - says prof. Andrei Gudkov, PhD, Sr. Vice President and Chair of Department of Cell Stress Biology at Roswell Park Comprehensive Cancer Center, a co-author of this work and a co-founder of Genome Protection, Inc., a biotech company that is focused on the development of antiaging therapies/.
"The investigation shows that recovery rate is an important signature of aging that can guide the development of drugs to slow the process and extend healthspan." - commented David Sinclair, Harvard Medical School professor of genetics.
And if it's something you can influence, resilience can be a determining factor.
It makes sense. The quicker the heart returns to resting heart rate after strenuous exercise as you age is one determining factor in how fit and healthy you are. It is probably the same for all the other body parts and organs.
