“Individuals are aging at different rates as well as potentially through different biological mechanisms,” or ageotypes, the Stanford scientists wrote. “Of course the whole body ages,” said biologist Michael Snyder, who led the study. “But in a given individual, some systems age faster or slower than others.
What is psychological aging?
Description. Psychological age is how old one feels, acts, and behaves, and is thus not necessarily equal to chronological age, which is age since birth [1].
