This correlates with previous studies that found that human aging accelerated around the ages of 44 and the early 60s. As soon as we’re born, we start aging, but scientists are quickly learning that not all aging is exactly the same. blood vessels) experience this aging faster than others, and the scientists also identified the proteins responsible for this accelerated process. about this new study, Snyder says that the findings largely align with his own scientific conclusions. “Together, our findings lay the groundwork for a systems-level understanding of human aging through the lens of proteins,” the authors write.
