Aging is a natural process, but how do we differentiate between normal changes and accelerated aging? What are the critical periods in life when significant health changes occur? Why do they happen, and how to navigate them for better aging outcomes? We spoke with Michael Snyder, PhD, professor in genetics at Stanford University, about groundbreaking research into the health profiles of people in their 40s and 60s, uncovering key factors in aging, and practical lifestyle modifications to promote long-term wellness.
