Understanding Biological Age vs. Chronological Age
Biological age, determined by the health of each individual cell, differs from chronological age, which is simply the number of birthdays celebrated. One might be 60 by years yet have a biological age of 45 or even 75, which has significant implications on overall health and risk for diseases such as Alzheimer's and diabetes. The concept of 'juventology' introduced by Dr. Walter Longo emphasizes assessing one's youth span rather than just aging chronologically, framing aging not merely in years but in functional capacity. This perspective illustrates the importance of focusing on biological age to better understand health risks and longevity.
