You Have Four Ages

The video explores the concept of biological age, which differs from chronological age, as different body parts age at different rates. It discusses how biomarkers are used to determine biological ages and highlights a 2020 study that advanced understanding in this area. The study identified biomarkers for various organ systems and showed that different systems age at different rates. Factors like genes and lifestyle influence aging, and interventions can potentially alter biological ages. The video also mentions ongoing research into heterogeneous aging, suggesting that age is not a single number but multiple, depending on various factors.
