In the film The Substance, Demi Moore portrays a 50-year-old star who resorts to a black market drug for anti-aging, only to discover the grim consequences of trying to reverse time. Unlike the movie, real-life aging can’t be evaded, yet the emerging trend of biological age testing implies we may manage how our bodies age.
Biological age differs from chronological age, reflecting overall health status based on body function compared to typical metrics for one’s age, as highlighted by James White, assistant professor at Duke University. This measurement utilizes algorithms and various biomarkers. Studies, including those by researcher Austin Argentieri, reveal that the disparity between biological and chronological age can predict disease risks.
While biological age tests are available from multiple companies, skepticism exists among researchers regarding their practical value. Critics like Argentieri suggest that simply knowing biological age lacks actionable health insights unless linked to disease risks. Others, such as Nikolina Lauc, emphasize the importance of consultation for interpreting test results and making lifestyle modifications.
Despite the fascination with biological age, experts warn about the limitations and advise caution in altering lifestyle based solely on test outcomes, as many interested individuals are already health-conscious. Ultimately, the pursuit of a ‘fountain of youth’ continues to captivate the public imagination, yet the underlying science remains complex.
