This article on CNN.com, posted on November 30th, immediately caught my eye.
Your chronological age is fairly self-explanatory – It’s based on your birthday.
Your biological age is a bit more complicated – It’s called someone’s phenotypic age.
Phenotypic: Relating to the observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Remember biology class?
Long story short: Your biological age determines health and lifespan.
Morgan Levine, a professor and researcher at Yale Medical School, worked with her team to identify nine biomarkers in a simple blood test. Some of these biomarkers include blood sugar, kidney and liver measures, and immune and inflammatory measures.
The bottom line: People who have a lower biological age than their chronological age have a lower mortality risk.
What’s interesting about Levine and her team’s research is that your biological age is not permanent. It can be adjusted. Meaning, changing things like lifestyle, diet, exercise, and sleep habits can lower one’s mortality risk and improve one’s biological age.
Currently, Levine is working to provide access to the algorithm online so that anyone can calculate their biological age, and take further steps to improve it.
