An international study appears to have created a test that can determine the biological age of a patient’s body. The research – undertaken by King’s College London (KCL), the Karolinska Institutet in Sweden, and Duke University in the US – could have a broad range of applications, including improving screening techniques for age-related diseases such as Alzheimer’s, allowing doctors to begin treatment earlier in the process.
Before delving into the importance of the research, we have to understand the difference between chronological age and biological age. Your chronological age is your age in years, days and minutes from the moment you were born. Whilst all people age chronologically at the same rate, our bodies run on a separate biological clock, meaning that the bodies of two people at the chronological age of say 50, could have significantly disparate biological ages.
