Researchers at King’s College London (and internationally) have developed techniques promising to accurately measure a person’s “biological age”. People of the same chronological age vary in their rates of “biological ageing” – sometimes by margins of up to 15 years, plus or minus – so an individual measure of biological age could be a more accurate prognostic measure.
The test under investigation involves examining the “ageing signature” in biomarkers of gene activity across 150 genes in the body’s cells. Such a test would potentially help predict when a person might die, and could help identify people at high-risk of dementia and other conditions; apparently largely independent of (or impervious to) various lifestyle interventions. Such a development would have serious implications for the future of medicine, pensions and insurance, particularly as it is not (yet) known to how to slow the biological ageing processes in question.
