A new study using blood tests and Artificial Intelligence (AI) have found smoking to accelerate ageing. Baltimore based AI solutions company Insilico Medicine carried out the research based on blood profiles of 149 000 adults, of whom 33% (49 000) reported to be smokers. The researchers combined an age-prediction model using a technique called deep learning and various biochemical markers among the participants. These included levels of blood sugar, fasting glucose, iron stores and urea, a waste product excreted in urine.
The findings suggest smokers in their twenties to be biologically up to two decades older. Smokers between ages of 31-40 were predicted to be about a decade older than their age.
