Now we may be able to predict our life span with a simple blood test.
In a study published in Nature Communications last week, scientists from across Europe, UK, and Australia identified 14 biomarkers that can help us predict life span with reliable accuracy. As the biomarkers are lipid-based, this study shows that we may be close to devising a blood test for calculating a person’s life span. 
This could be useful in critical medical procedures in determining whether an elderly patient can withstand an aggressive invasive procedure or in clinical trials where a participant’s longevity is critical in ensuring the integrity of the sample size. These markers were found to be similar in men and women across different age groups.
