Specialists at Yale University have learned to determine the probable life expectancy of a person by analyzing his blood. The method is based on the establishment of “phenotypic age”. The phenotype refers to the signs of an organism that appear in the process of its development.
Blood pathologists are tested on nine biomarkers. Thus, it was much more accurate to predict the life expectancy than based on individual biomarkers or the chronological age of a person.
Especially this method is useful for determining people whose aging process is accelerated in comparison with normal indices. This places them at an increased risk of early death. Having passed the test, a person will be able to more carefully approach medical examinations and monitor their health.
Experts say that a 65-year-old man can physiologically approach 70 years – in this case, he will have a 70-year, not 65-year risk of death. In the study, scientists noticed that men usually grow older faster than women.
