Saliva is used to estimate person’s age, its interesting! Yes, in one of the research at University of California in Los Angeles, Scientist has discovered a new way to calculate the age of person using saliva. The research was carried out for three years and during which around 130 samples were studied and found that with the calculation of chemical changes of DNA of saliva one can accurately estimate age of the person.
After successful completion of this research for 3 years, Dr. Eric Vilain who is a renowned doctor and researcher at the UCLA centre of medicine announced that they are able to predict the age of person with (max 3-5 years of error) without knowing the sample or person under test. These scientists believe that this new technique of understanding the age of person from the study of DNA of saliva will help a lot in forensic investigations and other research fields.

Even the traces of saliva left behind on the field or any other source can help a lot to direct the investigation and to solve the cases. Also the calculation of persons DNA age will help doctors and medical field to determine if the patient’s body to any treatment or phase is having any effect on aging (or on changes in DNA of saliva). This will also determine patient body is aging is faster or slower.

New research in this field is being done in which comparison of DNA of saliva to that of DNA of blood and other samples are done.This knowledge is rapid being used in medical and other fields for wellbeing of humans.
