We think it would be easier to just ask!! LOL!
Scientists have come up with a wack new way to determine how old someone is (within 5 years), just by examining their saliva.
The benefit to this test is that it could help identify how old crime scene suspects are, as well as determine people’s true biological age.
Said Dr. Eric Vilain, head researcher for the study:
"Our approach supplies one answer to the enduring quest for reliable markers of aging. With just a saliva sample, we can accurately predict a person's age without knowing anything else about them. While genes partly shape how our body ages, environmental influences also can change our DNA as we age. Methylation patterns shift as we grow older and contribute to aging-related disease.”
Science is awesome! And gross! LOL!
