HOW TO TELL A PERSON’S BRAIN AGE:

In recent years, scientists have plumbed the molecular depths of the body and surfaced with tell-tale biomarkers of aging, some of which extend to the brain. Now, researchers are harnessing another tool, neuroimaging, to measure the organ’s age, and using that to predict how long a person will live…

…Cole and his colleagues recently devised their own technique of predicting the biological age of people’s brains using a combination of machine learning and magnetic resonance imaging (MRI) scans.

As for determining if someone is brain dead, voting for Hillary is definitely a tell-tale marker.
