How Brain Cells Can Predict Your Age

As we get older, our brain cells show changes, and now a new study finds that certain changes happen so reliably that by themselves they can reveal a person's age. In the study, researchers analyzed brain tissue samples from 480 people who died between the ages 16 and 106. They found that, with age, certain types of brain cells called glial cells showed a shift in their gene expression patterns in certain regions of the brain.
