Feeling young could mean your brain is aging more slowly

(Frontiers) While some people are young at heart, others feel older than their age -- and a recent study finds that this 'subjective age' may reflect brain aging. Researchers found that elderly people who feel younger than their age had a younger estimated brain age, compared with those who felt their age, or older than their age. The study is the first to find a link between brain aging and subjective age.
