Why it’s harder to concentrate as we get older (Daily Mail UK)

Daily Mail (UK) cited research co-authored by Mara Mather of the USC Leonard Davis School on how it gets harder to focus without being distracted past the age of 55, particularly when under stress, because of the way our brains change over time. “Deciphering exactly how these changes in the brain occur as we age could one day help us uncover how to protect the brain from cognitive decline,” said Mather.
