Your gut bacteria may reveal how fast your brain is aging

A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could ev
