Summary:
- The article discusses a study on "superagers" - people over the age of 80 who have the cognitive abilities of much younger individuals.
- Researchers found that superagers have thicker cortexes in certain brain regions, which may help protect them from the effects of Alzheimer's disease and other forms of dementia.
- The study suggests that maintaining an active lifestyle and challenging the brain as we age can help preserve cognitive function and delay the onset of age-related neurological decline.
