Older adults that find themselves worrying on a regular basis could simply be expressing an element of their intelligence, according to a new study. A cohort of United States researchers claim that the human capacity to worry may have involved with intelligence as a "beneficial trait". It was identified that high intelligence and fretting correlate with brain activity measured by a depletion of the nutrient choline in white matter of the brain. Dr Coplan, researcher on the study, commented: "While excessive worry is generally seen as a negative trait and high intelligence as a positive one, worry may cause our species to avoid dangerous situations." Worry may also help to coerce people into taking chances, which has multiple benefits for the species as a whole, the researchers claim. Nonetheless, older adults experiencing feelings of continual anxiety and stress should take steps to relax. Exercise is a great way to get the brain to calm down. A healthy diet also promotes good cognitive function. Find the nearest Barchester care home.
