A new JAMA study shows that those who sit a lot at work or home face a higher dementia risk than folks who sit less. This rings true for even regular exercisers. The study looked at nearly 50,000 people aged 60 and up. Dr. Andrew Budson from Boston University, not part of the study, confirms it suggests sitting long hours raises dementia risk. In essence: being active isn’t just about gym time; daily habits matter too. (Sources: washingtonpost. com, jamanetwork. com)
