Elderly women who sit for more than 10 hours a day with low physical activity have cells that are biologically older than their chronological age by eight years compared to women who are less sedentary, research shows. As a cell ages, its telomeres naturally shorten and fray, but health and lifestyle factors, such as obesity and smoking, may accelerate that process. Shortened telomeres are associated with cardiovascular disease, diabetes and major cancers.
