According to Betty Greaver, RN, LMT, it’s a common myth that aging means a person gains weight, has chronic pain and can't continue living a productive life. Rather, Greaver says, and research shows, there are simple lifestyle changes that people can make in order to remain active and have the capacity to enjoy life to its fullest, no matter what a person’s age. Greaver says that it’s important to pay attention to your health in the middle years so that you have optimum health in your later years and she shares three lifestyle changes that are important in establishing and maintaining a healthy lifestyle.
