Regardless of your age, you can make a number of important changes in your current lifestyle. That will help you feel better physically and mentally. {{U}}Recently researchers have found that, even in late adulthood, exercise, strength training with weights, and rational diet can help elderly individuals significantly improve their health and add happiness to their life{{/U}}. {{U}}We know much more about preventive health today than our parents and grandparents did in the past.
