A new study in the Archives of Internal Medicine finds that those who are most fit at midlife suffer the fewest chronic diseases after the age of 65. These included: heart disease, stroke, diabetes, lung disease and Alzheimer's disease.
Researchers say this shows that being fit is not just delaying the inevitable, but it is actually lowering the onset of chronic disease in the final years of life, so putting time in exercising now could really pay off in your senior years.
