Never too late to exercise

Exercise can help slash your risk for heart disease and diabetes no matter how late in life you start, say University of Western Ontario researchers. Investigators compared two groups of healthy but sedentary adults ages 55 to 75. One group began regular, supervised exercise, and the other stayed inactive. After 10 years, the exercisers grew fitter while the couch potatoes’ fitness declined. What’s more, those in the active group were less likely to develop metabolic syndrome, a collection of factors—high blood pressure; high cholesterol, triglyceride and blood sugar levels; and too much abdominal fat—that raises heart disease and diabetes risk.
