Now is a great time to start a regular exercise program. In a 10-year study, researchers followed 654,827 people and tracked their exercise habits. Researchers found that the life-expectancy of participants increased as exercise time increased. People who walked 75 minutes each week lived 1.8 years longer, those who walked 30 minutes per day lived 3.4 years longer, and those who walked 1 hour per day lived 4.2 years longer.
