Exercise is the key to staying younger
Recent studies show that exercise helps delay aging. In long term studies that compare those who exercise to those who do not, researchers found as much as a 9 year biological difference between the two groups. That is at the cellular level the exercisers are about 9 years younger than the non exercisers.
To derive maximum benefit from exercise, you must engage in activities that get the heart pumping, like biking, aerobics, swimming, etc. You don’t have to do a full hour or more at a time, but can break it up in 15 minute chunks. Ideally, you want to spend at least 3 hours a week exercising.
