Lack of exercise kills as many people as smoking does! Find out how much you should exercise to stay healthy

Everyone's always advised to get some exercise, and now, it just might save your life one day. Researchers have found that a lack of it is tied to heart disease, diabetes, and certain types of cancer. It causes nearly a tenth of the deaths worldwide, the same amount as how many people die from smoking!

Nearly a third of adults don't get the recommended amount of exercise. Despite this, measures haven't been taken to try to promote it more, though it's been found that even something as simple as improving street lighting can boost activity.

How much exercise is enough to prevent disease? Experts say that a brisk, half-hour walk five times a week is enough to help prevent many of the diseases than can be caused by inactivity.
