Today’s Seattle Timessummarizes the findings of a long-term study of how exercise improves health:

People who engaged in moderate activity—the equivalent of walking for 30 minutes a day for five days a week—lived about 1.3 to 1.5 years longer than those who were less active. Those who took on more intense exercise—the equivalent of running half an hour a day for five days every week—extended their lives by about 3.5 to 3.7 years, the researchers found.

In other words, sloth kills, and even moderate exercise can lead to a longer, healthier life.  Which is something to keep in mind next time you’re in the market for a place to live—choosing a home where it’s as convenient to walk to the store as to drive could actually save your life.
