Exercise equals longevity

From a study reported in the Guardian:

Yates estimates that a 70-year-old man has a 54% chance of reaching the age of 90 if he does not smoke or have diabetes, has healthy weight and blood pressure, and exercises. But cutting out exercise and becoming more sedentary reduces the chances of reaching 90 to 44%. The chances dropped further with high blood pressure (36%), obesity (26%) and smoking (22%). Any three of these cut the chances of living to 90 to 14%.
