According to a study published in the Official Journal of the American College of Sports Medicine the least-fit segment of the population has twice the mortality risk of even those who are just a bit more in shape.
A research team from Stanford University, performed exercise tests and followed more than 4,300 subjects from 1986-2006, none had a history of heart disease.
Fitness and physical activity levels were measured using tradmill tests and questionaires and mortality rates tracked during the 20-year study.
Results showed that the least-fit had twice the mortality rate compared to the second least-fit group and more than 4 times the rate of the most fit group.
So if you're in this group then it may be time to be more active in order to reduce the risk of dying earlier then those who are a bit more active.
