A slow walking pace might triple your risk of cardiovascular death.

The speed at which you walk may dramatically influence your risk of dying from cardiovascular disease according to a 5 year French study of well-functioning men and women over 65 years of age. Those in the lowest third of walking speed had a threefold (2.92 odds ratio) increased risk of cardiovascular death compared to the highest third of walking speed. Interestingly, walking speed made no difference in cancer mortality risk. These differences held true after controlling for potentially confounding factors, although reasons for these observations are not understood fully.

PositiveTip: Pick up your pace of walking (as fast as comfortable without running) -- it could significantly extend your life.
