Do You Want to Live longer? Start Walking More and Sitting Less

Replacing one hour of sitting each day with walking can decrease the chance of early death among seniors by 12-14%. Researchers also note that swapping one hour of sitting each day with standing results in a 5% decrease in the risk of premature death. On average, people over the age of 70 spend around 65-80% of their waking time performing sedentary activities, so substituting some of this time with standing or light physical activity could have a positive impact on their overall health.
