Study: Excessive Sitting Cuts Life Expectancy by Two Years

Over the past few years, health experts have warned that spending an excessive amount of time sitting—regardless of whether one gets sufficient exercise or not—can kill. Now, a study released Monday puts a number on it: two years. An analysis of five large-scale studies following about 2 million people in several different countries found that the life expectancies of people who said they spent more than three hours a day sitting were two years less than people who spent less than three hours sitting daily.
