Couch Potatoes

A recent Australian study links time spent watching television with an increased rate of death. According to the study, people who said they watched TV for more than four hours a day were 80% more likely to die of cardiovascular disease than those who reported watching less than two hours of television a day. Professor Marc Hamilton, who studies Inactivity Physiology at Pennington Biomedical Research Center, in Baton Rouge, Louisiana, explains how a sedentary lifestyle takes a toll on your health.
