Every hour of TV viewing increases your chances of an early death, according to a new study by Baker IDI Heart and Diabetes Institute in Melbourne, Australia. Every one-hour program you sit through raises your odds for dying from heart attack or stroke by 18 percent, from cancer by 9 percent, and from other health problems by 11 percent, the researchers found. Although excessive TV viewing has been previously linked to health issues, this study is the first to tie the popular past-time to actual death rates.
