An hour of TV could shorten your life expectancy
On the heels of study revealing just 15 minutes of exercise a day can significantly extend your life, another batch of research suggests that watching too much TV could shorten it.
The news agency AFB reports that Australian scientists found that watching an average of six hours of television or videos a day can shorten your life by as much as five years.
The study focused on a group of 11,000 Australians who were at least 25 years old and checked the data against the country's mortality figures for 2008. Researches believe that that year, Australians over 25 spent 9.8 million collective hours in front of the TV, and that as little as one hour can take 22 minutes off your life - or about the same amount of time as smoking a cigarette.
Spending more time in front of the TV will likely result in less physical activity, and the National Lung Heart and Blood Institute recommends moderate-intensity aerobic activity or 75 minutes a week.

It's no secret that eating well and exercising are key components to enjoying the golden years of retirement. Though it can be easy to forgo working out a few days a week to instead go to a concert or enjoy a night out with friends, making an effort to pump iron could mean boomers will have more time to enjoy life and all its splendors.
Social activity is a critical component of a healthy retirement, but as baby boomers get older, many of them may find it more difficult to maintain their circle of friends. Whether it's from leaving the workforce, people moving away or simply the result of growing apart, a lack of social engagement can sneak up on older adults.
Most retired adults recognize the importance of staying physically active as they get older, but one man has taken that to heart perhaps more than anyone else.
