Why do so many people prefer to watch TV rather than do exercise?
Lack of exercise could be causing as many deaths around the world as smoking, according to an article in the science magazine The Lancet.
As thousands of Olympic athletes prepare to push their bodies to the limit, most of us sit inactive for hours in front of a TV set.
But the scientists say they are not suggesting difficult gym sessions. As Pamela Das from The Lancet puts it: "It is not about running on a treadmill, whilst listening to your iPod."
The aim is to encourage everyone to think about fitness and build physical activity into their daily lives, such as brisk walking, gardening or any energetic pursuit.
Despite the familiarity of the message, one in three adults worldwide fails to do the recommended 150 minutes of moderate aerobic physical activity per week.
