Researchers say it could be a killer combination.
New research shows owning the conveniences of a car, a computer and a TV simultaneously could lead to serious health concerns down the road.
The research comes from the Canadian Medical Association.
Scientists there found people who owned all three, usually sat more and moved less than people without them.
Researchers studied more than 150,000 people from around the world.
They found those who owned a car, computer and TV were 31 percent less active, and had a 21 percent larger waist which measures about four inches larger.
Researchers believe this could foreshadow serious health problems in developing countries, like the spread of weight-related conditions like diabetes or high blood pressure.
