Blood clot deaths tied to hours of daily TV time

(Reuters Health) - People who watch television for five or more hours a day have more than twice the risk of those who watch half as much TV to die of a blood clot in the lung, a large Japanese study suggests.

There are more than 200,000 cases of pulmonary embolism, which usually begins as a blood clot in the leg that travels to the lung, in the U.S. each year, according to the National Library of Medicine. It can permanently damage lung tissue, other organs, or cause death, but many people who have it have no symptoms.
