You might want to exercise if you are taking a long trip, or know that you will be sitting for a long time it could save your life.
Whether you are on an overseas flight, cross-country train trip or simply doing a lengthy stationary activity, sitting tight for extended periods of time could lead to a potentially life-threatening condition called deep vein thrombosis. When that happens, a blood clot forms in the body's deep veins, particularly in the legs. Sometimes the clot breaks off, travels through the bloodstream and a vessel in the lungs, restricting blood flow. This condition, called a pulmonary embolism, damages tissues and causes poor lung function, which can be fatal.
