Several years ago the deaths of several airline travelers led to warnings about "economy-class syndrome." The idea is that economy-class passengers don't have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods on flights-conditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in the plane's cabin during a long flight may lower the risk that a clot will form.
