Long flights, clot link unclear

You've seen all of the warnings about blood clots forming on long haul flights if you sit still, but a new study suggests that such inactivity may not actually increase the risk of clots.

On the other hand, the findings suggest that keeping your whole body, or a single limb, immobile due to paralysis or injuries could put you at risk of blood clots that may spread to the lungs and cause serious harm or death.
