Q. Are long flights dangerous? I'm flying next week to my vacation, and the flight is going to be rather long (almost 16 hours non-stop). Several years ago, my 75 years-old aunt had blood clot in her lung after a flight of similar length. I also heard that during flight the blood in the legs clots and that it can cause after that problems with the lungs and breathing. Does this mean it's dangerous for me to fly? Should I change my ticket to shorter connection flights?

A. Long flights, especially when seating in crowded cabins without moving the legs for long periods can cause the blood in you legs to clot and after that to move to your lungs and damage them. You may try to move your legs during the flights (like getting up and walking a little etc.) This video has some suggestions:
