Warning: Flying is bad for your health
Flying is the safest way to travel - or is it? Some doctors think the airplane is a dangerous place, especially for the old or the unhealthy.
Although the airplane is pressurized, there is less oxygen than on the ground. So anyone who has had a heart attack should not try for at least two weeks after the attack. After an operation, you should stay on the ground for at least ten days.
Sitting on a plane for many hours – especially in economy class where there isn’t very much leg room – gives everyone [10] aches and pain, so you should get some exercise, especially on long flights.
Flying also causes dehydration. If you drink or eat too much, you’ll wake up feeling sick. Everyone needs to drink more in the air, but you shouldn’t drink alcohol because it makes you even more thirsty.
The most common problem is jet lag. You should change to your new time zone as soon as possible, and you shouldn’t sleep if it’s still daylight.
Crowded airports, long lines, and delays cause stress and high blood pressure. So, be careful! Flying is the safest way to travel, but is it the healthiest?

B) INCORRECT: pois o texto não afirma que as dores deveriam mudar a saúde, o que está sendo dito nessa alternativa.
C) CORRECT: uma vez que a alternativa diz corretamente que as dores podem ser causadas pelo fato dos voos longos manter as pernas em uma posição por muito tempo sem esticá-las.
D) INCORRECT: pois o texto não diz que os passageiros deveriam se exercitar antes do voo, mas sim durante o voo, em especial os voos longos.
