What's the matter , sir ? You look pale .   I feel dizzy and weak . And I'm having this pain in my ear . I think I am sick .   Are you often traveling by plane ?   No , this is the second time .   That's right . It's normal if you don't often take the plane . Just relax a little bit .   Why this happens to me when I am on the plane ? I feel bad .   Don't worry , sir . It's just because of the lower pressure .   What should I do about it ?   You may feel much better if you chew some gum or peanuts .   OK , thanks . Does it work really ? I'll give a try .   Are you feeling better now ? Do you need some pills ?   Much better . Thank you . I just feel tired but I can't fall asleep .   So , you'd better wear this eyeshade and you will sleep well .   I am not used to wearing that . Thanks .   If you try to adapt yourself to your destination's local time , you'll feel more comfortable . So please try to sleep , and have meals according to Los Angeles's time .   Thank you so much .
