1. When a person travels by air, he should be aware of several important things. The first is his health. If he has a bad cold causing a stuffy nose, it may hinder the changing of air pressures in his ears as the plane rises and descends. This can cause severe pain in his ears. If one must fly when he is experiencing a bad cold, he should take medicine which will reduce tissue swelling and open his nose and ear passages.

    The second important thing to know is the luggage limitation. Failure to observe the regulations can result in extra financial charges.

    The third thing is to bring something with you to occupy your time while flying. Sometimes the airliner will have magazines available for reading, or will show you a movie during the flight, or have special earphones available to listen to music or entertainment programs. If these conveniences are not available, a person should be prepared to provide his own reading material.

    2. First aid: First aid is simple medical treatment given as soon as possible to a person who is injured or who suddenly falls ill. The most important thing about first aid is to do only what is necessary, but to do that as carefully and quickly as you can. When an accident happens, it is important to keep calm. If the person is in no immediate danger, leave him lying where he is. A coat placed under his head, a blanket over him, is the best treatment you can give while waiting for help. If the person is unconscious, loosen his clothing, especially round his neck. You can do a lot of harm if you try to do too much. If the injured person has stopped breathing, you must give him mouth-to-mouth breathing as soon as possible.
