Jet lagWhen you travel (1) on the other side of the world, jet lag is a real problem. You find yourself away in (2) the middle of the night and you feel like going to bed in (3) the morning, just when everyone around you is getting up. Jet lag happens when you go in (4) a country where the time is very different. For example, you might leave London at (5) midday and fly in (6) Los Angeles. The flight takes about eleven hours, so when you arrive (7) at Los Angeles airport, your body thinks you\'re there (8) at 3 p.m. local time. So, at (10) midnight Los Angeles time, your body (which still thinks it\'s (11) in London) says it\'s 8 am. It takes a few days for your body clock to change.
