Jet lag occurs when your body's circadian rhythms fall out of sync with your surroundings, such as when you quickly move to an area that is 12 hours behind where you were previously. One thing that certain helps to adjust is exposure to sunlight--cells in your retina use this information to tell the brain that it is daylight, and that the body should be awake.

For nearly half a century, social scientists have operated under the assumption that all basic human emotions are universally recognizable. Countless cross-cultural experiments—not to mention a few television shows (eg Lie to Me)—have both directly and implicitly referenced the notion that every person on earth expresses facial emotion in the same way. Regardless of cultural context, we can all interpret happiness, sadness, anger, fear, and disgust in the expressions of the people around us... right?
