Avis put off writing her term paper until three days before it was due. "It's not that big of a deal. I can whip it out in a couple of hours," she thought. As it turned out, this was not the case. She averaged two hours a night sleep as she struggled to write the paper and turn it in on the due date. Once the project was submitted, she returned to her dorm room and collapsed into a deep sleep. Research has shown that she will:

1. sleep fitfully for several nights.
2. spend more time in REM sleep than she normally does.
3. suffer a brief period of short term memory loss as a result of the sleep deprivation.
4. suffer an extreme but temporary dip in her immune system.
