Dr. Z:	Actually, I have the perfect example for you. Once, an American high school student managed [staying / to stay] [awake / waking] for 264 hours, [breaking / break] the [latter / previous] record of 260 hours. But he had some [disturbing / disturbed] [physiological / psychological] problems along the way.

Dr. Z:	There's no magic number of hours [that / when] a person should sleep. For one thing, it depends on your age. On average, babies spend about [as twice / twice as] much time [to sleep / sleeping] [as / than] adults. This means that there was a time [which / when] you slept [as many as / as little as] 18 hours a day! [However / As a result], as a teenager or adult, you only [acquire / require] about eight or nine hours of sleep, and some people need [as little as / as many as] seven hours. [How long / How far] you should sleep [is / are] also [affecting / affected by] your sleep debt; [that is / on the other hand], the amount of sleep you lose [due to / in spite of] such things as work, stress and sickness. This means that [if / whether] you lose sleep [work / working] [late / lately] during the week, you should [make up for / make up of] the time [which / when] you lost by sleeping [less / longer] on the weekend.
