Thing is, night people are forced to follow morning people schedule almost all life long (school, work, etc.). So they are used to wake up (too) early, and since they are night people, they can't sleep in the evening nevertheless. So the "awake from 8:00 a.m. to 2:00 a.m." is more or less the rhythm to which they are used (even if it exhausts them). The lazy bunch called morning people are not used to undergo this.
