Case 2: As a child, Susan was an excellentsleeper. She could fall asleep quickly, and typically sleptstraight through the night, often for as long as 10 hours. As ateenager, then as an adult, she did not sleep as long as she usedto (usually about 8 hours), but still had no trouble falling orstaying asleep at night. Today, Susan is 67 years old, and althoughshe is relatively healthy, she just does not sleep the way she usedto.
