Sleeplessness does harm to people’s health.

Few people really know the importance of sleep.

Average people probably sleep less than the rich.

答案及解析：本题考查判断推理。题干问的是作者在最后一段所表达的观点，定位到最后一句If the most health conscious among us have such deep swings in our shuteye levels throughout the year, how much sleep are the rest of us losing? 作者提到了health-conscious，人们对健康的意识是缺乏的，对健康是视而不见的，综上，B选项正确。 故正确答案为B项。
