3. You’re Either a Morning Person or a Night Owl (and Morning People Are More Productive)
3. 你要么是個早起的鳥兒，要么是個夜貓子（且早起的人效率更高）

Most people think of themselves as either morning “larks” or night owls, but there’s more to sleep cycles than that. People have different energetic times during the day that aren’t necessarily tied to our preference for sleeping late or getting up early. And you know that saying “the early bird gets the worm”? While our society—the workplace and school systems—seem to reward morning people, night owls can be just as productive and creative as their counterparts. In fact, doctors say schools should start later in the day for the health of students, who aren’t getting enough sleep. (I’d be up for later workday start times too.)
大多數人都認為自己不是早起的鳥兒就是夜貓子，但睡眠周期不只是這些。人們一天之中精力充沛的時間各不相同，與喜歡睡得晚一點或早一點關系并不大。你知道有句俗話叫“早起的鳥兒有蟲吃”嗎？我們的社會——工作單位和學校，似乎都鼓勵早起，但是夜貓子可以像早起的人一樣高效且富有創造力。實際上，醫生說現在的學生睡眠不足，學校應該把上學的時間推遲一點，這樣有益于學生健康。（我覺得也應該把上班的時間推遲一點。）
