專家揭祕最佳工作時長：一週40個小時
There's a reason why we call your day job a "9 to 5." That's eight hours a day we're supposed to be working, which equates to 40 hours a week. If you're justifying the hours with the fact that you're getting more work done, you may be wrong。
我們爲什麼把工作叫做“朝九晚五”，那是有原因的。因爲朝九晚五的工作正好是一天工作8小時，摺合一週工作40小時。如果你認爲工作時間越長，就能完成更多的工作的話，那麼你可就錯了。
In the early 1900s, Ford Motor ran dozens of tests to discover the optimum work hours for worker productivity. They discovered that the "sweet spot" is 40 hours a week — and that, while adding another 20 hours provides a minor increase in productivity, that increase only lasts for three to four weeks, and then turns negative。
在20世紀初，福特汽車經過多次實驗發現了最優的工作時長，那就是一週40個小時。如果增加20個小時，生產力也只會有小幅上升，而且這種生產力的提高只會持續三到四周，之後生產力就會下降。
Anyone who's spent time in a corporate environment knows that what was true of factory workers a hundred years ago is true of office workers today. People who put in a solid 40 hours a week get more done than those who regularly work 60 or more hours。
任何一個在公司上班的人都知道，100年前適用於工廠工人的這個最佳工作時長在今天仍然適用。每週紮紮實實工作40個小時的人比固定每週工作60個小時或更多的人能完成更多的工作。
Adding to that, people who work long workweeks have a higher chance of burning out. What about you — do you work more than 40 hours a week?
另外，長時間工作的人更容易產生工作倦怠感。那麼你呢？你每週工作超過40個小時了嗎？
