很多人都有拖延的换毛病，不喜欢的或者棘手的工作总是要拖到deadline才开始动工，能先舒服几天是几天。拖延真的能让人产生快乐吗?美国心理学家就这一问题做过实验，实验结果显示，拖延带来的不安感已经远远大于工作本身带来的压力，会让你的心情变得更糟。

　　An upcoming dental appointment can be terrifying. Soterrifying, in fact, the fear of future pain can be a worse experience than theactual pain during the procedure. So finds a study in the journal PLOSComputational Biology.

　　Volunteers had to choose a date on which they would havehypothetical, painful dental work, and choose another date to get a realelectric shock. Most subjects strongly preferred to schedule the pain as soonas possible—they felt that the dread of waiting was just too much to endure.They did not want to wait even though they were told that the shocks would beless intense if they put them off. The minority of participants who did chooseto delay their pain thought that doing so would reduce their immediate anxiety,which is the same motivation for those who wanted to get the pain over withsooner.

　　However, the delaying group suffered increasing levels ofanxiety as time wore on. So, when you have the freedom to choose, the beststrategy appears to be to rip off the band-aid, fast. Never dread til tomorrowwhat you can suffer through today.
