n.手指頭的倒拉刺

I have a hangnail, and my heart is-what? 我指甲旁有個肉刺，我的心- 什麼？

It's an environment that is at once trashy and highly exacting: every hangnail a sin, every eye-bag a crime. 但現(xiàn)在我更喜歡自然一些”凱利又補(bǔ)充說“很多人認(rèn)為人們不應(yīng)該去做整容，而我卻不是這么想的，我覺得每個人都可以做自己想做的事情”。

If one of your pros is “will make a million dollars” and one of your cons is “might get a hangnail”, they don't exactly cancel each other out. 例如，有個好處是"可以掙到百萬美金"，有個壞處是“可能手指頭會有倒刺”，這樣的利弊是無法對等，相互抵消的。

If one of your pros is “will make a million dollars” and one of your cons is “might get a hangnail”, they don’t exactly cancel each other out. 這就是說任何復(fù)雜的問題，當(dāng)影響其得因素平均超過7個時，清醒的頭腦就容不下了，就影響了有效的思考運(yùn)作，結(jié)果就是不能很好的作出選擇了。
