如今，在這個強調速度與高效的社會里，人們的生活節奏也變得越來越快，做事時常常要一心多用，導致腦負荷太重，導致張口忘詞，做事不過腦子或突然冒出無厘頭蠢話等“腦子短路”(brain fart)的事時有發生。

It happens to you all the time. You're mid-sentence during a meeting with your boss, working on The New York Times' crossword puzzle, typing up an essay for grad school, or even talking to your mom on the phone — and the next word you're looking for just doesn't ... come.
這種事在你身上時有發生：在會上和領導正說著一半話，正玩著《紐約時報》上的字謎游戲，寫著畢業論文，甚至和你媽在講電話時，卻忽然忘記要說什么了……

There's a scientific term for this totally common phenomenon, which we like to call a "brain fart." "Brain fart" is used to refer to a temporary mental lapse or failure to reason correctly.
這種非常普遍的現象有個學名，我們稱之為“大腦短路”。"大腦短路"是指暫時的大腦失靈，無法正確地進行推斷。

Below is a list of brain farts that pretty much everyone has had one time or another.
下面就是我們每個人都很可能曾經做過的腦子短路事件清單：

1. Having trouble spelling a word you've spelled a thousand times before.
寫不出那個你已寫過一萬遍的字。

2. Trying the door even though the sign says, "Close".

3. Forgetting your own age.

Reply: "You too".
答道：“你也是。”

6. Checking your watch, then checking it again because you weren't paying attention.
看了下表，然后又看了一次因為之前注意力沒在這。
