人踢到腳趾頭時會飆髒話，為什麼呢？研究指出：爆粗口能夠啟動大腦中釋放減輕疼痛之化學物質的那一個部位。
You most likely have hundreds of microscopic mites living on your face, and because they lack anuses, their waste accumulates until the creatures explode and their feces is deposited on your face.
你的臉上極可能住著好幾百隻極小的塵螨，而因為牠們沒有肛門所以糞便會一直累積在體內直到牠們的身體脹爆，然後把排泄物留在你的皮膚上。
