〔R83〕  I raise nothing though I sound like someone that raises cattle or anything worth raising for me or for you. Thanks to me, in fact, the old man looks younger and less repulsive though only for a day or two.

〔譯註〕 我不養什麼，雖然我聽起來像養牛的人或養任何對我或對你值得養的東西。事實上，由於我，老頭子看起來年輕點，也較不會討人厭，雖然只有一兩天。

〔提問〕 If I am very sharp, what am I?
