《汉书·传·王贡两龚鲍传》
如今我贱龄已八十有一，气血衰竭，耳已不聪，目已不明，不可能对国家对朝廷有所贡献了，衹是所谓空食俸禄，有损朝廷形象的废人罢了。
臣禹犬马之齿八十一，血气衰竭，耳目不聪明，非复能有补益，所谓素餐尸禄洿朝之臣也。
Now, in my humble old age, I am eighty-one. My blood and spirit are in decline. My hearing is dull, and my eyesight is cloudy. I can no longer contribute to the nation or the court. I am just a mere good-for-nothing, eating my salary while sullying the reputation of the court.
