בֶּן־שְׁמֹנִ֣ים שָׁנָה֩ אָנֹכִ֨י הַיּ֜וֹם הַאֵדַ֣ע ׀ בֵּין־ט֣וֹב לְרָ֗ע אִם־יִטְעַ֤ם עַבְדְּךָ֙ אֶת־אֲשֶׁ֤ר אֹכַל֙ וְאֶת־אֲשֶׁ֣ר אֶשְׁתֶּ֔ה אִם־אֶשְׁמַ֣ע ע֔וֹד בְּק֖וֹל שָׁרִ֣ים וְשָׁר֑וֹת וְלָמָּה֩ יִֽהְיֶ֨ה עַבְדְּךָ֥ עוֹד֙ לְמַשָּׂ֔א אֶל־אֲדֹנִ֖י הַמֶּֽלֶךְ׃
我今日已經八十歲了，還能分辨好壞嗎？僕人還能嚐出所吃所喝的滋味嗎？還能再聽見歌唱男女的聲音嗎？僕人何必再成為我主我王的累贅呢？
Rashi
Between something good or bad? Between good food and bad food. Our Rabbis of blessed memory said, He overindulged in sexual relations causing old age to overtake him.7Shabbos 152a. Otherwise even an eighty year old man would not have deteriorated to that extent.
