The Story of Philosophy《哲学的故事》第1章Plato第7节VI. The Psychological Solution第3段第3句：

For the first ten years of life, education shall be predominantly physical; every school is to have a gymnasium and a playground; play and sport are to be the entire curriculum; and in this first decade such health will be stored up as will make all medicine unnecessary. "To require the help of medicine because by lives of indolence and luxury men have filled themselves like pools with waters and winds, … flatulence and catarrh — is not this a disgrace? … Our present system of medicine may be said to educate diseases," to draw them out into a long existence, rather than to cure them. But this is an absurdity of the idle rich. "When a carpenter is ill he asks the physician for a rough and ready remedy — an emetic, or a purge, or cautery, or the knife. And if anyone tells him that he must go through a course of dietetics, and swathe and swaddle his head, and all that sort of thing, he replies at once that he has no time to be ill, and that he sees no good in a life that is spent in nursing his disease to the neglect of his ordinary calling; and therefore, saying good-bye to this sort of physicians, he resumes his customary diet, and either gets well and lives and does his business, or, if his constitution fails, he dies, and has done with it" (405-6). We cannot afford to have a nation of malingerers and invalids; Utopia must begin in the body of man.
浙江大学译本：但这是属于无聊富人的滑稽问题。

解析

1、But this is an absurdity of the idle rich.
但这是无所事事的有钱人的荒谬生活。

这句用简短的话概括了前面一句。病是生活习惯带出来的，而药物只是惯着“病”而非治愈它们。这样荒谬的事就发生在那有无所事事的有钱人身上。穷人是没有时间用来生病的。
