This is true not only of food--the principle that extremes bring about their own reversal applies to many other things too. An example of current relevance is the boom-and-bust cycle of Taiwan's housing market over the past decade.
飲食如此，其他事物也終究脫不了「物極必反，天道好還」的循環。十年來台灣房市的興衰就是一個眼前的例子，三百萬國民參與的股市不也是一幕幕禍福長相倚的警世劇？
