True holistic prevention

“In the old days the sages treated disease by preventing illness before it began, just as a good government or emperor was able to take the necessary steps to avert war. Treating an illness after it has begun is like suppressing a revolt after it has broken out. If someone digs a well when thirsty, or forges weapons after becoming engaged in battle, one cannot help but ask: Are not these actions too late?” (Yellow Emperor Canon)
