I pity men who occupy themselves exclusively with the transitory in things and lose themselves in the study of what is perishable, since we are here for this very end that we may make the perishable imperishable, which we can do only after we have learned how to appreciate both. [ Johann Wolfgang von Goethe ]

Since I was seven years old I have seldom take, a dose of medicine, and have still seldomer needed one. But up to seven I lived exclusively on allopathic medicines. Not that I needed them, for I don't think I did; it was for economy; my father took a drug-store for a debt, and it made cod-liver oil cheaper than the other breakfast foods. We had nine barrels of it, and it lasted me seven years. Then I was weaned. The rest of the family had to get along with rhubarb and ipecac and such things, because I was the pet. I was the first Standard Oil Trust. I had it all. By the time the drugstore was exhausted my health was established, and there has never been much the matter with me since. [ Mark Twain, Seventieth Birthday speech ]
