But it also beguiles us with its endless mysteries, allowing us to ponder why different languages emerged, why there isn't simply a single language, how languages change over time and whether that's good or bad, and how languages die out and become extinct.

Conventional wisdom suggests English is going to the dogs, that bad grammar, slang, and illogical constructions signal a decline in standards of usage - to say nothing of the corruption wrought by email and text messages.

And these forces continue to push English in exciting new directions.

Eating is an indispensable human activity. As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man."
