Austrogen

The hormone secreted while reading Jane Austen novels and viewing films or stage adaptations of her work (such as Pride and Prejudice). Often stimulates the pleasure and confidence center of the reader (or Austenites).

Heightened levels usually result in feelings of being "born in the wrong era," general dissatisfaction with current romantic practices, the state of chivalry, and possibly becoming an Anglophile.

Ice Cream is known to exacerbate the effects of Austrogen on the mind / body.
