Anyway, what do you think? What, if anything, is "better than sex"?
You needn't be restricted in your answers, but bear in mind that the sort of things I hear it about are usually not states of mind. (Google has hits for various foods, "good music", walking, and some fields of study on the first page, for examples).
EDIT: This question was asked a little over a year ago.. if you answered before, has your answer changed (or were you just using it in the hyperbolic sense)?
