The Kiss of Life - New York Times

The Kiss of Life - New York Times: "According to some cultural historians, it is only within the last 800 years, with the advent of effective dentistry and the triumph over halitosis, that the lips were freed to become an erogenous zone."

Surprisingly interesting article -- who would have thought in our society today that kissing is anything but universal amongst humans. See, everything is socially constructed...

On a side note, we have a perfect example of confused correlation and causation in the final paragraph. The morning kiss is a proxy for happiness or sense of well-being or not-rushedness, not the cause in and of itself of higher incomes or fewer car accidents.
