Kiss Day

Kiss Day takes place during Valentine's Week, on the day before Valentine's Day. Fittingly, kisses are shared between lovers today. "Kiss" comes from the Old English word "cyssan," which itself came from the proto-Germanic word "kussijanan" or "kuss." This word probably comes from the sound that kissing can make. The first written mention of kissing is in the four Vedic Sanskrit texts, which may date to as early as 1500 BCE.

The orbicularis oris, known as the "kissing muscle," allows lips to pucker. A pucker kiss only takes this and one other muscle, while a French kiss takes 34. "French kiss" is a slang phrase that came about in the English language in 1923, being so named because French culture was seen as being overly concerned with sex. The kiss is known as a soul kiss or a tongue kiss in France. About two-thirds of people tip their heads to the right when they kiss, and between 10 million and 1 billion bacteria are exchanged.
