In his bestselling book, "The Art of Kissing", image consultant William Cane explains that the science of kissing, called philematology, is much more than just locking lips. In fact, his blog explores over 30 types of kisses and offers kissing lessons with a surrogate.

According to the Guinness World Records News, a man and woman in London, England locked lips for 31 hours, 30 minutes and 30 seconds - making it the longest kiss ever recorded.

A French kiss involves all 34 muscles in the face, whereas a quick pucker involves only two. The term, French kiss, came into the English language around 1923 as a slur on French culture, perceived as being overly concerned with sex. In France, a French kiss is called a soul kiss because, if done right, it feels as if two souls are merging. In fact, several ancient cultures believed that mouth-to-mouth kissing mingled two lovers' souls.

Passionate French kissing can burn up to five calories in a few seconds or about 150 calories (calculation compiled by Dr Harold Katz) in a minute. Kiss for 10 minutes... and skip the gym!

According to sexologist Dr. Ava Cadell, passionate French kisses do a wonderful job of getting you in the mood. They elevate your blood pressure, make your heart beat faster and send blood all throughout your body. All this activity makes it easier for you to get excited.

Kissing is good for your teeth. The anticipation of a kiss increases the flow of saliva to your mouth and gives your teeth a plaque-dispersing bath.

Pliny the Elder, a Roman military commander and author, claimed that kissing a donkey's nostril would cure the common cold. We'll stick to chicken soup!

The mouth is full of bacteria... and when two people kiss, they exchange between 10 million and 1 billion bacteria. Yikes! Remember to brush, rinse and floss!

In "Kissing Christians", professor Michael Philip Penn explains that kissing at the conclusion of a wedding ceremony can be traced to an ancient Roman tradition where a kiss was used to sign a contract.

In "The Science of Kissing", science journalist Sheril Kirshenbaum claims that kissing can determine the fate of your relationship. Couples who are good at lovemaking - and enjoy it - tend to have longer lasting, healthier relationships.

So far, the movie with the most kisses, namely 127, is Don Juan (1926). Andy Warhol's Kiss (1963) contains the longest kiss ever filmed. Splendor in the Grass (1963) with Natalie Wood and Warren Beatty made history with Hollywood's first on-screen French kiss.

Kissing makes you feel happy, positive and less stressed because it releases endorphins and oxytocin. According to relationship therapist Dr.Krista A. Bloom, our lips are super- sensitive and have approximately 10,000 nerve endings - and that's why we love kissing so much .

Kissing is healthy and can even make you live longer. A variety of studies have shown that couples who kiss regularly tend to live longer. Even a quick good-bye kiss before leaving home can have huge benefits.

According to a University of Albany study, open-mouth kissing transfers testosterone. Men move toward open-mouth kissing faster than women do because men want to share their testosterone and thereby increase their partner's libido as quickly as possible.

Humans aren't the only creatures who kiss. Cows, puffins, squirrels and even snails indulge in the act, but chimpanzees are the only animals whose kisses resemble ours.

The "X's" that many people write at the bottom of a letter represent the contact of the lips during a kiss. Keep writing!
