Fact 1: So you desperately want to make out with your significant other but don’t know how? Never fear! The internet (and magazines such as Cosmopolitan) is here! If you look up “How to make out” on the web, you’ll find a ton of articles that show you how. In fact, Wikihow has a 15-step article which shows you how to master the art of kissing!

Fact 2: Kissing is technically a workout and not just one for your face. When sharing a kiss, you’re working 146 muscles, all working together to get the best out of that lip-lock. That’s 34 facial muscles and 112 postural muscles, to be exact. Orbicularis Oris is the muscle in your mouth responsible for puckering up when you kiss.

Fact 3: You’ll never get this! Rats and humans have a surprisingly similar genetic make up, and we got our love for kissing from an ancient type of rodent called Eomaia Scansoria! The rat would kiss its mate by rubbing noses to get a whiff of the other’s pheromones and to signal sexual desire.

Fact 4: Back in 1990, France passed a law that banned kissing on the railways! Apparently, all that kissing caused delays for trains to head on out of the station on time. Commuting on train during the 29^th century in France was tough business, seeing as so many train goers would get frisky on the platforms and in the trains!

Fact 5: The study of kissing is called Philematology, and scientists who specialize in this field are called Osculologists. Behold, the gods of kissing!

Fact 6: Ever wondered how long two people could last making out? Wonder no more! The two champion kissers hail from the land of Tinaranat, Thailand. Ekkachai and Laksana reportedly had a kiss that lasted 58 hours, 35 minutes, and 58 seconds!

Fact 7: Listen up, fellas! Men who kiss their wives every morning live five year longer than those who don’t! Kissing helps burn calories relieves pain, and helps strengthen your immune system while preventing cavities. What are you waiting for?

Fact 8: If you happen to suffer from high blood pressure, might we suggest you consider having a good old make out session? Studies show that kissing is great for lowering your blood pressure. All that kissing dilates your blood vessels and is great for your heart and blood.

Fact 9: There’s a reason why kissing always makes you feel good, during and after! It’s because when you’re smooching, your brain releases a Happy Hour Cocktail of Oxytocin, Dopamine, and all sorts of endorphins that sends you to Cloud 9.

Fact 10: Inevitably, sharing a kiss with someone also means sharing their saliva-and all the bacteria that comes with it- too. Even a short, sweet kiss can have you and your significant other swapping 300 types of bacteria, with a longer smooch resulting in over 80 million!
