Scientists in the Netherlands have reported that we share about 80 million bacteria during a passionate ten-second kiss; a finding that makes puckering up seem cringe-worthy. But take heart: we’re more likely to get sick by shaking hands than through kissing. And the science behind this behavior reveals that along with all of those germs, we share plenty of benefits with a partner as well.
59% of men and 66% of women will end a relationship if the kiss doesn’t go well
Our lips are the body’s most exposed erogenous zone. They are packed with sensitive nerve endings so even the slightest brush sends a cascade of information to our brains. Kisses work their magic by setting off a whirlwind of neurotransmitters and hormones through our bodies that influence how we think and feel.
If there’s real “chemistry“ between two people, a kiss can set the stage for a new romance. Evolutionary psychologists at the State University of New York at Albany found that 59% of men and 66% of women say they have ended a budding relationship because a kiss didn’t go well. It’s nature’s ultimate litmus test, nudging us to be most attracted to the people that may be the best genetic partners. We may not exactly be thinking about parenthood when we connect with someone at the lips, but kissing provides clues to help us decide whether to take a relationship further.
Aside from helping us find a great match, kissing has other perks as well. It sets off a cascade of neural impulses that bounce between the brain and the tongue, lips, facial muscles, and skin. Billions of little nerve connections distribute information around the body, producing chemical signals that change the way we feel.
A passionate kiss can spike the neurotransmitter dopamine, which is linked to feelings of craving and desire. Oxytocin, known as the `love hormone’, fosters a sense of closeness and attachment. Adrenaline boosts our heart rate and can make us start sweating as our bodies begin to anticipate what might occur later. Cortisol, known as the stress hormone, also dips to reduce uneasiness. Blood vessels dilate, breathing can deepen, cheeks flush and our pulse quickens.
Kissing fosters the sensations we often describe when we are falling in love. In this way, a kiss can herald in a new romantic relationship. It can also solidify the bonds we share with family members and friends. Kisses come in many varieties and are inherently tied to the most meaningful moments of our lives by providing a means to communicate beyond what words can convey.

Science has barely begun to study kissing, despite its obvious evolutionary and personal significance, but what we already know demonstrates that there’s a lot more to going on than meets the eyes -and lips.
Beer can make men better in bed
Men who favor a pint as their regular tipple will be pleased to hear science has made a compelling argument that drinking beer could make you perform better in bed. According to sex expert Dr. Kat Van Kirk, beer provides men with four benefits beneath the sheets, Medical Daily reports. Firstly, sloshing down a couple of brews can delay premature ejaculation. Phytoestrogens in alcohol overload the body and are proven to delay orgasm.
Drinking darker beers can also act as an aphrodisiac, boosting the libido and giving more intense erections. The iron in darker beer helps red blood cells create hemoglobin, which carries oxygen in the body. This improves circulation and gives a stronger erection.
