Kissing. It’s fun. Extremely fun. It’s definitely a past time for humankind. But why do we do it?
A really interesting video by Vsauce explains the science behind making out. In it, the YouTube channel’s co-creator Michael Stevens examines the time-consuming act. The average human spends 20,160 minutes of their life on Earth kissing. Wow – how are we able to hold jobs?
Michael goes on to tell us things we already know about kissing. It feels good. Yep, it does. We all know kissing is a pre-cursor for sex. Let’s be real. And sex feels good, doesn’t it? At least, it’s supposed to. According to Michael, kissing also releases epinephrine and norepinephrine into your blood; both are hormones that help regulate heart rate – what we know as adrenaline. Kissing is also correlated with a reduction of bad cholesterol – okay so not only does it give us butterflies, but it’s good for our health. That's awesome.
What we didn’t know was that a passionate kiss burns about 2-3 calories per minute. Damn – is this for real? That sounds like the best weight loss plan ever. Sign us up now.
Evolution psychologists have argued that kissing is derived from “kiss-feeding,” the exchange of pre-chewed food from one mouth to the other. Birds do it. Many primates do it for their offspring. Last year, actress Alicia Silverstone got chewed up (yes, pun intended) by what feels like the world for mouth feeding her son Bear Blu.
