This is the scenario. You are staring into her eyes while she stares into yours. Instinctively, you embrace her and pull her close. She touches your face while you lean in and your lips connect. The sensation leaves you breathless and you can’t even begin to wonder, “Why are we kissing anyway?” The question has been on the minds of countless individuals in the past and present. But only a select few dared to question why it occurs.
The simplest information for this phenomenon is the humans kiss because it feels good. However, is this explanation sufficient? Some scientists have studied the history of kissing by looking at the human anatomy and history. So far, these scientists haven’t been able to explain where and why kissing occurs though there are certainly a lot of theories.
Is kissing an instinct or is it learned? Many believe that it is a learned behavior dating back to ancient times. Back then, mothers had to chew food and then pass it on the mouths of their children. Supporting this theory is the fact that there are tribes that don’t kiss at all. On the other side of the spectrum are those who support the theory that kissing is an instinctive behavior.
Why instinctive, you would ask. Well, some scientists believe that animal behavior is proof. Most animals rub themselves as a sign of affection but there are animals that do pucker their lips like people. Look at the bonobos, for example, they make up after a big fight, they kiss to comfort each other, and they develop bonds just like humans. Similarly, they sometimes kiss each other for no apparent reason.
Right now though, there is a more interesting theory. It seems as if some people believe humans kiss to sniff a potential mate. Kissing is said to be a way to find a quality partner because kissing allows pheromones to “communicate” biological information about whether or not the offspring will be strong and healthy. It has been studied that women unconsciously prefer a male scent with an immune system different from their own. This will make their offspring stronger.
No matter the kind of theory and explanation that people might think of though, those who enjoy kissing are content. They live for the tingly sensation of lip locking, the pulse of the nerve endings, and the dizzying sensation that comes with intimacy and falling in love.
Fun Facts
Gas prices are always a problem for an average consumer. But people are confused about the difference between gasoline and diesel? So what makes it distinctive from each other exactly?
Start with its origin. The black gold (aka the crude oil) undergoes a process known as fractional distillation at the oil refinery. This process will separate the components on the crude oil based on the substances’ boiling points. The first to go is the propane, a highly flammable compound. And the last is the bitumen which is sometimes used to tar roads because it will only go at the highest temperature in the refining process. In between these two extremes are the energy source we commonly use including diesel, gasoline, and kerosene.
In actuality, the gasoline is actually the substance from the crude oil mixed with products from the refinery. Depending on the ratio provided, various grades of gasoline can be formed. That’s the reason why you have the option to get regular, super unleaded, and premium gas at the station. One of the things you might have noticed is the octane rating. Before you think this is a complicated thing to understand, realize that it is merely an indication of the hydrocarbon found in the gasoline. This particular substance will lower the chance of premature “detonation” also called knocking. Having a higher octane rating means that you will have better knock resistance.
Meanwhile, we go to the diesel fuel. This energy source has a lot of positives but it has its negatives as well. Diesel is preferred by various motorists because it is 20 perfect more efficient. More energy is produced per unit but it also has high sulfur content. It makes diesel dirtier and produce soot. The sulfur content has also been associated with the diesel smell that everyone simply hates. It is a good thing that new technologies are being created to produce the low-sulfur diesel that has low emissions as well.
The technical uses of the diesel and gasoline are quite different as well. Diesel is mainly used for internal combustion while gasoline is used to ignite sparks within the engine. Diesel is good for compression-based machines because this fuel will ignite when mixed with high-pressure and high-temperature air. The quick intake and exhaust associated with its use gives the diesel its popular heaving sound. It is basically up to you to decide whether you prefer gasoline or diesel. Either will work just as well.
