I'm tired of writing melancholic blogs. Here's something that I hope will make you smile 🙂 .. Ever noticed that when you stare at your fingers for long enough they start transforming into alien appendages before your very eyes? You see the mundane for what it really is: freaky-looking.The same goes for the rest of our traits. We take for granted that funny things make us yell out spastically — also known as laughing — and that we spend one-third of every day in a deathlike state of suspended animation known as sleep. But with a little contemplation, these behaviors seem truly bizarre.Here area fewmundane yet weird things we do all the time, and why we do them.
How odd that sadness causes water to spill from our eyes! Among all animals, we alone cry tears of emotion.
Not only do they serve the purpose of communicating feelings of distress, scientists believe tears also carry certain undesirable hormones and other proteins that are produced during periods of stress out of the body, which may explain the cathartic effect of "a good cry."
Turns out, the cheek-reddening reaction is a universal human response to social attention. Everyone does it — some more than others. Common blushing triggers include meeting someone important, receiving a compliment and experiencing a strong emotion in a social situation.
Blush biology works like this: Veins in the face dilate, causing more blood to flow into your cheeks and producing a rosy complexion. However, scientists are stumped as to why all that happens, or what function it serves.
It's weird, when you think about it, that swapping spit seems romantic. Turns out it's a biological instinct.
Kissing allows people to use smell and taste to assess each other as potential mates. People's breath and saliva carry chemical signals as to whether they are healthy or sick, and in the case of females, whether they're ovulating — all important messages for potential partners in reproduction.
Furthermore, the skin around peoples' noses and mouths is coated with oils that contain pheromones, chemicals that broadcast information about a person's biological makeup. When people pick up each other's pheromones during a sloppy kiss, they'll subconsciously become either more or less sexually attracted to each other depending on what they detect.
The answer may stink, but everything we eat or drink gives us gas. In fact, it's normal to fart up to half a gallon (1.9 liters), or about 15 to 20 toots worth of gas each day.
Particularly fragrant flatulence, however, comes from colonies of bacteria shacked up inside our lower intestinal tract. In the process of converting our meals into useful nutrients, these food-munching microbes produce a smelly by-product of hydrogen sulfide gas—the same stench that emanates from rotten eggs.
Just like the rest of us, the bacteria like munching on sugary foods best. The types of sugar naturally present in milk, fruit — and, of course, beans — produce the most farts.
The punchline of a joke hits you, and with it comes a funny feeling: You're suddenly overcome by the urge to yell out spastically, over and over. Laughing is weird. Why do we do it?
Psychologists think this behavioral response serves as a signal to others by spreading positive emotions, decreasing stress and contributing to group cohesion. For those same reasons, chimps and orangutans smile and laugh during social play too.
In fact, many hypothesize that laughing evolved from panting. When our prehuman ancestors wrestled playfully with each other, they got all panty… and that eventually turned into getting laughy.
