Humans are the animals of exploration. Wonder, ponder, ask, inquire_curiosity drives our lives. The only quality of ours that took us to the Moon and will soon land us on Mars.
But how much do you know about yourself, your body? While you may know quite a lot, your body is a whole universe in itself and there are things you might not have heard of yet. For instance, did you know that you are taller in the morning than in the evening? and that your fingers, no matter how strong they are, don’t have muscles, and that the five senses theory is plain wrong? If you didn’t, let’s explore these and many other fascinating human body facts in this chlorine listicle.
1. Big Eyes Means Prone to Nearsightedness
Many of us consider big eyes as a sign of beauty. But that beauty comes with a price tag. Big eyes can actually cause nearsightedness. Medically termed as Myopia, nearsightedness is a condition that makes distant objects look blurry.
Due to the bigger sized eyeballs, light falls short of properly focusing on the retina, resulting in a blurry image for distant objects.
2. You are Taller in The Morning
This may seem fictional but the science behind is school-grade. During the course of the day, your body mass puts pressure on the joints and compresses the tendons and ligaments. And because joints have gaps_that’s why they are joints, these gaps narrow down, as a result, you are slightly shorter in the evening.
When you wake up in the morning, your joints are relaxed and you are taller. If you are a short person and going on your first date, no need to change the timing because the difference is actually a fraction of an inch.
3. Are You Actually More Bacteria than Human?
You have trillions of bacteria in your body, in fact, outnumbering your cells by 10 to 1 and making up 3 percent of your body weight. The total number of bacterial genes is well above 300 million which is 150 times more than human genes. And the weight!! Well, bacteria account for over 3 percent of your body weight.
And it’s not only about the numbers! These bacteria are responsible for everything including digestion, metabolism, aging, even everyday mood, and mental health.
You are actually a bacterial rainforest inhabited by tens of trillions of microorganisms, including a thousand known species of bacteria. So, are you more human or more bacteria?
4. Fingers Don’t Have Any Muscles
Tasks as simple as typing an email or playing the piano to lifting loads equal to your body weight, you do a variety of things with your fingers. Some adventuresome people even go the extra mile to display how strong their fingers are.
One such guy is Ross McCurdy who set a World record by lifting 88.96 kg (196 lb 1.9 oz) with his pinky. And you might have heard about Ho Eng Hui, a Malaysian superhuman who punctures coconuts with his index finger. And fingers can be dangerous as well, if not used with care, a single finger has the potential to turn everybody in the bus against you.
But no matter how strong your fingers are, there are no muscles in fingers. And all the strength they have comes from bones and tendons with aided support from the muscles in your palm.
5. Self Tickling Doesn’t Work
Tickling is not as simple as you might think it is. The moment someone tickles you, a whole evolutionary war turns into play.
According to studies, tickling served two basic purposes in evolution, i.e defense and socialization. And because defending against yourself and socializing with yourself doesn’t make sense, self tickling doesn’t work.
On these same bases, tickling is classified into two types. The feeling of being stroked with a feather that doesn’t provoke laughter is called knismesis, while the more familiar sensation of intense tickling, followed by heavy laughter is termed gargalesis. In spite of the fact that the later gives pleasure, the response of your body, in either case, is to repel the disturbance.
While tickling probably doesn’t serve as a defense mechanism anymore, it can still be taken as a kickstart to socialize in various ways including intimacy. This or that, tickling is a leftover from our early ancestors’ survival mechanisms.
6. You Had More Bones When You Were a Baby
How many times did someone tell you that the human skeleton is made up of 206 bones? He was not totally wrong! An adult human skeleton does have 206 bones.
Bones give you strength and the rigidity your body needs. While a baby is soft and fluffy, he outnumbers you by a staggering 94 extra bones, not to mention you did the same when you were a baby.
But there is nothing to worry. about, your body didn’t eat those bones up. As you grow, some of the bones actually infuse together to form one bone for more strength and compatibility.
Why the bones are unfused in the first place?
Most of a baby’s unfused bones are in the skull. unfused bones enable the baby to safely squeeze through the mother’s birth canal_would probably stay inside or rip the mother’s things up otherwise. This also enables the baby’s brain to grow faster and better, would otherwise be restrained.
