We have all tried to lick our elbows or touch our noses with our tongues at least once. However, there are many strange and funny facts about the human body that might surprise us. Let’s discover what else our bodies are or are not capable of.
Yes, you heard it correctly! When you listen to music, the beat is automatically mimicked by your heartbeat at that time. Cardiovascular changes as well as a physiological reaction can occur due to music. According to a study by Luciano Bernardi, music boosts the mood by inducing pleasurable “chills” in the body.
The Number of Bacteria in the Mouth Exceeds People in the World
There’s a lot more bacteria in your mouth than there are people in the world. Even those people who take care of their oral hygiene have between 1000 to 10,000 bacteria living on each tooth. Those with lesser clean mouths have between 100 million to 1 billion bacteria on each tooth surface. That means approximately 32 billion bacteria. The population of the world is 7 billion. That is something to think about the next time you skip brushing your teeth.
In comparison to a digital camera, the human eye would have 576 megapixels. However, the lens of the eye is more like a video camera than a snapshot camera. It’s rapid angular movements allow one’s brain to paint the detail of the image. Along with that, we are equipped with not one, but two of our own personal cameras. Therefore, our eyes typically move together to clarify the details of a scene. The eye and the brain combine to give a sharper image and a higher resolution.
The Human Brain can Produce Enough Electricity to Light a Small Bulb
There is further proof of how the power of our brains must never be underestimated. There are billions of neurons in our brain. While one single neuron does not generate much, all the neurons collectively can produce enough electricity to power a light bulb while we are awake. Tiny electrical and chemical signals are being sent to the brain no matter what we do. In that way, all our actions generate electricity.
Fat and muscle cells stop dividing and bones stop growing after puberty. However, cartilage, the stuff found in the ears and nose, continues to grow till you die. Moreover, due to gravity, the earlobes continue to elongate as well. That is why the ears and nose never stop growing.
Just like fingerprints, tongue prints are also unique. That is why it is very difficult to confuse two identities realistically. The tongue also happens to be the strongest muscle in the body, with taste receptors that help identify flavors.
Millions of Different Colors are Distinguished by the Human Eye
A number of scientists have come up with the hypothesis that humans can distinguish between millions of colors. This is due to the spectral composition of light as well as the presence of trichromatic vision in humans and apes. When light is reflected from surfaces, it creates a huge variety of hues and shades. The trichromatic vision is when the eyes contain three primary color receptors that are sensitive to the three primary colors. Therefore, we are able to view different colors that originate from light itself.
According to Dr Aikarakudy Alias, people who have a higher intellect than the general public are likely to be more hairy. His research suggests that the hairier men comprise of more doctors and engineers whereas manual laborers are less hairy. Additionally, in one of his studies, hairier men got higher grades.
Tiny eyelash mites, or “Demodex” exist in our eyelashes. These mites are usually not harmful to the eyelashes but each individual has specific mites that inhabit their eyelashes. That is the reason why mascara should never be shared. The mites can easily be transferred to the mascara wand and into the tube. Therefore, you may be at risk of catching mites from others if you share a mascara.
We Can Fill Two Swimming Pools with Saliva During Our Lifetime
The amount of saliva produced during the lifetime of an average person is about 25,000 quarts. That is enough to fill two large swimming pools. Saliva is being constantly produced, whether we are awake or not. Sometimes, just the mention of something delicious can activate one’s salivary glands.
All in all, the more we study our bodies, the more strange and funny discoveries we will make.
