SUMMARY
17 Jaw-Dropping Facts You Didn't Know About the Human Body:
- When you are awake, your brain is known to generate electricity in the amount of about 15-25 watts. This power is quite enough to keep a low-wattage LED lamp shining!
- The fun part: the enamel which covers the top of your teeth is the hardest part of your whole body.
- Hydrochloric acid is a typical "inhabitant" of a human stomach. This type of acid is industrial-grade and can, in fact, destroy metals!
- Even the content of your bloodstreams such as vitamins, drugs, or alcohol, can be found out from a strand of hair analysis.
- According to scientists, there are four main facial expressions: angry, afraid/surprised, happy, and sad. Based on these, all the rest of 7,000 expressions are performed.
- Babies are born with as many as 270 bones. Later on, some of the bones start fusing together, for instance, the bones of the spine.
- The resolution of the human eye is estimated to be around 500 megapixels. It makes them 72 times more precise than the rear camera of iPhone 6.
- The skin weight makes lifting up another human being so difficult. Another interesting fact about your skin is that every square inch of it is covered with more than six hundred sweat glands.
- You always have a blend of old and new bones in your body.
- A person blinks on average 15 times a minute, though it is proved that women do it twice as often as men.
- Only one percent of the blood they filter turn into the urine, the rest is redistributed throughout the body. A kidney of an adult isn't big at all, in fact, its size can be compared to that of a fist.
- Humans retain a tiny fold in the inner corner of the eye. It is what is left from a membrane birds, and mammals have had for protecting the eye and sweeping out debris, at the same time providing visibility.
- People who donate part of their liver to those who are in need, don't have to worry about their health. Their liver will soon regenerate the part which has been donated.
- Music, especially the one that contains a continuous increase in volume or tempo, makes your heartbeat synchronize with it.
- The enzymes make human organs start to digest the body. And they then team up with microbes, and the process of decomposition begins.
- All plants, animals, your food, even your car contain pieces of distant stars.
- This fist-sized organ beats around 115 thousand times a day and pumps 2,000 gallons of blood. In a lifetime, the number of its beats can reach 3 billion!

So shark teeth and our teeth are the same, yet sharks keep replacing theirs while we only get two sets? Something's not right here. 🤔

[@victherocker]

they are as strong, not the same. There's a difference

[@autumn5891]

They might be sharper which can tear through flesh but they have the same strength as ours

[@jakesethner5647]

kirara2516 the people who made this video are so full of s*** you can see it on their teeth when they smile.
