Humans have been puzzled by things like the depths of the ocean and outer space. But one equally mysterious object has been standing right in front of you when you look in the mirror. It’s a human body.

And one TikTok creator named Knowledgesaurus has been stripping away the mystery surrounding it in a series of “How Rare Is Your Body?” videos. From explaining what percentage of people have features like cracked tongue, angled palm crease, or an extra rib, to counting how many people have the ability to write with both their right and left hands, or can make a clover out of their tongue.

The informative and fun videos gained Knowledgesaurus immediate popularity with millions of views and 1.3M followers, so let’s see some of the most interesting body facts that will pump your biology knowledge muscle so you can show it off in the next trivia session.

    “I’m 25 years old and have been an entrepreneur since the age of 19. I found success with that early on and ended up dropping out of college.

I started this account 1/1/2021 with the goal of growing it and making it my full-time job and within 110 days, I was able to reach 1 million followers, which I’m so thankful for!”

    When asked how he came up with the idea for the "How Rare Are You?" series, Knowledgesaurus said it started after making a bunch of videos and seeing what people enjoyed watching. “I realized that people love to know information about themselves and love statistics. So that’s how the series began.”

    “I always loved knowing random useless information to surprise people with,” the content creator said and added: “I think it all started when I was younger. If someone was talking about something I didn’t know much about, I would go and look up stuff about it and find interesting information about that topic so I could have a better conversation next time.”

    I have it, but am tone deaf. The musical note groups a-d & e-g sound the same to me. Languages on a scale (tonal languages) are impossible for me. On top of that I don't hear a lot of high tones. Imagine going to an opera, hearing music, seeing the soprano move her mouth and not hear her voice or hear it blotchy. The lower tones I can hear perfectly fine & occasionally succeed in differentiating the difference in the tones.

    Mom and I have them. For both of us if we are listening to music we can hear it is not right when others don't notice it. If listening to an orchestra we can tell which instrument section it's in. It's like nails on a chalkboard. If it's on TV, change the channel. If it's at a concert and we can't leave it's almost painful to listen to. And I agree. It's not an abnormality. It was oh so handy in music class.

    And how can that help in sensing voice tonality? It does nothing to redirect more sound to the eardrum. This can only be true if this abnormality is always accompanied by something else, internally, that does have an effect on sensing voice tonality.

    Why does it need correcting? Isn't it just a cosmetic difference? Shouldn't it be up to the child to keep it or change it once they're old enough to make the decision, as long as it isn't impacting their hearing?

    Need or want? My teeth aren't perfect and if I was an actor or something, I would've 'needed' braces, but health-wise I don't. So do they mean 75% will have health problems if they don't get work done, or just that it looks ugly?
