– You probably smell a lot of things every day! But you’ll never guess how many smells the human brain can memorize in a lifetime…50,000! And that’s why different smells can immediately spark a specific memory.
– It’s easy to open your mouth and talk, right? Then you’ll be shocked to know that 72 different muscles are behind your ability to speak.
– Speaking of the heart, it can actually beat outside the body! Thanks to a machine called the Organ Care System, or OCS, donor hearts can be kept alive longer during transport, increasing travel time by up to 12 hours!
– While it might not look like it from the outside, your small intestine is 23 feet long. So if you could stretch it out and hold it up, it’d be taller than an adult giraffe!
– Ever notice how a lot of your organs come in pairs, like the lungs and kidneys? It’s so that if you were to lose one, your body could still function with the other. That’s how people can donate a kidney and still live on the one they have left.
– Speaking of the voice box, humans, unlike other primates, have one that sits lower in their throat. That’s why people make such a wide array of sounds. If that’s the case, then Mariah Carey’s voice box must be way down in her stomach!
– Adults are recommended to drink around 2 liters of water a day. That means by the time you’re 70 years old, you’ll have chugged down 51,000 liters, which is over 13,000 gallons of water!
– Your tongue has patterns on it that are completely unique to you. Your teeth are also one-of-a-kind, and no one else can have the exact same dental print as you either!
– The word “muscle” comes from a Latin term that translates to “little mouse”. Ancient Romans thought muscles looked like little mice, so the decided to call them as such.
– Blushing requires you to be aware of what others think about you, which humans are definitely capable of. That being said, some people are more susceptible to blushing than others.
– So it’s no surprise that humans share 98.4% of their DNA with chimps. But did you know that you also share 70% of your DNA with slugs and 90% of it with domesticated cats?
