We rarely think about how interesting and unique our bodies are. Did you know, for example, that no human being has truly black eyes? Or that if the human eye were a camera, its resolution would be about 576 megapixels? Or that a human produces from half a liter to 1 liter of saliva every day, depending on the person. That's enough saliva in a year to fill a bathtub! Do you still think you know your own body perfectly? Okay, how about this? The only thing that differentiates blood types is... sugar, A human hair is stronger than copper wire of the same diameter, our belly button has an entire zoo in it, with a range of about 70 different bacteria. Believe it or not, there are even more wonders in our bodies that can surprise us! Today we invite you all to see this compilation of truths about the human body - many of which we never talk about. #discovertheworld Subscribe to DISCOVER THE WORLD https://bit.ly/37SkPKx Music by Epidemic Sound https://www.epidemicsound.com/ Materials used (photos, videos, etc.): https://www.depositphotos.com https://www.shutterstock.com https://www.eastnews.ru
