Interesting facts about the human body that you may not have known. Our body is a perfect machine that makes thousands of processes every minute, while, for example, we are reading this article. Moreover, most of them we do not even suspect.

Findinterestingfacts.com has collected some incredible facts about our body that will definitely surprise you:

  1. You cannot sneeze with your eyes open. During sneezing, all the processes in your body stop for a second. The speed of the sneeze spreading is 100 mph (161 km / h).
  2. You have as many bacteria in your mouth as people inhabit the planet Earth. Sometimes there can be even more! When a man kisses his girlfriend, he has much more chances of catching any nasty things than during friendly kiss with your favorite dog. The dog’s mouth has fewer dangerous bacteria. But of course kissing with a pretty girl is more pleasant!
  3. Your hair-spring can sustain the weight of an apple. The scientists do not specify the size of the apple. If you collect all the eyelashes that you lost in your life, and put them in a chain, it will be at least 1,100 inches (30 meters). Your hair (I mean, on your head) live from 4 to 6 years. If a man stop shaving, his beard can grow up to 354 inches (9 meters). There are much more minerals, zinc and copper in the hair of smart people than in hair of stupid not very clever ones. The length of hair that you can theoretically grow over a lifetime is 450 miles (725 km). Your hair is 5,000 times thicker than the walls of the soap bubble and 20 times thicker than the cobweb.
  4. Your tongue patterns are absolutely unique, remember this when you show it to bad people! By the way, the tongue is the strongest muscle of your body. And not what you thought of proudly. Men have much less taste buds on their tongues than girls do. Therefore, they adore ketchup and mayonnaise and do not take offense at it :) White coating on the tongue that you see in the morning is not much as cells which died during the night.
  5. The mucous coat of your stomach is renewed every 3 days. Besides, there is so much acid in your digestive system that you can easily digest an iron nail. However, we do not recommend experimenting – just take my word for it!
  6. In the morning, you are always higher than in the evening – because the spine is compressed during walking under the weight of the body, and straightens at night.
  7. Your brain becomes lighter every year as you age. In addition, most of your brain consists of water. There are 100,000 chemical reactions per second in your brain. Your brain generates much more electrical impulses during the day than all the phones in the world.
  8. The average human produces about a liter of saliva daily. Some of the scientists believe that all saliva, which you have produce over the course of your life, can fill two pools (better it will be water).
  9. During the day you let out about a liter of gases, in 2 variations – in burp or in a fart, as scientists have found out.
  10. Scientists warn that most diets for weight loss can shorten your life for several years. Are you fond of starvation? It’s a good thing, but do not starve more than 1 day – otherwise, you may have permanent headaches, weakness and lethargy. In addition, fasting is harmful for diabetics and those who suffer from heart diseases.
