30 Facts You Never Knew About Your Body

30 incredible facts about the human body that will deeply impress you. We bet you’ve never heard about half of them! We tend to think that we know our bodies perfectly. We are aware of how they work and what kinds of processes occur in them every second. In fact, the human body is one complex and mysterious mechanism that sometimes confuses even the most qualified specialists — doctors and scientists.

SUMMARY
1. A tongue print is absolutely unique.
2. A single hair can hold the weight of a hanging apple.
3. The number of bacteria in a person’s mouth is equal to the number of people living on Earth, or even more.
4. Nails that are soft and brittle, with no moon, could indicate an overactive thyroid.
5. The speed of an incoming brain impulse is about 400 km/h.
6. There are not just four different blood types as we used to think but in fact 29!
7. Over the course of just one day, our blood ’runs’ the distance of 11,9999 miles (or 19,312 kilometers).
8. Men also have glands that can produce milk, but its production represents an abnormality for the male body.
9. A human makes approximately 20,000 breaths per day.
10. Almost all people in the world have special mites on their eyelashes called Demodex.
11. A human eye can distinguish up to 10 million different colors. But our brain can’t remember all of them.
12. Our ears keep on growing throughout our lives with almost unbelievable speed — a quarter of a millimeter per year!
13. The heart beats 35 million times a year.
14. Every day, the human body loses about one million skin cells — that amounts to 4,5 lbs. (or 2 kilos) every year.
15. 1 square centimeter of your skin contains around a hundred pain sensors.
16. This might be very surprising to some, but 26% of men also experience PMS.
17. The average person consumes about 77,000 lbs. (or 35 tons) of food during his or her life.
18. A human spends about five years of their life blinking. Fortunately, we can do many other things simultaneously!
19. 100,000 chemical reactions occur every second in our brains.
20. Women cry average 30 to 64 times a year, and men cry just 6 to 17 times.
21. Smiling triggers 17 muscles of the face while crying activates 43. So smile more!
22. A man’s face preserves its youthful appearance a lot longer than a woman’s face does.
23. The total length of all the nerves in the human body is 46 miles (or 75 km).
24. Boys have fewer taste buds on the surface of their tongues than girls do.
25. All human beings in the world began their existence as females. X and Y chromosomes are responsible for determining an individual’s sex.
26. Men can discern far fewer shades of color than women can, and the reason for this is quite simple. Color perception is determined by retinal cone cells.
27. Women blink twice as much as men. Also, women’s hearts beat faster than men’s.
28. The speed of your sneeze is 100 miles per hour (or 140 km per hour).
29. A feeling of thirst occurs when water loss is equal to 1% of your body weight. The loss of more than 5% can cause fainting, and more than 10% cause death from dehydration.
30. The muscles which help your eyes to focus complete around 100,000 movements a day.

I was a board certified dispensing optician, but left the industry ten years ago. You could have knocked me over with a feather with the fact that cones, one of two types of visual perception cells, were directed by the X chromosome, and double in women what they are in men. We didn't know that when I studied. Question: What about rods, the other type of visual perception cells? Are they also determined by the X chromosome and twice as numerous in female eyes? Also, the statement that the human eye can discern ten million colors, but our brains can't remember. I'm a little less jealous of the mantis shrimp's eyes now.
