1. Most people breathe between 12 and 20 times a minute.
2. A lot of people breathe mainly through one nostril at a time.
3. You probably blink around 15 times a minute.
4. Speaking of your eyes, there are mites living in your eyelashes right now.
And also around your nose and in your ears and in the oil-secreting sebaceous glands in your pores. There are two kinds of mites that inhabit human faces: Demodex folliculorum, which live in hair follicles, and Demodex brevis, which live in your sebaceous glands. They have eight stubby legs and elongated bodies, and a study published in PLOS One found that all participants over the age of 18 had Demodex DNA on their faces.
5. You can't breathe and swallow at the same time.
6. Your tongue is either resting at the top or bottom of your mouth.
7. There are more bacteria living in your mouth right now than there are humans on Earth.
8. The average adult has 10 pints of blood in their body.
9. Most adults' hearts beat between 60 and 100 times per minute.
10. This means your heart pumps around five litres of blood every minute.
11. Most people are susceptible to contagious yawning, even when they're not tired.
Seeing someone else yawn or even just reading the word "yawn" can trigger you to yawn yourself. Feeling sleepy?
12. Itching can also be contagious.
13. And finally, this is what your spine looks like if you were looking down at your phone while reading this post.
Have a nice day!
