At any given moment, your body contains (approximately) 2.5 trillion red blood cells. Did you know that your bone marrow is responsible for creating them?

It takes less than 20 seconds for a red blood cell to circumnavigate your entire body. Think that’s fast? Nerve impulses travel at a stunning rate of 400 km/h (249 mph). On the topic of speed, a sneeze can generate winds of around 166 km/h (100 mph).
In one year, your heart will beat approximately 30 trillion times (or 100,000 times a day). That means that our blood travels nearly 60,000 miles throughout our bodies each and every day.
The surface area of your lungs is large enough to cover half of a tennis court. They ought to be pretty big, considering you breathe about 2 million liters of air every day without even thinking!
Whenever you touch something, you’re sending a message to your brain at a whopping 124 mph.
Our noses are pretty fantastic. They have the ability to warm cold air, cool hot air, and filter impurities with each and every breath.
On just one square inch of your hand, you will find 9 feet of blood vessels, 600 pain sensors, 9000 nerve endings, 36 heat sensors, and 75 pressure sensors.
There is enough iron in your body that if you were to extract it, you could make a spike that would be strong enough to hold your weight.
There are approximately 625 sweat glands on 1 square inch of your skin.
If you saved all of your blinks during your lifetime for one ‘massive blink’ you would have to close your eyes for 1.2 years.
The aorta is the largest artery in your body, and it is almost the diameter of a garden hose. Your capillaries, however, are tiny. It takes 10 of them to equal the thickness of a human hair.
Babies start dreaming before they’re even born!
Your gluteus maximus (your @$$) is the biggest muscle in your body. Each cheek weighs about 2 lbs (without the layer of fat.) The smallest muscle on your body is the stapedius (in your ear) and it is one fifth of an inch long.
Your body burns calories just by existing. However, you actually burn more calories when asleep than you do being awake watching a show or movie.
Your eyes never grow. Your nose and ears never stop growing. Your teeth are as hard as rocks, and your thumbnails grow the slowest while your middle finger nails grow the fastest.
The act of winking utilizes 200 muscles. Also, your gut contains around 2.2 lbs. of bacteria.
