When we know something really well, we sometimes say,
“I know it like the back of my hand.” But how well do we really know our bodies?
Each person has a body. A thing we’ve grown up in, a thing we might be trying to downsize and a thing we will grow old in. But how much do we really know about our own bodies? I bet I can share an anatomy fact that’s new to you.

- Every hour an average person sheds about 600,000 particles of skin. That equals about a pound and a half each year.
- Hair is also shed. On a daily basis, an individual loses 60-100 strands of hair.
- Skin and hair aren’t the only human part that’s renewed. Apparently, a person’s stomach lining changes every three to four days. This continual rebirth keeps the strong acids used for digestion from eating up the stomach. One source declared stomach juices strong enough to dissolve razorblades.
- The small intestine is also involved in digestion. It’s the largest internal organ and can be 18 to 23 feet long.
- Another amazing organ is the lung. Although the human lung is about the size of an American football, inside it has a surface area as large as a tennis court. Lungs have thousands of branching airways and hollow cavities that hold air.
- impossible to sneeze with your eyes open. Sneezes regularly come out of the body at 100 mph.
- That’s pretty fast. A cough is slower. It clocks in at 60mph.
- And now we’re talking about the mouth. Know what the strongest muscle in the human body is? The tongue.
- Teeth are the only parts of the human body that can’t repair themselves because their outer layer is enamel, not living tissue.
- People need saliva to taste food. You can test this theory by drying off your tongue and trying to catch your snack’s favor.
- Know how much saliva you’ll probably produce in your lifetime? Enough to fill two swimming pools.
- If that fact makes you grin, you’ve just used 17 muscles. If it inspires a frown, you’ve used 43 muscles.
- Depending on when you’re reading my blog you may be taller or shorter. If it’s evening, you’ve lost about centimeter in height. That’s because standing, sitting and all the things we do daily compress the cartilage between bones.
