Our bodies are complex, fascinating machines. Even though we live in them every single second, there are dozens of incredible things happening inside us right now that sound like complete science fiction!

Here are 5 unbelievable facts about the human body that will shock you:

1. Your Bones Are Stronger Than Steel Ounce for ounce, human bone is stronger than steel! A block of bone the size of a matchbox can support up to 9 tonnes of weight—four times more than concrete can bear.

2. Humans Actually Glow in the Dark It sounds crazy, but the human body gives off a tiny amount of visible light continuously! However, the light produced is 1,000 times weaker than the sensitivity of our eyes, making it invisible to the naked eye.

3. Your Stomach Can Dissolve Metal Your stomach acid (hydrochloric acid) is so powerful that it can dissolve razor blades! Luckily, the stomach lining produces a thick layer of mucus every few days to protect itself from digesting itself.

4. You Lose Almost Half a Kilo of Skin Every Year Your body sheds about 30,000 to 40,000 dead skin cells every single minute. In a typical lifetime, you will shed around 35 to 40 kilograms of skin cells, which makes up most of the dust in your home!

5. Your Heart Beats Over 100,000 Times a Day In just one day, your heart pumps over 7,500 liters of blood through thousands of miles of blood vessels. Over an average lifetime, your heart will beat more than 2.5 billion times without taking a single rest break!
