5 Amazing Facts About Your Body

Humans are amazing (and yes, as a human I’m biased). But seriously, the human body is a marvel of creation, and most people will live their entire lives without ever truly understanding just how impressive our bodies are. This list is by no means comprehensive, but here are a few of the bodies wonders to keep in mind.

  1. An adult human’s body contains 7 octillion atoms. If you’ve never heard the word octillion, 7 octillion looks like this: 7,000,000,000,000,000,000,000,000,000. That’s a lot of zeros.
  2. Each of the atoms in our bodies are billions of years old.
  3. You’re actually made up of more bacteria than you are of human. Bacterial cell count in the body compared to human cell count is 10:1, but this isn’t necessarily a bad thing. The enzymes from bacteria in the gut for instance help with food digestion.
  4. You have way more than just five senses. Your skin for instance, can sense heat before it actually touches anything hot due to heat sensors. Furthermore, even without the aid of your sight, you can locate parts of your own body, or even navigate a room that you’re familiar with.
  5. Do you have a cat? If you do have one, or really any other furry mammal, you may notice that when agitated it’s hair tends to stand on end. This can result in your pet looking bigger and more intimidating. This also happens in cold weather, allowing your pet to stay warm. As it turns out, human beings have that same tendency as well. When you get goosebumps, either out of fear or cold, the hairs on your arms become very stiff since the goosebumps are pushing the follicles upright. Of course, the overall effect is less impressive given that while most humans have plenty of hair, the hair itself is too fine and thin to be effective.
