10 Amazing Human Body Facts

The human body is more weird and wonderful than you think. There are so many amazing facts about our bodies that many of us just don’t know, so we’re going to provide 10 of the best.

1. DNA

There isn’t that much difference between you and a banana. We’re not even kidding! Humans share 50% of their DNA with this delicious fruit.

2. Height

Do you ever look in the mirror first thing in the morning and feel a little bigger? That’s because humans are approximately 1 centimetre taller in the morning than they are in the evening.

3. Finger and Toenails

Have you ever wondered how long it takes for your finger and toenails to grow from base to tip? You have a lot of time on your hands. Here is the answer anyway: it takes 6 months.

4. Synesthesia

Have you ever looked at the colour green and felt like you were chewing on a mouthful of grass? If so, you could have a condition called synesthesia, which causes the senses to overlap – meaning some people can taste words and hear colours.

5. I.Q

Do you dream a lot? Lucky you! It is believed that the higher your I.Q is, the more you will dream.

6. Stomach Acid

Now we’re definitely not challenging you to test this one out at home, but the acid in your stomach is strong enough to dissolve razorblades.

7. Bladder

Do you ever pee for a really long time? That’s because your bladder is probably pretty full. In fact, a full bladder is believed to be roughly the same size as a softball.

8. Smell

Your nose can remember 50,000 different scents – which is why we can often recall smells from our past, which takes us back in time.

9. Tickle

We all love a good back or arm tickle every now and then, don’t we? Have you ever tried it on yourself and failed miserably? That’s because it is impossible for a human to tickle themselves.

10. Cells

Humans are basically mutations. Around 90% of the cells that make us human aren’t actually “human” in origin, as we’re mostly just bacteria and fungi. How lovely!
