The Internet is full of information you may not have thought of before. However, accessing this information is not always easy. Also, sometimes we don't have the energy to read long articles.

That's why I've briefly put together some interesting facts for you.

If you're ready, I'll start...

Why Do We Get Goosebumps?

Goosebumps are one of our body's many involuntary responses. There are actually several explanations for this strange phenomenon. Our hairs when miniature muscles contract and form depressions in our skin. This is inherited from our ancestors, whose thicker feathers would create a soft layer of warmth and insulation in the cold. However, our body hair has decreased over time and has no such serious function. On the other hand, goosebumps can also occur during times of stress or high emotion due to a sudden rush of adrenaline, just as a cat's hair rises when threatened.

Why Do We Look Better in the Mirror?

The real reason we don't like the way you look in photos is a little more complicated than just not having our hair that day. Our mirror image is actually an inverted version of our real self. Which means we're used to seeing someone who doesn't really exist. On the other hand, for the same reason, we expect the image we see in the mirror in photographs, which is why we are disappointed. however, our friends or family find the photo that we consider bad to be perfectly normal. Because they always see us from the opposite side as in the photos. If that's not scary enough, let's just say that different focal lengths in photos can completely change the shape of the face. So can we really know exactly what we look like?

Why Do We Hate Our Voice in Videos?

I don't want to upset you, but your disgusting voice is much more accurate than your usual speaking voice. Now I will tell you why we are so surprised when we listen to ourselves in video or audio recordings. The people around us only hear sound waves transmitted by the air when we speak, but our own voice we hear is a combination of external sound along with the internal acoustics of our bones. Also, the sound reverberating around the skull produces rich, low-frequency pitches that don't exist outside. So, our voice is louder than we usually think.

Why Don't Our Eyes Get Cold?

You may not have thought of this before. However, unlike other parts of our body, our eyeballs cannot detect cold or heat due to the lack of temperature receptor cells. In fact, most of the human eye is located inside the skull, and in this part of our skull they are constantly pumped by a powerful supply of hot blood. In other words, it is almost impossible for the eyeballs to freeze at sub-zero temperatures as long as they are inside a living body containing bone tissue.

Why Is The Color Of The Shampoo Foam Always White?

There are hundreds of types of shampoos on the supermarket shelves, but it may seem strange that the shampoo foam is always white in color. But this can be completely solved with basic science. The dyes used in shampoo are already highly diluted and only increase as they form bubbles by mixing with air and water molecules. It's like inflating a red balloon until its color fades. In addition, scattering of light is also included, as the rays striking the small bubbles are directed in various directions due to large irregularities in the molecular structure of the foam. These numerous luminous surfaces make it almost impossible for the human eye to perceive the remaining colors.
