1. Your Brain Can't Feel Pain While different parts of your body can experience pain, such as your fingers, arms, or legs, your brain itself doesn't have the ability to feel pain. It doesn't have any pain receptors, which means that if something damages your brain, you wouldn't be able to feel the pain from the inside. This is why brain surgeries can be carried out while the patient is awake, without any anesthesia. The doctors can monitor the patient's responses and ensure they don't cause any discomfort.
2. You Shed Millions of Skin Cells Every Day You might not notice it, but you constantly lose skin cells every day. In fact, you can shed between 30,000 to 40,000 dead skin cells per hour, which adds up to millions every day. These cells become part of the dust that accumulates on furniture and floors. Additionally, microscopic organisms such as dust mites feed on them.
3. Your Body Is Mostly Water Water is essential for your body to function properly. It helps regulate your body temperature, transports nutrients, and removes waste.

For instance, some people experience synesthesia, a condition where the senses overlap. They might see colors when they hear music or taste flavors when they touch certain textures. Additionally, some people can hear sounds that don't exist, a condition known as tinnitus. In conclusion, the human body is capable of incredible functions and phenomena. Even with all the scientific advancements, there's still a lot we don't fully understand about ourselves. These cold knowledge facts serve as a reminder of the fascinating mysteries within our own bodies.
