1. The small bumps on a keyboard
Have you ever noticed the small bumps on the F and J keys of your keyboard?

The bumps were first introduced in 1878 by the inventor Christopher Latham Sholes, who designed the QWERTY keyboard layout.
2. The purpose of the tiny pockets in jeans

3. The reason why pencils have a yellow color
The majority of pencils are yellow, but have you ever wondered why? The reason dates back to the 1800s in the United States when the best graphite came from China. To promote the high-quality of their product, pencil manufacturers started painting their pencils yellow, which was the color of royalty and respect in China.
4. The use of buttons on clothing
Buttons on clothing serve more than just a decorative purpose. They were first used in the 13th century as a way to close garments, but over time, they have also become a way to express social status, religiosity, or emotional and political affiliations. For example, the buttons on military uniforms signify rank or branch of service, and the number of buttons on a blazer or jacket reflects its formality.
