I need to learn about the different kinds of hats that people wear.

Hats are worn for many reasons, but they can generally be divided into two categories: headwear and safety gear. Headwear includes hats such as baseball caps, beanies, and fedoras, while safety gear includes hardhats, helmets, and goggles. There are also other types of headwear, including sun hats, newsboy hats, and cowboy hats, which are not considered safety gear.
