There are many types of hobbies. Some of them are strange, such as piercing your skin with huge metal hooks with ropes attached to them, and dangling yourself from the ceiling. Others might enjoy riding down huge mountain hills on skis, snowboards, mountain boards, bikes, etc. However, some enjoy pastimes that are more tranquil and meditative. For example, the art of contortionism is a very peculiar hobby that is usually practiced by women and children, due to the natural stretchiness of their tendons.

The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the formula FeS2.
